-
-This project is far from being finished, and there are still a lot of things to do for this project to become a firmware usable by the general public.
-
-Here a quick list out of my head of things to do for this project:
-
- - Improve BLE communication stability and reliability
- - Improve OTA and MCUBoot bootloader
- - Add more functionalities : Alarm, chronometer, configuration, activities, heart rate logging, games,...
- - Add more BLE functionalities : call notifications, agenda, configuration, data logging,...
- - Measure power consumption and improve battery life
- - Improve documentation, take better pictures and video than mine
- - Improve the UI
- - Create companion app for multiple OSes (Linux, Android, iOS) and platforms (desktop, ARM, mobile). Do not forget the other devices from Pine64 like [the Pinephone](https://www.pine64.org/pinephone/) and the [Pinebook Pro](https://www.pine64.org/pinebook-pro/).
- - Design a simple CI (preferably self-hosted and easy to reproduce).
-
-Do not hesitate to clone/fork the code, hack it and create pull-requests. I'll do my best to review and merge them :)

 MCUBoot is run at boot time. In normal operation, it just jumps to the reset handler of the application firmware to run it. Once the application firmware is running, MCUBoot does not run at all.

+# BLE FS
+---
+
+The BLE FS protocol in InfiniTime is mostly Adafruit's BLE file transfer protocol, as described in [adafruit/Adafruit_CircuitPython_BLE_File_Transfer](https://github.com/adafruit/Adafruit_CircuitPython_BLE_File_Transfer). There are some deviations, such as the status codes. These will be described later in the document.
+
+---
+
+## UUIDs
+
+There are two relevant UUIDs in this protocol: the version characteristic, and the raw transfer characteristic.
+
+### Version
+
+UUID: `adaf0100-4669-6c65-5472-616e73666572`
+
+The version characteristic returns the version of the protocol to which the sender adheres. It returns a single unsigned 32-bit integer. The latest version at the time of writing this is 4. 
+
+### Transfer
+
+UUID: `adaf0200-4669-6c65-5472-616e73666572`
+
+The transfer characteristic is responsible for all the data transfer between the client and the watch. It supports write and notify. Writing a packet on the characteristic results in a response via notify.
+
+---
+
+## Usage
+
+The separator for paths is `/`, and absolute paths must start with `/`.
+
+All of the following commands and responses are transferred via the transfer characteristic
+
+### Read file
+
+To begin reading a file, a header must first be sent. The header packet should be formatted like so:
+
+- Command (single byte): `0x10`
+- 1 byte of padding
+- Unsigned 16-bit integer encoding the length of the file path.
+- Unsigned 32-bit integer encoding the location at which to start reading the first chunk.
+- Unsigned 32-bit integer encoding the amount of bytes to be read.
+- File path: UTF-8 encoded string that is _not_ null terminated.
+
+To continue reading the file after this initial packet, the following packet should be sent until all the data has been received. No close command is required after the data has been received.
+
+- Command (single byte): `0x12`
+- Status: `0x01`
+- 2 bytes of padding
+- Unsigned 32-bit integer encoding the location at which to start reading the next chunk.
+- Unsigned 32-bit integer encoding the amount of bytes to be read. This may be different from the size in the header.
+
+Both of these commands receive the following response:
+
+- Command (single byte): `0x11`
+- Status (signed 8-bit integer)
+- 2 bytes of padding
+- Unsigned 32-bit integer encoding the offset of this chunk
+- Unsigned 32-bit integer encoding the total size of the file
+- Unsigned 32-bit integer encoding the amount of data in the current chunk
+- Contents of the current chunk
+
+### Write file
+
+To begin writing to a file, a header must first be sent. The header packet should be formatted like so:
+
+- Command (single byte): `0x20`
+- 1 byte of padding
+- Unsigned 16-bit integer encoding the length of the file path.
+- Unsigned 32-bit integer encoding the location at which to start writing to the file.
+- Unsigned 64-bit integer encoding the unix timestamp with nanosecond resolution. This will be used as the modification time. At the time of writing, this is not implemented in InfiniTime, but may be in the future.
+- Unsigned 32-bit integer encoding the size of the file that will be sent
+- File path: UTF-8 encoded string that is _not_ null terminated.
+
+To continue reading the file after this initial packet, the following packet should be sent until all the data has been sent and a response had been received with 0 free space. No close command is required after the data has been received.
+
+- Command (single byte): `0x22`
+- Status: `0x01`

+- Unsigned 32-bit integer encoding the amount of data the client can send until the file is full.
+
+### Delete file
+
+- Command (single byte): `0x30`
+- 1 byte of padding

+## Deviations
+
+This section describes the differences between Adafruit's spec and InfiniTime's implementation.
+
+### Status codes
+
+The status codes returned by InfiniTime are a signed 8-bit integer, rather than an unsigned one as described in the spec.
+
+InfiniTime uses LittleFS error codes rather than the ones described in the spec. Those codes can be found in [lfs.h](https://github.com/littlefs-project/littlefs/blob/master/lfs.h#L70).

+
+## Language
+
+The language of this project is **C++**, and all new code must be written in C++. (Modern) C++ provides a lot of useful tools and functionalities that are beneficial for embedded software development like `constexpr`, `template` and anything that provides zero-cost abstraction.
+
+C code is accepted if it comes from another library like FreeRTOS, NimBLE, LVGL or the NRF-SDK.

+# Firmware, InfiniTime, Bootloader, Recovery firmware, OTA, DFU... What is it?
+
+You may have already encountered these words by reading the announcement, release notes, or [the wiki guide](https://wiki.pine64.org/wiki/Upgrade_PineTime_to_InfiniTime_1.0.0) and you may find them confusing if you're not familiar with the project.
+
+A **firmware** is software running on the embedded hardware of a device.
+
+InfiniTime has three distinct firmwares:
+
+ - **[InfiniTime](https://github.com/InfiniTimeOrg/InfiniTime)** is the operating system.
+ - **[The bootloader](https://github.com/JF002/pinetime-mcuboot-bootloader)** is responsible for safely applying firmware updates and runs before booting into InfiniTime.
+ - **The recovery firmware** is a special *application firmware* than can be loaded by the bootloader on user request. This firmware can be useful in case of serious issue, when the main application firmware cannot perform an OTA update correctly.
+
+**OTA** (**O**ver **T**he **A**ir) refers to updating of the firmware over BLE (**B**luetooth **L**ow **E**nergy). This is a functionality that allows the user to update the firmware on their device wirelessly.
+
+**DFU** (**D**evice **F**irmware **U**pdate) is the file format and protocol used to send the update of the firmware to the watch over-the-air. InfiniTime implements the (legacy) DFU protocol from Nordic Semiconductor (NRF).
+
+## Bootloader
+
+Most of the time, the bootloader just runs without your intervention (updating and loading the firmware).
+
+However, you can use the bootloader to rollback to the previous firmware, or load the recovery firmware using the push button:
+
+ - Press and hold the button until the pine cone is drawn in **blue** to force the rollback of the previous version of the firmware, even if you've already validated the current one.
+ - Press and hold the button until the pine cone is drawn in **red** to load the recovery firmware. This recovery firmware only provides BLE connectivity and OTA functionality.

-
-Basically, a **firmware** is just a software running on the embedded hardware of a device, the PineTime in this case.
-**InfiniTime** is based on 3 distinct **firmwares**:
- - **[InfiniTime](https://github.com/InfiniTimeOrg/InfiniTime)** itself, this is the *application firmware* running on the PineTime. This is the main firmware which provides most of the functionalities you'll use on a daily basis : bluetooth low-energy (BLE) connectivity, applications, watchfaces,...
- - **[The bootloader](https://github.com/JF002/pinetime-mcuboot-bootloader)** is responsible for safely applying **updates** of the *application firmware*, reverting them in case of issues and load the recovery firmware when requested.
- - **The recovery firmware** is a specific *application firmware* than can be loaded by the bootloader on user request. This firmware can be useful in case of serious issue, when the main application firmware cannot perform an OTA update correctly. Currently, this  recovery firmware is based on [InfiniTime 0.14.1](https://github.com/InfiniTimeOrg/InfiniTime/releases/tag/0.14.1).
-
-**OTA** and **DFU** refer to the update of the firmware over BLE (**B**luetooth **L**ow **E**nergy). **OTA** means **O**ver **T**he **A**ir, this is a functionality that allows the user to update the firmware how their device using a wireless communication like BLE. When we talk about **DFU** (**D**igital **F**irmware **U**pdate), we refer to the file format and protocol used to send the update of the firmware to the watch over-the-air. InfiniTime implement the (legacy) DFU protocol from Nordic Semiconductor (NRF).
-
-## How to check the version of InfiniTime and the bootloader?
-
-Since September 2020, all PineTimes (devkits or sealed) are flashed using the **[first iteration of the bootloader](https://github.com/lupyuen/pinetime-rust-mynewt/releases/tag/v4.1.7)** and **[InfiniTime 0.7.1](https://github.com/InfiniTimeOrg/InfiniTime/releases/tag/0.7.1)**. There was no recovery firmware at that time.
-
-The bootloader only runs when the watch starts (from an empty battery, for example) or after a reset (after a successful OTA or a manual reset - long push on the button).
-
-You can recognize this first iteration of the bootloader with it greenish **PINETIME** logo.
-
-![Old bootloader logo](oldbootloaderlogo.jpg)
-
-You can check the version of InfiniTime by opening the app *SystemInfo*. For version < 1.0:
-
-![InfiniTime 0.7.1 Application menu](appmenu-071.jpg)
-![InfiniTime 0.7.1 version](version-071.jpg)
-
-And for version >= 1.0 :
-
-![InfiniTime 1.0 version](version-1.0.jpg)
-
-PineTime shipped from June 2021 (to be confirmed) will be flashed with the [new version of the bootloader](https://github.com/JF002/pinetime-mcuboot-bootloader/releases/tag/1.0.0), the [recovery firmware](https://github.com/InfiniTimeOrg/InfiniTime/releases/tag/0.14.1) and [InfiniTime 1.0](https://github.com/InfiniTimeOrg/InfiniTime/releases/tag/1.0.0).
-
-The bootloader is easily recognizable with it white pine cone that is progressively drawn in green. It also displays its own version on the bottom (1.0.0 as of now).
-
-![Bootloader 1.0](bootloader-1.0.jpg)
-
-## How to update your PineTime?
-
-To update your PineTime, you can use one of the compatible companion applications. Here are the main ones:
-
- - **[Amazfish](https://github.com/piggz/harbour-amazfish)** (Desktop Linux, mobile Linux, SailfishOS, runs on the PinebookPro and the Pinephone)
- - **[Gadgetbridge](https://www.gadgetbridge.org/)** (Android)
- - **[Siglo](https://github.com/alexr4535/siglo)** (Linux, GTK based)
- - **NRFConnect** (closed source, Android & iOS).
-
-See [this page](ota-gadgetbridge-nrfconnect.md) for more info about the OTA procedure using Gadgetbridge and NRFConnect.
-
-### From InfiniTime 0.7.1 / old bootloader
-
-If your PineTime is currently running InfiniTime 0.7.1 and the old bootloader, we strongly recommend you update them to more recent version (Bootloader 1.0.0 and InfiniTime 1.0.0 as of now). We also recommend you install the recovery firmware once the bootloader is up-do-date.
-
-Using the companion app of your choice, you'll need to apply the OTA procedure for these 3 firmwares in this sequence (failing to follow this specific order might temporarily or permanently brick your device):
-
- 1. Flash the latest version of InfiniTime. The file to upload is named **pinetime-mcuboot-app-dfu-x.y.z.zip**. Here is the link to [InfiniTime 1.0](https://github.com/InfiniTimeOrg/InfiniTime/releases/download/1.0.0/pinetime-mcuboot-app-dfu-1.0.0.zip).
- 2. Update the bootloader by applying the OTA procedure with the file named [**reloader-mcuboot.zip** from the repo of the bootloader](https://github.com/JF002/pinetime-mcuboot-bootloader/releases/download/1.0.0/reloader-mcuboot.zip).
- 3. Install the recovery firmware by applying the OTA procedure with the file named [**pinetime-mcuboot-recovery-loader-dfu-0.14.1.zip** from the version 0.14.1 of InfiniTime](https://github.com/InfiniTimeOrg/InfiniTime/releases/download/0.14.1/pinetime-mcuboot-recovery-loader-dfu-0.14.1.zip).

-You'll find more info about this process in [this wiki page](https://wiki.pine64.org/wiki/Upgrade_PineTime_to_InfiniTime_1.0.0). You can also see the procedure in video [here](https://video.codingfield.com/videos/watch/831077c5-16f3-47b4-9b2b-c4bbfecc6529) and [here (from Amazfish)](https://video.codingfield.com/videos/watch/f7bffb3d-a6a1-43c4-8f01-f4aeff4adf9e)
-
-### From version > 1.0
-
-If you are already running the new "1.0.0" bootloader, all you have to do is update your version of InfiniTime when it'll be available. We'll write specific instructions when (if) we release a new version of the bootloader.
-
-### Firmware validation
-
-The bootloader requires a (manual) validation of the firmware. If the watch reset with an updated firmware that was not validated, the bootloader will consider it as non-functioning and will revert to the previous version of the firmware. This is a safety feature to prevent bricking your device with a faulty firmware.
-
-You can validate your updated firmware on InfiniTime >= 1.0 by following this simple procedure:
-
- - From the watchface, swipe **right** to display the *Quick Actions menu*
- - Open the **Settings** app by tapping the *gear* icon on the bottom right
- - Swipe down and tap on the entry named **Firmware**
- - This app shows the version that is currently running. If it's not validated yet, it displays 2 buttons:
-    - **Validate** to validate your firmware
-    - **Reset** to reset the watch and revert to the previously running version of the firmware

 ### Setting the time
 
-By default, InfiniTime starts on the digital watchface. It'll probably display the epoch time (1 Jan 1970, 00:00). The time will be automatically synchronized once you connect on of the companion app to your PineTime using BLE connectivity. InfiniTime does not provide any way to manually set the time for now.

-## InfiniTime releases and versions
-All releases of InfiniTime are available on the [release page of the GitHub repo](https://github.com/InfiniTimeOrg/InfiniTime/releases).
-
-Versions that are tagged as **RELEASE CANDIDATE** are pre-release versions, that are available for testing before actually releasing a new stable version. If you want to help us debug the project and provide stable versions to other user, you can use them. If you want stable and tested version, you should not flash these release candidate version.
-
-Release files are available under the *Assets* button.
-
-## How to upgrade Over-The-Air (OTA)
-OTA is the easiest method to upgrade InfiniTime. Note that it's only possible is your PineTime is already running InfiniTime (>= 0.7.1).
-
-2 companion apps provide support for OTA : 
- - [Gadgetbridge](https://gadgetbridge.org/) (open source, runs on Android, [available on F-Droid](https://f-droid.org/packages/nodomain.freeyourgadget.gadgetbridge/)). 
- - [NRFConnect](https://www.nordicsemi.com/Software-and-tools/Development-Tools/nRF-Connect-for-mobile) (close source, runs on Android and iOS).
- 
-Both applications need you to download the **DFU file** of InfiniTime. This file contains the new version of InfiniTime that will be flashed into your device. It's called **dfu-x.y.z.zip** (ex: dfu-0.9.0.zip) in the release note.
-![Dfu file](dfuFile.png )
-
-### Using Gadgetbridge
-Launch Gadgetbridge and tap on the **"+"** button on the bottom right to add a new device:
-
-![Gadgetbridge 0](gadgetbridge0.jpg)
-
-Wait for the scan to complete, your PineTime should be detected:
-
-![Gadgetbridge 1](gadgetbridge1.jpg)
-
-Tap on it. Gadgdetbridge will pair and connect to your device:
-
-![Gadgetbridge 2](gadgetbridge2.jpg)
-
-Now that Gadgetbridge is connected to your PineTime, use a file browser application (I'm using Seafile to browse my NAS) and browse to the DFU file (image-xxx.zip) you downloaded previously. Tap on it and open it using the Gadgetbridge application/firmware installer:
-
-![Gadgetbridge 3](gadgetbridge3.jpg)
-
-Read carefully the warning and tap **Install**:
-
-![Gadgetbridge 4](gadgetbridge4.jpg)
-
-Wait for the transfer to finish. Your PineTime should reset and reboot with the new version of InfiniTime!
-
-Don't forget to **validate** your firmware. In the InfiniTime go to the settings (swipe right, select gear icon) and Firmware option and click **validate**. Otherwise after reboot the previous firmware will be used.
-
-![Gadgetbridge 5](gadgetbridge5.jpg)
-
-### Using NRFConnect
-Open NRFConnect. Swipe down in the *Scanner* tab and wait for your device to appear:
-
-![NRFConnect 0](nrfconnect0.jpg)
-
-Tap on the *Connect* button on the right of your device. NRFConnect will connect to your PineTime and discover its characteristics. Tap on the **DFU** button on the top right:
-
-![NRFConnect 1](nrfconnect1.jpg)
-
-Select **Distribution packet (ZIP)**:
-
-![NRFConnect 2](nrfconnect2.jpg)
-
-Browse to the DFU file you downloaded previously, the DFU transfer will start automatically. When the transfer is finished, your PineTime will reset and restart on the new version of InfiniTime!
-
-Don't forget to **validate** your firmware. In the InfiniTime go to the settings (swipe right, select gear icon) and Firmware option and click **validate**. Otherwise after reboot the previous firmware will be used.
-
-![NRFConnect 3](nrfconnect3.jpg)
-
-## How to flash InfiniTime using the SWD interface
-Download the files **bootloader.bin**, **image-x.y.z.bin** and **pinetime-graphics-x.y.z.bin** from the release page:
-
-![Image file](imageFile.png )
-
-The bootloader reads a boot logo from the external SPI flash memory. The first step consists in flashing a tool in the MCU that will flash the boot logo into this SPI flash memory. This first step is optional but recommanded (the bootloader will display garbage on screen for a few second if you don't do it).
-Using your SWD tool, flash **pinetime-graphics-x.y.z.bin** at offset **0x0000**. Reset the MCU and wait for a few second, until the logo is completely drawn on the display.
-
-Then, using your SWD tool, flash those file at specific offset:
-
- - bootloader.bin : **0x0000**
- - image-x.y.z.bin : **0x8000**
-
-Reset and voilà, you're running InfiniTime on your PineTime!
- 
-If you are using OpenOCD with a STLinkV2, you can find more info [on this page](../openOCD.md).
-
-## How to synchronize the time
-
-### Using Gadgetbridge
-Good news! Gadgetbridge **automatically** synchronizes the time when connecting to your PineTime!
-
-### Using any Chromium-based web browser
-You can use it from your PC, Mac, Android. Browsers now have BLE support.
-https://hubmartin.github.io/WebBLEWatch/
-
-### Using NRFConnect
-You must enable the **CTS** *GATT server* into NRFConnect so that InfiniTime can synchronize the time with your smartphone.
-
-Launch NRFConnect, tap the sandwich button on the top left and select *Configure GATT server*:
-
-![NRFConnect CTS 0](nrfconnectcts0.jpg)
-
-
-Tap *Add service* and select the server configuration *Current Time service*. Tap OK and connect to your PineTime, it should automcatically sync the time once the connection is established!

+## Updating with companion apps
+
+To update your PineTime, you can use one of the [compatible companion applications](/README.md#companion-apps).
+
+The updating process differs slightly on every companion app, so you'll need to familiarize yourself with the companion app of your choice.
+
+All releases of InfiniTime are available on the [release page of the GitHub repo](https://github.com/InfiniTimeOrg/InfiniTime/releases) under assets.
+
