The BLE Hardware is an Silicon Labs BGM 123, the firmware have built in the BlueGecko OTA Services.

Your job is to make a small module, which manage the OTA Update.

Main part of this module is managed in code, set OTA-File, start OTA, GUI should represent, OTA is running, Successfull/not Successfull.

Project Description BLE-OTA Update

Android Spezifications:

min SDK 23

actual Compile SDK 28

actual Build Tools Version 28.0.3

actual Gradle Version 5.4.1

It musst be possible to make BLT-OTA Updates for SiliconLabs BGM121.

Like BlueGecko APP, Partial or Full OTA, but automated without user Inputs.

Therefore are following Inputs necessary:

- Programable MAC-Adress for detecting which device should be updated

- Programable Path - File Input which isn't visible for user

- Path

- File APP

- File Stack

- It musst work for Full and Partial OTA (Partial means only one File is updated)

- Programable MTU value 53 to 512

- Programable Priority values low, middle, high


- Button for Start Update, Including MAC-Adress and Name of Device

- State of Update (Running / Finished / Successfull, Not Successfull) with Button finish

Special Point:

If old Firmware is older then 02.00 we need two Updates, one Partial following of an Full OTA.

Therefore the Views should've instead of finish Button, continue Button and should start a Full OTA Update

Firmware Version is stored in GATT 0x180A Device Information -> 0x2A26 Firmware Revision String.

It contains 5 chars in scheme "02.1A" each char could be a number or letter.


We need an explanation of how we should include your code in our APP.
