Porting BLE_OTA_ServiceManager on a host processor and use the BlueNRG-LP as coprocessor

Associate III

Hello everyone,

I'm using a STM32L4 in a application and the BlueNRG-LP as a BLE module in network coprocessor mode with DTM SPI. I'd like to update my main firmware through BLE OTA, a kind of Bootloader OTA. So in my main MCU, there will be this Bootloader OTA at BASE_FLASH_ADRESS and the application above and in the BlueNRG-LP, the DTM SPI.

Ideally, this bootloader takes up BLE_OTA_ServiceManager principles, but ported on an external micro. Is this doable ? Or is there any other way to update the main app through BLE ?

Many thanks.
