I'm trying to figure out whether it is possible or not to upgrade the firmware of a host processor connected to BlueNRG-MS.


From this page it seems possible:

"The ST BlueDFU app allows WeSU (STEVAL-WESU1) boards to receive firmware images over-the-air from a smartphone and write them to the STM32L151 Flash memory."

There is even an application note dedicated to this : AN4486


But when digging in the code of STEVAL-WESU1 or X-CUBE-BLE I couldn't find where and how it is implemented.

I would like to adapt it to make the firmware of the module CMWX1ZZABZ-091 upgradeable from ble.

By the way I couldn't find the source code of ST_BLUE_DFU app. Is it possible to get it somewhere? The only feature I want to use from bluetooth is the OTA.

Thank you

Best Regards,
