I designed a custom PCB collecting data using a STM32L432KC, and transmitting it through a Nordic nrf52832 over BLE to a smartphone.
After this final prototype, I'd like to go to a Industrial architecture and adding the DFU OTA for both uC.
About the OTA DFU for the nordic, it is well documented. But about the STM32L432KC, I can't find any hints or topics.
Does anyone already did this ?
Any help would be greatly appreciated.
