LoRaWAN FUOTA

[HKhan.4]

Good day

I am having many troubles with implementing FUOTA on my Dev kit.

Firstly, I have downloaded the STM32Cube_FW_WL_V1.3.1 firmware. When i edit the script files to build using the latest cube ide (1.19.0) the build fails with many errors. I then downgraded to V1.17.0 and changed my script file. The Lorawan FUota single core project was able to build and i was able to flash it to my device.

When i attempt fuota on my nucleo-wl55jc1 device everything happens as expected. However, When the device switches from class A to Class C and begins to receive fragments I encounter a hard fault:

The server continues to send fragments but the device has essentially stopped. I did deep dive online and found that this is a known issue:

Please could you add this to my enquiry I am losing hope that I may get FUOTA working.

Kind Regards,
