Hello ST team,
We are developing an IoT module in which we are using STM32L496 and BG96 module. Our application code is written above middle ware and BG96 ST-MOD section of X_CUBE_AZURE. The functionality wise everything is working fine but in testing we are facing a issue. The ST controller hangs randomly and in hang condition it does not respond at all until power on reset its UART TX (debug UART2 and BG96 UART1 ) locked at logic high.
Our devices runs continuously then suddenly gets hang after working for more than 24 hrs or sometimes 8 hrs. Is there any known issues in X_CUBE_AZURE code which might cause this kind of issue and what is workaround.
We are at very crucial stage of project as our devices are going for production at end of this month so this issue needs to be solved asap.
Also would like to know how we can find the root cause for this issue as we are not able to trace what exactly causing this error.
Let us know if you require any other detail. Any help is appreciated.
Thanks in advance!

Hello,
I suggest to download latest X-CUBE-CELLULAR (V5) on st.com and check RN that will give access to modem RN.
Then check your modem FW version and update it if necessary.

This type of problems are also because HAL "lock" is not interrupt safe.
