Hello, I'm trying to use STM32WLE5CCU6 MCU as a radio module transceiver.
I have followed the MB1874_LowPower reference design down to it's 0.7 mm substrate thickness.
I connected the internal MCU RF power supply pins required like in the reference design and made sure i connected both of oscillators. I made sure to connect the necessary solder jumpers as well especially for the internal power supplies.
However I can't seem to be able to run the MCU as neither a transmitter or receiver.
But when the program reaches the line of code Radio.Rx() I can not communicate with MCU anymore via STM32 debugger. So I can't run my MCU with this program.
How do I fix this problem? Any help is appreciated.

Hello @AKahr.1
If you are using one of our examples. You need to take care of some difference between both STM32WL55 and STM32WLE55 MCUs that may cause this error. If no, I suggest you check your design with a HW expert.
Best Regards.
