STM32L476RG + IDW01M1 - WiFi hangs before connecting

Hi! I'm looking for some help in getting my STM32L476RG and IDW01M1 up and running with the FP-CLD-AZURE1 STM32Cube function pack. I also have the sensors.

I've flashed the board with the relevant binaries etc... The Azure_Sns_DM program accepts my azure and WiFi variables but just seems to hang after getting to the connection string:

Output below:

UART Initialized

I2C Initialized

STMicroelectronics Azure_Sns_DM:

WIFI Size=81 [bytes]

Wait 3 seconds for allowing User Button Control for changing it

Default Connection String : <redacted>

I can't for the life of me see whats going on after this point - AT commands don't seem to work.

If I could get some debug from the terminal that might give me a clue - but as I'm a newbie at all this I'm struggling...

Any help appreciated!

Thanks

Darren
