Hi, new to the forum so forgive me if this has been posted. I found this thread but it was locked:
viewtopic.php?p=2310354&hilit=sim+modules#p2275758
I recently bought https://www.mikroe.com/nb-iot-4-click and trying to hook it up to my Pico. I've connected 3.3and 5v as well as tx/rx to UART and rst and ri.
I've tried everything I can think of and can't get the unit to communicate. The power light is on but not network or rx/tx. I've tried connecting direct to my PC via the USB-C. The PC sees it on COM4 but I can't communicate with Putty - just no response from AT command.
Any thoughts?
