I have programmed the pico with the given code and input my number and a test text. When I start it up it gets stuck in a startup loop. I can see that the sim is making a connection to the network before it restarts. I have made a few changes to the code in picture 1, to provide the device longer to see if that would help make it out of the loop Et9zCD8IaZ .

Here is the picture showing it is making a connection to the network chrome_J1eJ0Xl80J .

Hello, Can you send the complete Output of the code, actually we know what you say but for confirmation, we need the output of the code. and when we run the code on our side code is not stuck

This is all I get.

Is there any documentation for the board?

sbcshop1 commented 2 years ago

OK, means you don't get the AT command response. Might be your 4G module is not 'ON' , when you run the code 4G module is automatic 'ON' . first of all check 4G module is ON condition, there is one NET LIGHT led in the board. If the 4G module is working in On condition the NET LIGHT blink continuously, and the device will give you AT response in the thonny terminal.There is another way to turn on Module by hardware. you can press the onboard power button for 4-6 sec, then release see the NET LIGHT led is blinking or not, NET LIGHT is not blinking then there is a fault in the board, if there is a fault in the board we replace the board

This is all I git.

Also just ran it in live and got that 4 response. Could that be ITU-T code 4 error?

Kashutu commented 2 years ago

It seems like the Pico is not sending data to the expansion board.

sbcshop1 commented 2 years ago

You saying Pico not sending the command , first you need to check raspberry Pi PICO GP pins all are working or not , by making all Pico Gp pins high
