Feather/NRF9160: Help Desired with AT Command and SMS PDU

I am having trouble brining my modem online and receiving SMS messages. I sometimes get a message but then I do not get anymore. I used an online decoder, and the message is a lot of time the same messages I received before. A lot of my AT commands do not properly work. For example, sometimes they return ERROR and I know for a fact that the command worked. before.

Also, the SMS PDU is very complex. I have a lot of trouble with it. A lot of places just do not seem to really explain it in a way that is easier for me to understand. Do you perhaps have any resources or code examples? I can read code really well and understand it in many different languages if that would help.

[1] Why do I get random ERROR response on AT commands from the modem?
[2] What is the proper initialization sequence to bring modem online for messages reliably?
[3] Why do I keep getting the same SMS message?
[4] How can I decode the SMS PDU?

[5] Is there any way to reboot the modem via the AT commands? I’ve got a design and it is kind of stuck where all I can send and receive is AT commands and I tried disabling the radio interface and brining it back online with CFUN but like I said it doesn’t seem to work and I get errors sometimes on certain AT commands.

Hey Charlie

I’ll need more detail or concrete error that you’re getting to help with feedback.

What firmware are you using? What version soft device? Which version of the nRF9160 Feather are you using?

Thanks
