I have a few quick questions to try to help figure out why the example code isn’t working for you.
1- Which version of modem and module are you using? The latest versions are modem: 34234 and module: 0.5.1.
2- Which version of the example code are you using? The latest version is v1.0
3- There are two debug outputs available, one from the application and one directly from the module. Could you please provide both of these outputs while the application is running? Steps to get these logs are as follows:
Application debug: Open tera term on “COMX: EDBG Virtual COM Port” @115200. You will need to be plugged into the debug_usb of the SAML21 Xplained evaluation board.
Module debug: Plug a mini USB into the of the module eval board and open tera term on the port that enumerated as port “C” @921600. Please see module upgrade procedures for proper com port enumeration.
Let these debug logs run for several minutes, at the same time, to collect a sufficient amount of data.
