We use the modem from Mikroe the LTE IoT 9 Click | Mikroe
And is experience issues whit modem is just hanging under transparent mode opperation. so issues is like this:
Modem hang issue:
Short description: Modem can't start after several switches between LTE/GNSS modes.
According to hang image, modem reset by itself all time long. The only way to start it is total poweroff.
It can't be reset by RESET pin, because LTE IoT 9 Click module do not have it.
Modem can hang in 30 minutes, or several days, can't find the system of it. I just found, that poweroff modem with AT-command between LTE/GNSS switch make this time much longer.
So for now modem working is set as:
- Power ON
- Turn on GNSS
- Wait for GNSS fix
- Turn off GNSS
- Power off
- Power on
- Switch to LTE mode
- Data exchange
- Power off
From what you wrote it seems that it could be either related to hardware or software or both. We have here a module from Thales with a hardware form the other party. I think that it would make sense to report this to Mikroe.
So, is the module hanging or resetting in a loop?
Do you have any log with AT commands? Could you check the firmware version with ATI1 command.
