PLS62T - Can't communicate over USB or ASC0 | Telit Cinterion IoT Developer Community

December 22, 2021 - 7:28pm, 633 views

I'm trying to troubleshoot a device that had some conflicting userware installed. I was struggling against both midlets to stop/uninstall them over ASC0 (being too stupid/lazy at the time to find a USB cable), and in the process I foolishly managed to:

1. Disable Userware/Autostart (and maybe set Userware/Autostart/Delay to a very large value)

2. Potentially mess up Userware/Stdout (not sure if I had last set it to ASC0 or NULL)

At this point, all I see on ASC0 is "^SYSLOADING" and then "SYSTEM.OUT STARTED", and it won't respond to AT commands. I also cannot get USB to respond to any commands. I've made sure that USB is configured in device manager with a 115200 baud and Hardware flow control.

I can get both ASC0 and USB working on a different PLS62T module without a problem, so it seems like the issue is related to the current configuration on the module. I'm just not sure how I can resolve this if I can't send it any AT commands.

Do you have any recommendations for troubleshooting this? I'm ultimately just trying to do a factory reset, so it's not a problem at all if that's a requirement.
