I’m trying to use an EM7455 from ThinkPenguin.com on an Ubuntu 22.04 machine. I’m able to connect through a T-Mobile IOT SIM without any problem.
But after an unspecified amount of time the connection will fail.
I think I found where I need to send the module AT+ZCDRUN=E\r\n because somebody decided that it would be a good idea to depend on windows only software.
The problem is that I can’t figure out how to send this AT command to the EM7455.
In windows it doesn’t present a com port to device manager.
In Linux it does seem to either.
This must be simple but I can’t figure it out.
