Which version of system do you use? Khadas official images, self built images, or others?
official Ubuntu from OOWOW (22.04 v1.4)
Please describe your issue below:
I cant get smstools3 to work. I have the quectel EM06 4g module (official ad-on) (european version).
Internet works perfect. Smstools is a daemon and it looks at some folders. If you put a “sms-text” file in the map “sent”, the daemon processes it. In my case, its dropped in the map “failed” with “Fail_reason: Modem initialization failed” or “Fail_reason: Unknown” added to the “sms-text” file.
I dont have any incoming sms.
I can get a connection and send AT commands to EM06 with Minicom. (sudo minicom -D /dev/ttyUSB2). I tried sending AT commands with python to /dev/ttyUSB2 and get an error “error: Device or resource busy”.
In the smstools log i get the same error: “error: Device or resource busy”.
I have put the modem in “usbnet” mode, and in “normal” mode with minicom, no difference. (see khadas docs EM06 module)
I restarted the process as super-user, but no difference.
Any help or suggestions are welcome!
Kind regards
