Hi,
I have a RUT241 used for sending SMS through the HTTP API.
The issue is that after a couple of months it has stopped working. The issue persist even with a system reboot. When testing sending a SMS using the mobile utilities web page, the UI hangs followed with a “Failed to send message”.
I’ve got the same issue during the first installation but I resolved setting the connection to 3G/2G/Auto (without the 4G).
I’ve tried to update the firmware to the latest version but nothing has changed.
I’ve also tried to set VoLTE to On and Off without any success.
Using SSH I’ve tried the command gsmctl -D -S -s "<phone_number> TestMessage"
The result is:
GSMCTL modem[0]: Debug mode enabled
GSMCTL Modem id: 0
GSMCTL modem[0]: Calling Send SMS
GSMCTL modem[0] SMS: Checking input format
GSMCTL modem[0] SMS: Calling LGSM SEND SMS
[gsmctl_send_sms:22] error: ERROR: Failed to parse response
