Question

Dear Teltonika Forum

I've replaced an old Wavecom Fastrack 2G/3G modem with a TRB142. It's connected to a Mitshubishi E1071 PLC HMI panel by RS232. It is intended to send SMS from the E1071. I've managed to get it up and running, but I wonder if there is a way to send the AT-command:

AT+CMGF=1

at startup/boot? Without it, the command for sending SMS AT+CMGS="00xxxxxxx" only returns an error. I've tried adding

gsmctl -A AT+CMGF=1 in the startup script, but that didn't seem to work.

Best regards,

Roy Antonsen.

Answer 1

Hello

It might be that the modem is still in initialisation state, when command is executed, thus you could try adding a delay with additional line:

• sleep 60

Hi ZygimantasBliu,

thank you very much for your suggestion, I will test this. However, the TRB142 is configured in Modem mode-full control, do you think the gsmctl commands still works in the startup script? When trying random gsmctl commands in CLI, they don't seem to work when in Modem mode full control, only in partial control.

Best regards,

Answer 2

Hi everybody,

the gsmctl command in the startup script will not work when in full RS232 mode, because gsmctl is then disabled. Is there a way to use the startup-script to switch to full RS232 modem after init, so I could use gsmctl commands in the first lines in the startup-script?

Best regards,

Roy Antonsen.

A bunch of commands have to be executed to configure RS232 via CLI:

• uci set rs.rs232.enabled='1'
• uci set rs.rs232.baudrate='115200'
• uci set rs.rs232.databits='8'
• uci set rs.rs232.parity='none'
• uci set rs.rs232.stopbits='1'
• uci set rs.rs232.flowcontrol='none'
• uci set rs.rs232.type='modem'
• uci set rs.rs232.ctl_mode='full'
• uci commit
• reload_config
