i have some issues with sending SMS from my PLC with using GET command.
Sometimes (especially after a reboot of the TRB) the first SMS is sent very fast and immediately after performing the GET command. Sometimes it tages quite long to send the SMS (> 2 minutes) and sometimes the command cannot be executed.
The command is curl -X GET “http://IP-Address/cgi-bin/sms_send?username=user&password=password&number=telnumber&text=message”
The command must be correct because as mentioned before, most of the times the sms is sent but very often with a massive delay.
