Thank you Vivet for your help.
I am using a similar platform to Traccar in my own server. When I createa command and I check thebox "send sms"I recibe this message
SMS is not enabled - RuntimeException (BaseProtocol:127 < CommandsManager:66 < CommandResource:71 < ...)
If I don´t check the box then the command is sent but the fmt100 configuration doesn´t change.
I have write en similar Traccar Platfor,: setparam 1000: 123 whithout space and without password, if I send from my mobile, the FMT100 change, is I send It by Traccar then the FMT100 doesn´t change.
