I want to receive continous alerts from a sensor as SMS telling me if the sensor is ON or OFF. I have the following setup:
Sensor -> Viescomm VRM168 -> N30 (v7.41)
I know the input pin setup is correct because if I send an SMS
I get a reply
INPUT 1: ON
INPUT 2: OFF
INPUT 3: OFF
Or if Input 1 is OFF, the reply tells me it is OFF. So far it works. The problem is with input changes:
1. I send "nokia30 Get_Change_All"
2. I receive
INPUT 1: OK
INPUT 2: OK
INPUT 3: OK
3. I change the state of Input 1 to ON or OFF
4. I always receive the same message "INPUT 1: OFF", whether it really is ON or OFF.
So the N30 knows the state, but always sends the state change message for OFF. A bug?
Also everytime there is a state change, N30 forgets the Get_Change_All command, and the command has to be made again. Anything i can do to make the modem remember the command?
