Hi,
I was just wondering if there is a fast way of building SCI communication infrastructure with SIM800l GSM module using C2000 in Simulink.
To do it, I imported SCI Simulink block to my model. It automatically imports all libraries supporting SCI communication.
After that I added System Update simulink block which adds C code to the existing Simulink model. The code looks as follows:
scib_xmit("AT",1,1);
delay(1000);
scib_xmit("AT+CMGF=1",1,1);
delay(1000);
scib_xmit("AT+CMGS=\"+44XXXXXXXXXX\"",1,1);
delay(2000);
scib_xmit("Hello",1,1);
After running Simulink model in external mode, code has been compiled. It sends data through SCI port with the specified frequency but my phone receiving data does not see anything incoming.
I am not getting any Simulink errors. The SIM800l is clearly connected to the network. Could someone explain if the problem is with my AT commands or something else?
