Add AT/Modem commands to Arducopter v2.9.1

Posted by Bernt Christian Egeland on February 9, 2013 at 12:50pm

Hi

I want to add these lines to arducopter software for Serial3 or telemetry:

AT+CGATT?   //attached to GPRS ?
AT+IPR=57600
AT+IFC=2,2   //"it's better to use hardware flow control"
AT+CIPMODE=1  //Enable transparent mode
AT+CSTT="internet"  //set APN
AT+CIICR   //open GPRS
AT+CIFSR      // Get local IP address
AT+CIPSERVER=1,1234//Start the TCP server, listening port:1234

 

I cant use the same structure as Andreas did in Modem_v2.6 becouse of the FastSerial.h are not beeing used any more i think?!?

Can someone point me in the right directions on how to implement these at commands?

 

 

Regards

Ludvig

    Hi

    If i load a basic sketch to my APM 2,5 board and use FastSerial.h with this commands:

    Serial.print("AT+CFUN=1,1");

    Then the sim900 responds.

     

     

    If i load Arducopter 2.9.1 and use this command:

    hal.uartA->print("AT+CFUN=1,1");

    The sim900 dont responds to the command. I have monitored the output and i get AT+CFUN=1,1  at baud 57600

     

    i dont really understand the diffrence between these command.

    Can someone please tell me what im doing wrong?

     

    Best Regards

    Ludvig

    Hi

     

    Can someone tell me how send AT commands from APM2.5 using HAL.

    I have been trying to use

    hal.uartC->println("AT+CFUN=1,1");

    as i understand  hal.uartC is 57600.

    But i dont think my APM send this command. Is this the right command to use??

     

    Regards
