Config BLUESMiRF with arduino sketch

Wireless & IoT
1

So I just picked up a BLUESMiRF RP-SMAfor a bluetooth car starter project I’m working on. One feature I’d like to implement in my arduino code is to lower the TX power when the car is running, so this would require the arduino sketch to enable the BS command mode and set the power level. Using Serial.print(“$$$”) the sketch makes the red led continuously flash (i.e. the BS enters cmd mode) but after that I can’t get anything to work. I would have thought that Serial.print(‘—’) would disable cmd mode, but no luck. I’ve also tried Serial.println and Serial.write also. Does anyone have any suggestions? I find it hard to believe that that hasn’t been done before.

Also, to make things sound even weirder … only Serial.print(“$$$”) works. Not Serial.println or Serial.write or even Serial.print(‘$$$’). For what its worth I’m using a Duemilanove 328.

Any help would be appreciated.

Serial.print(F(“$$$”)) also works but still can’t get the sketch to do anything after the BS enters cmd mode

Ok so for anyone that might find this useful you have to use print for the $$$ and println for everything else. The sketch code below will enter the BS cmd mode, write the power level value, then exit cmd mode.

Serial.print(“$$$”);

delay(1000);

Serial.println(“SY,FFFC”);

delay(1000);

Serial.println(“—”);
