this was almost giving me xbee rssi

getRSSI()

byte getRSSI() {

  // I'm only seeing 13 or 18... This function needs work.

	union {byte B; char C;} atCmd[3];
	AtCommandRequest atCmdReq;
	AtCommandResponse atResp;
	byte respLen, *resp, dBm;
	
	strcpy(&atCmd[0].C, "DB");
	atCmdReq = AtCommandRequest(&atCmd[0].B);
	atResp = AtCommandResponse();
	
	xbee.send(atCmdReq);
	if (xbee.readPacket(5000)) {
		if (xbee.getResponse().getApiId() == AT_COMMAND_RESPONSE) {
			xbee.getResponse().getAtCommandResponse(atResp);
			if (atResp.isOk()) {
				respLen = atResp.getValueLength();
				if (respLen == 1) {
					resp = atResp.getValue();
					dBm = resp[0];
					return dBm;
				} else {
					//Serial.println("Unexpected response");
				}
			} else {
				//Serial.println("ERROR");
			}
		} else {
			//Serial.println("Unknown response");
		}
	} else {
		//Serial.println("No response");
	}
}
