Sending data from JAVA app: avoid OK+CONN bonded message

Arduino
1

Hi,

I’m trying to send some data to the Blueduino from a JAVA application on a Raspbian image.

The code I’m using JAVA side is:

Runtime.getRuntime().exec("sudo gatttool -i hci0 -b AA:BB:CC:DD:EE:FF:GG --char-write-req -a 0x0029 -n myValue");

The code on the Blueduino is:

#define BAUD_RATE 9600

void setup() {
  Serial.begin(BAUD_RATE);
  Serial1.begin(BAUD_RATE);

  while (!Serial) {
    ; // wait for serial port to connect. Needed for Leonardo only
  }
  Serial.println("Hello!");
}

void loop() {
  if (Serial1.available() > 0) {
    Serial.print(char(Serial1.read()));
  }
}

I do receive the data I’m sending but I also “receive” those two more lines:

OK+CONN
bonded
myValue

Is there a way to get read of OK+CONN and bonded to just receive the data?

Thanks a lot :slight_smile:

Which auth mode do you use? Please check the document for AT+AUTH command. We’ll check the auth mode for bonded response.

Hi aprilpea,

Thanks again for the support.
I think you are right, I remembered I put the auth mode to 3: auth and bond

Sadly I can’t manage to run AT command anymore and have no idea why…
I uploaded an empty sketch and used termite with a USB to UART converter that I used previously to update to last firmware but it give me no answers…

Do you want to upgrade firmware again? For test AT command, you should just upload the sketch hardwareSerialMonitor
