Puck.js Connect to Adafruit Feather Board

Thank you both for the support! I put in an update using fanoush's recommendation on the Feather.
I removed the while loop so that it just continually loops. The serial response when clicking the Puck returns "I received: -1". The -1 means no data. So I'm not sure if that means the serial ports are not looking on the same space?

void loop() {
    incomingByte = ble.read();
    // say what you got:
    Serial.print("I received: ");
    Serial.println(incomingByte, DEC);
}
