Dabble gamepad not working

Projects General Guidance
1

Hey, I have a problem, I try to do a arduino car that I can control via bluetooth.
Im using a arduino leonardo with a hm-10 bluetooth module and a Dabble app.
the problem is that when I try to use the gamepad on dabble it doesn't work and I am not sure why. The app terminal is working just fine, so it's really confusing why it doesn't work with the gamepad as well.

The first aid is sending You this link: How to get the best out of this forum - Development Tools / IDE 1.x - Arduino Forum

Please read it and use it, and supply the requested but missing information.

Thanks for the link and the forum guide!

Here’s more detail on my setup:

Hardware

  • Arduino Leonardo
  • HM-10 Bluetooth module
  • Connections:
    • HM-10 TX → Arduino RX1 (pin 0)
    • HM-10 RX → Arduino TX1 (pin 1) via a 1k/2k voltage divider to reduce 5V to 3.3V
    • HM-10 is powered with 5V and GND
#define CUSTOM_SETTINGS
#define INCLUDE_GAMEPAD_MODULE
#include <Dabble.h>

void setup() {
  Serial.begin(250000);       // For debugging via USB
  Serial1.begin(9600);        // HM-10 connected here
  Dabble.begin(Serial1);
  pinMode(13, OUTPUT);
}

void loop() {
  Dabble.processInput();
  if (GamePad.isUpPressed()) {
    digitalWrite(13, HIGH);
  } else {
    digitalWrite(13, LOW);
  }
}

what works:
Dabble connects to hm-10(HMsoft in the dabble configuration)
terminal in dabble works without any problem

what doesn't work:
GamePad buttons don’t seem to trigger anything.
Sometimes, on the serial monitor, I see weird characters like:

�O�F�OK+LOSTOK+CONN�

do you think it's some sort of corrupted data or something ?
Am I missing something in how the GamePad module works with Dabble?

Is the IDE set to this speed? It look to high. Try using 115200, on both devices.

Looks like mismatched settings for the baudrate.

tried it before with 9600, it didn't work

and with 115200 too

You need to set the IDE to the same speed!

Have you tried their examples?
