Bluno to BLE Gamepad
dfrobot 2020-01-17 22:43:37 2860 Views2 Replies Hi,
I have a Blune Beetle and a BLE Gamepad V2.
The BLuno is conenected to a string of WS2812b Leds. I am trying to write a sketch so when I press a button on the Gamepad the leds react.
I have managed to set the Gamepad as the CENTRAL and the Bluno as the PERIPHERAL. Made a unique BIND with the MAC address of the BLUNO.
When the Gamepad is switched on I get the 3 RX light blinks and then the 2 Rx light saying it is all connected.
When I press a button on the Gamepad the Tx light flashes which I think means they are communicating with each other.
However when I run the sketch below nothing happens.
I know it is not the led turning on and off code that is not working as it I have tested it on a none BLE comms sketch.
Any guidance would be appreciated
Many Thanks
Ian
