BLE Connection problems + questions

Please could you start a new thread for this, with the example code you're using?

It's worth noting that:

• Only one device can be connected to Puck.js at a time
  
• Changing the services requires you to disconnect and then reconnect before they'll take effect.
  
  

If you're trying to read button clicks, did you consider:

• Just making it a BLE HID device
  
• Using advertising, and setting advertising data to the number of times the button was pressed (there's an example on the forum somewhere) - it's quick, easy, low-power, and doesn't require pairing. Because it's counting button presses it can cope with you pressing the button really fast as well.
  
  
  

@stevie4711 sorry I didn't get back to this - I think I found the underlying issue a few days ago though. The GitHub version has it fixed, but there's still a bit of tweaking needed (as fixing it caused the data rate to drop).
