Your experience with Bluetooth HID on the Bangle?

Ok, that's interesting then. So I guess maybe what's happened is:

• The Bluetooth HID packet gets sent
  
• Espruino sees this, and calls the callback thinking it has actually got sent
  
• The original HID packet wasn't received so a resend is attempted
  
• The hidkbd code tries to send a second HID packet, but it fails because the original was still being sent
  
  

Does the 'key stuck on' problem happen more often than just the missed key?

If it is the problem above then I might be able to do something about sendHIDReport such that it didn't report the key as sent until it had actually 'gone', but I'm not sure I could do much about the missing initial keypress, as that might just be due to a particularly bad connection and the send just timing out.
