Puck.js bluetooth keyboard / batteries or something else?

Hi! I'm pretty sure there's nothing to worry about, and it won't be battery related.

I'm pretty sure DL2032 is fine - the only ones you have to watch out for are LR2032/LIR2032 as those actually have a higher voltage!

BLE Connected, queueing BLE restart for later

This would have happened every time - what it means is it's got to restart Bluetooth on the chip in order to add the HID support, but to do that it'd break the current connection so it waits until you're disconnected.

So I think there are a few possibilities:

• You need to upload to Flash, not RAM - because if you uploaded to RAM then when you disconnect power and reconnect everything will be lost and it'll go back to standard
  
• It's already paired with your computer, so when you disconnect from the IDE the computer doesn't actually disconnect, which means the Puck doesn't get to restart and add the bluetooth keyboard functionality - all you need to do there is just go into your OS's bluetooth settings and unpair it, then wait a bit and repair and it'll be fine
