Does espruino support bonding with a pin?

What happens is the PIN prompt appears on the camera and stays there until I sent it the value, it then shows a connection failed message for about 10 seconds and then shows a message saying no device is attached .

I have attached some (blurry!) pictures of the camera during this process.

Not sure if the no device connected is a bit of a red herring though as the camera shows this when you connect to it via nRF for example but aren't bonded yet.

For reference, here is an nRF log of performing the same process manually from an unbonded phone (so its essentially in the same state as the Pixl) to the camera and writing the same value to the characteristic UUID 5dd3465f-1aee-4299-8493-d2eca2f8e1bb

It is at the point of sending the value to that characteristic that the PIN screen is invoked on the camera and in this log I have obviously entered the PIN on the phone to complete the process and then am able to send to the characteristic and then register and receive notifications on the other characteristic.
