Strange LED pattern when trying to connect to Puck.js over Bluetooth

In the past day, I have been having trouble connecting to my Puck.js over Bluetooth. Every time I try, the Puck lights up all three LEDs for around half a second and then the red LED for around a tenth of a second or less. Is this some sort of error message? I couldn't find a reference to it in the documentation.

Yes, that usually happens for an internal error (so nothing specifically related to your code).

Are you on the latest version of the firmware (1v92)?

Yeah I'm on 1v92. I tried reflashing the firmware too and I still got the error.

Wow, ok - that's the first time I've come across that. Had you been on one of the 'cutting edge' firmwares before, like 1v91.xyz?

Please can you try downgrading to 1v91 and then running the code linked here? http://forum.espruino.com/conversations/303637/#13590078

That should fix it for you - I'd be pretty sure it's related to the new 'bonding' feature. I imagine that somehow the flash memory that's used for bonding information has got corrupted. I have no idea how it happened though - was there anything in particular you remember doing that might have kicked it off?

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
