Device Connection Failed,

When I try to connect to my banglejs 2, I get this error in the App loader. Here's the console log:

Sometimes, the logs only get to the puck.js:406 BLE Connected part, and the "Getting app list" at the bottom hangs at 0%. I do not know how this is triggered, and I haven't figured out how to affect it.
INFO
The watch is on the newest version (as of now), 2v13.
I also cannot use any other device to upload code (or apps) to the bangle js.
However, I can use nRF Connect to flash new firmware.
When I received the watch two days ago, I was able to upload code to it, and I haven't been able to since today. I don't remember installing any apps that might affect this, except the iOS integration app, which I've deleted with no effect. I have tried different instances of chromium, and a separate live linux system (mint) with no change.
Thanks in advance!

Hi - please can you try resetting the Bangle without loading code? https://www.espruino.com/Bangle.js2#rese­tting-without-loading-any-code

Just in case there is some code that disabled the Bluetooth UART service...

Also it's worth disabling and re-enabling Bluetooth on whatever device you're using to connect. You mentioned the iOS integration app, and I know iOS devices in particular cache the characteristics from BLE devices, so if they were connecting to a device and then the device changed (eg by adding iOS Integration) it'd be totally thrown until you restarted Bluetooth.

Also, did you then pair the Bangle with your iOS phone? If so the phone will now be automatically connecting via Bluetooth and stopping you connecting with any other device.

Hi,
Thanks for responding so quickly! Trying to start it without loading any code worked, but it unfortunately still doesn't connect or change anything. I removed the bangle js connection from the iPhone, but this doesn't seem to help. However, when booting, under the bangle js logo, there is a message: -> Bluetooth. I'm assuming that means the debug console is being sent to a bluetooth device? When I disconnect the bluetooth module from my computer, it doesn't appear anymore.

Alright, I seem to have figured it out. Once reconnecting the bluetooth module to my computer, I can now connect to the bangle js. It seems completely restarting everything and removing the bluetooth entry in the iPhone fixed my problem. I'm honestly not sure why this didn't work before, but thank you for your help!
