Banglejs2 wont boot, stuck on "->Bluetooth

Hi - did anything happen that caused it to get into this state? Like you were trying to develop an app?

Or one cause is literally just that you held the button for too long when booting it up and it went into the failsafe mode - you have to hold the button while ==== goes across the screen, but if you keep holding past then it'll boot without loading and code which is what you are seeing. To fix all you need to do is long-press to reboot but then as soon as the ==== reaches the end of the line and the screen changes, release the button.

Or if you were developing code, the most likely issue is you were developing and left the IDE set to 'Write to Flash' which writes the app over the existing 'bootloader'.

All you have to do is connect with the App Loader, uninstall Bootloader and reinstall it. If you can't connect the issue may be that one of your devices that you used previously is currently paired (if you paired with the OS bluetooth menu) so then you have to unpair it from your PC's own Bluetooth menu and you'll be able to connect again.
