Since you're having trouble connecting with Bluetooth I would suggest trying to connect to it with different devices (phone, laptop, PC, etc.) by using the web IDE or app loader through a supported browser like chrome (not gadgetbridge).
If you don't see it right away it's possible it's already connected to something else in which case you can hold the button down for 6-10 sec for it to do a full reboot and hopefully show up as available to pair.
