  • Got to the screen with the logo and MAC address, tried to connect again (from the apps page), no luck.

    It could be a case of PEBKAC, here's what I'm doing:

    • On watch: Settings > Make Connectable
    • Leave watch on the "Connectable" screen
    • Browse to https://banglejs.com/apps/
    • Click "Connect"
    • Browser dialogue pops up, scans, finds nothing

    Is there some way I can test the Bluetooth on the watch?

    you may try nrfConnect https://play.google.com/store/apps/detai­ls?id=no.nordicsemi.android.mcp&hl=en&gl­=US and check if you see it in the scan

    you can also follow the guide linked above but at the step
    "Keep pressing the button while ==== goes across the screen"
    you can release button when in the middle.
    This should stay in firmware update mode for a minute or so. Again check in nrfConnect, you may see it as DFUtarg device. This may work even if there is something wrong with Espruino firmware.
