I don't own an Android device. nrf connect for mobile is failing with "Error: 3072 bytes were sent while 0 bytes were reported as received". Also getting a lot of timeouts.
This is a shame because following the failed update, my watch is basically bricked in DFU state.

Hi, bit of thread resurrection here. The option to use the nRF Toolbox is no longer available.
The DFU app doesn't seem to work either

Do you mean this? https://www.espruino.com/Puck.js+Eddystone
I've not got it to work yet though.

This was exactly the same for me. Needed to be

Hey, yeah, I completely closed Chrome, the computer, the lid, everything. Actually, it does work when you restart the computer, but it's then re-pairing following a sleep that was at issue (which is why I jumped on this issue - sorry JackJamesHoward)
I did connect to the Mac before figuring out the web bluetooth. Removing from the Mac bluetooth (using alt+click on the system tray), and then pairing from the browser first seems to have resolved the re-connection issue. It does now still show up in the system tray, but it's no longer a problem.
I did also need to do a Web IDE cache clear and reset the puck. Though I'm uncertain if that was related.
So, steps to fix my reconnection issue:
- Get OS to forget (
removeusing alt+click on the system tray) - Reset puck.
- Clear Browser caches.
- Start again from the Web IDE at https://www.espruino.com/ide/
- Get OS to forget (

I'm getting reconnection issues with Chrome 55 on a Macbook Pro 10.12
The Mac's bluetooth system tray thing shows the puck as connected, but the web bluetooth device scanning dialog in Chrome says "No bluetooth device found".
I do have other bluetooth devices attached, like a keyboard, and they also don't show up in the WebIDE Chrome dialog, so maybe the problem is there? I found the Google Chrome Github for web bluetooth to see if I could test that as a problem. The other devices are discoverable when I use their examples https://googlechrome.github.io/samples/web-bluetooth/device-information-characteristics.html from the list in https://googlechrome.github.io/samples/web-bluetooth/
The nRF Device Firmware Update (DFU) doesn't work unfortunately.
The web IDE doesn't discover the device because the watch has a
BANK0 INVALIDerror and I'm stuck in DfuTarg connect only.I think I'm just bricked now, unless I can find someone with an Android device.
