Windows 7 : device is visible but connection failed

Great! Glad you got something working! And Archlinux has bluez 5.43 out of the box?

I still don't understand why it's being so picky on Windows though - others have had the same problems as you too.

Yes, Arch has this out of the box.

Hi guys.
I have a case where my device is visible but I do not have any web bluetooth button appearing in the Native IDE. Here is the console output:

The device is a Nordic "Thingy" based on NRF52. I don't use Puck.js because I temporarily lost it . . .

I tried with both CSR and Broadcom based BLE dongles, same result. In both cases the IDE finds the device but when I select a port, no Bluetooth port appears. Check box Connect over Bluetooth Smart (BTLE) via 'noble' is checked. Espruino Native IDE version is win64_0v65.9. Any idea?

There wouldn't be 'Web Bluetooth' appearing in the native IDE - any discovered devices would be shown in the 'Select a Port' menu.

It looks from the log like Bluetooth via noble is working well enough that it's detecting some devices - just I guess not the Nordic 'Thingy'. Are you sure it's actually flashed with the Espruino firmware and working? Can it be seen with something like the 'nRF connect' app?

The Nordic 'Thingy' has been renamed jpthingy.
Yes I flashed the espruino_1v92.111_nrf52832.hex firmware via a J-LINK debugger, but I wonder if I should have flashed the ZIP archive instead of the .hexonly... ?!?

Nope, flashing the hex file is the correct way of doing things, but if you flashed the hex file and it hasn't renamed itself Espruino NRF52832DK then the flashing hasn't worked.

That'd be why it's not appearing in the IDE anyway. I'm not sure if anyone's had it running on the Thingy yet - it might end up being more difficult than just flashing the DK's file.

OK the problem was the device flashing process, not the BLE adapter itself. For a reason, the J-Flash Lite tool did not flash the NRF52 the first time.
After some tests, both my CSR and Broadcom based BLE dongles are working fine :-)
