bleak.exc.BleakError: Device with address D6:66:C1:A7:CF:0F was not found. about kaspersmicrobit

Hi Martyn,

I'm afraid I will not be able to solve this issue 😞 . I only have one v1 micro:bit (I think it is a v1.5 actually) and it always gives me trouble on windows. In my case, whenever I pair it with windows, it will show the "C" on its led display. Is this also the case with your micro:bits? Besides trying to connect with kaspersmicrobit, I also failed connecting using bleak, and even failed with the windows runtime API.

You could try to connect directly with bleak, like this: bleak-device-info.py

Or scan for devices using bleak, like this: bleak-scan.py

But my guess is that connecting using bleak will give the same error, and that the scan will not find the micro:bits

Janick,
Thanks for your response.
I get no errors when pairing my micro:bits with Windows, just the expected tick on the LEDs when pairing complete.
I tried 'bleak-device-info.py' but got the same error message.
I also tried 'bleak-scan.py' and got a list of MAC addresses but none matched my micro:bits.

I have a few Linux boxes and Raspberry Pi's. I don't know if any have Bluetooth. If so I will try again under Linux.
Regards, Martyn

Just out of curiosity: which version number do your micro:bits have?

Let me know if you can claim success on linux 🥇

Janick,
All my micro:bits appear to be v1.3.
I could not achieve a bluetooth connection to any micro:bits from a Raspberry Pi4.
Will try with an Ubuntu system when I can find a suitable dongle.

Hi Martyn,

I found out that my microbit v1.5 works in windows when use a hex file generated with the "No pairing required" setting and with the microbit removed from the paired devices in windows.

Maybe this works for your v1.3 microbits too.

Documentation site and hex files are updated to prefer "No pairing require" as this works for the micro:bit v1

Closing this issue for now.
