In the last 24 hours, i have been scratching my head over this.
The above solution worked for me and i am giving this feedback on my BT mini keyboard. I had this Bakker Elkhuizen M-board 870 Bluetooth keyboard on Channel 1 with my laptop working till yesterday morning and After the updating to Windows 10, I experienced the similar issue as mentioned above, where the Laptop prompts for the PIN. I tried as the above and the it was not getting through. Eventually this is what brought my keyboard attached to the laptop.
- As mentioned i was on channel 1 of the keyboard for laptop. I decided to take this out.
I used my phone to pair the Keyboard on channel 1. i was able to type into my phone.
2. I used the connect press button on the backside of keyboard for the Laptop to detect the Blue tooth keyboard. Once i see
the detection of the device displayed on the laptop screen under "add Bluetooth device", i switched to channel 2 (using
host select +2).
- The laptop prompted for a PIN. I entered 0000 on the laptop keyboard and pressed the connect tab, As soon i see the entry
is taken
4. I entered the 0000 on the Bluetooth keyboard and press enter on the Bluetooth keyboard.
- Surprise surprise i see the the Keyboard connected under the Bluetooth device on the laptop.
To me this is weird and these products are flaky!!!! though it is working and i am using it now :-)
I dont know if this makes you happy or cry!!!!
