How to pair microBit with Bluetooth?

Good morning,

Hoping you are well. We are not succeeding in pairing Bluetooth with our microBit. We have used two phones and a Galaxy S6 Lite tablet. The microBit does not appear as an “Available device.”

We have walked through this process several times. It seemed quite foolproof:

Can you provide a link or simple steps to link Bluetooth with the microBit please?

I also think such basic instructions need to be in the box with the kit.

Looking forward to your response. Have a great weekend.

Kind regrards,


Have you tried following the microbit instructions?

We went through the sequence once after a few trials, and the microBit didn’t connect when we restarted. Even after it said it was paired.

Every time we tried following that episode and it looks OK but never stops/prompts for the PASSCODE.

These are both Samsung machines. It seems that we are supposed to use the Samsung app, is that right? Ah just re-checked that link. YES, that is exactly the app we are using.

What specifically have you tried to get it to work? What elements have you confirmed are working correctly (by testing them with other known good hardware)?

There must be something different about what you’re doing compared to everyone else and the only way to find it will be to be very methodical

Hi Oliver,

Yes I agree. We have worked through the sequence of steps many times with two different Samsung devices.

  • Tablet SM-P610 – Galaxy Tab S6 Lite
  • Phone SM-A705YN – Galaxy A70

With both devices, the outcome and steps are the same. We get to the point where I should enter a code number from the microBit in the app. The microBit show a success image and the app says “Paired”.

However the phone won’t connect after rebooting. What we are not doing is entering a code because no code is shown.

Is there a way to independently connect via bluetooth without using this app? Just as some kind of smoke test, to confirm that it is working properly.

Another thought was that something might have remained “connected” during one of the failing attempts in memory. Is there a setp to perform a “factory reset” and wipe all state? Is there a different way to get the microBit started – Say from a PC or something?

I have bluetooth on my PC but I don’t have an app to use. If someone know of an app or program to connect that would be very good non-Samsung device to test with.

Open to sugggestions, the steps to get this to work do not seem complicated.

Many thanks for checking-in.

Kind regards,

Hey William,

This tutorial may have some more information on setting this up for you that was missed on the other page. I suspect that there’s some type of issue with the application, although it’s hard to tell without doing some troubleshooting against each point of failure and with a control. Do you have another microBit board that you can connect to with your devices to confirm that the issue is recurring? If not, I’d recommend updating the application, forgetting the bluetooth connection from your devices, and then reconnecting to see whether the same problem occurs.


My experience with the micro:Bit and Bluetooth was painless. But I had to find a procedure that worked. The Kitronik App was more the problem it would randomly drop out.

I use an old Samsung Galaxy S5 with no sim card and Bluetooth activated.
Start the Bluetooth on the micro:Bit.
Go into Settings on the phone, UNPAIR the micro:Bit and pair it again.
The micro:Bit LEDs should display a tick.
WAIT for that to go away and the micro:Bit to boot up.
KILL the App on the phone if it is already started.
Start the App and connect to the micro:Bit.

The parts in bold above were what caused the process to not work.



Further to previous post.
I tried the micro:Bit App linked above, not very impressed with it. The low rating and comments support my experience.

If you want to just program the micro:Bit, Suggest using the offline version of Microsoft Make Code PC application connected via a USB cable to the micro:Bit. It installs on your PC and has been quite successful for me. The online web version is less so.



I completely agree this is the way to go and limits the points of failure in your project, so if you have any issues with the boards or your setup then it’s much easier to diagnose. @william123871 Did you manage to get the micro: Bits running with Bluetooth in the end? It could be useful to others in the future to know how to solve this issue if it comes up again. Thanks.
