Controlling the Micro:bit from a Phone App 

Thanks for the tutorial I have been trying to connect my mobile but wasn't able to

Can u please create a tutorial I need that for my project

It didnt show up

@@cicihyrum3469 You may have to reload the page/project. You can also try this link to an empty project that contains the Devices toolbox. Just hit the edit button and customize it: makecode.microbit.org/_C733433TYJsd

@@palpatel8809 i made a tutorial on how to get the devices extension ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-iChe5aYWhbE.html

"Devices" is not being supported any longer, but it can still be added and used. See my other comments on this video for instructions to use it or look at this support article: support.microbit.org/support/solutions/articles/19000125262-makecode-devices-extension

@@bsiever thanks a lot

Yes. The only reason it was connected in the video was to allow me to show the details of programming it. Once it is programmed, you can connect while it's on battery power (or other forms of power supply).

Hi --- they MakeCode blocks for the Bluetooth Services used by the app can be used by other apps, including the one you are writing. Some of the specifications for those services can be found here: lancaster-university.github.io/microbit-docs/resources/bluetooth/bluetooth_profile.html . It's also possible to look at the service implementation in the source code of MakeCode and the micro:bit runtimes. If you haven't worked with bluetooth LE before, you may want to start by experimenting with a bluetooth browser App, like LightBlue (on iOS) or nRF Connect (iOS and Android).

@@bsiever Thanks!

Yes, you should be able to use it while also using USB serial!

Hi --- things to check: a) Are you sure Bluetooth is on/enabled on your phone? b) Did you update the project to disable Pairing (shown at 0:48 in the video)? c) You may want to try the "micro:bit pairing" (shown around 4:35 in the video). Pairing is/was required for the iOS app when the video was made. It might not be anymore. You might be able to try a different approach. Here's an old thread showing how the MBit app's controller could be used to interact with the micro:bit: forum.makecode.com/t/android-app-discord/7696/9 . It includes a link to generic code that worked at the time.

Hi Bill --- Are you sure you disabled "Pairing", which I show how to do at about 42 seconds into the video (ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-UuGTBZRwC-8.html)? This has to be done on each project and then, of course, the micro:bit needs to be updated with the new code. It may also be necessary to include at least one Bluetooth Service. The micro:bit _should_ show up in scans without much trouble if you disable pairing. (Disabling pairing makes it a lot easier to use Bitty Controller) Good Luck!

One more idea. It's also possible to use the Yahboom's MBit app to control almost anything over Bluetooth without the Devices blocks. Here's a thread on the Makecode Forum where I describe the approach: forum.makecode.com/t/android-app-discord/7696/9

@@bsiever Tried again, couldn't get BittyBlue to recognise the MicroBit, but after a couple of goes with the MicroBit IOS app I manage to display North and south arrows on the Microbit. It did keep disconnecting though.

Are you using iOS? Unfortunately, I don't think the Android version of the app includes this feature.

Sure! If you want to see how to send data from the micro:bit to a PC, see one of my other examples: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-eJiddQwKPck.html ; If you want the micro:bit to act like a Bluetooth HID device, see this demo: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-n4J5GN72N_4.html (It shows a MakeCode extension I made). For other Bluetooth options, search for Bluetooth here: github.com/carlosperate/awesome-microbit/

@@bsiever Okay, I've checked it:) And I have one more question, is there any way to connect with Robot MaqueenPlus Micro:bit to PC via bluetooth? I am asking, because if I use an extension for bluetooth then I cannot use an extension for MaqueenPlus. Do you know if there is any possibility to do it?

@@maciekkrasnicki9773 Maybe. I've created a "fork" of the MaQueen+ Extension that you can try, but I have not tested it at all. You can add it by going to add extensions and in the search bar enter "bsiever/pxt-DFRobot_MaqueenPlus_v20", hit enter, and select the tile. You can then add Bluetooth (and remove Radio). Or you can open this test project that has both the MaQueen blocks and Bluetooth blocks: makecode.microbit.org/_CeUd19asyJLH . By the way, the RGB lights may interfere with Bluetooth behavior. It may be necessary to not use both in the same script. Good luck!

@@maciekkrasnicki9773 In addition to my other suggestions, you may want to ask questions like this on the MakeCode Micro:bit forum: forum.makecode.com/c/microbit or ask DFRobot (makers of MaQueen)

@@bsiever Hi again! Thank you very much for your great help:) Unfortunately, I have one more question. I created an app for Andrid in App Inventor to control MaqueenPlus, but I have one problem with downloading a program to a micro:bit via MakeCode. I created this app using BlocklyTalky in App Inventor (it works without any problems) and in MakeCode (unfortunately when I want to download a program on micro:bit V2 there is an error 927). I' ve checked it and it means that "The program is incompatible with the micro:bit version you are using". Do you have any idea how I can fix it? Is there any version of BlocklyTalky for micro:bit V2? Or is there any way to change micro:bit V2 "software" for micro:bit V1 "software"? Or maybe You know another way to create such an app? Please let me know, have a nice day:)

See my comment below for details to add it yourself. Or try this project: makecode.microbit.org/_6p08qDUF2Vs8

It's no longer officially supported, so it doesn't show up in the Extensions list. "Devices" may still work in older projects. You can try using this empty project, which already includes the Devices toolbox: makecode.microbit.org/_C733433TYJsd

You can use kitronik move app it work just as nicely and is free and is on Android
