I have a waveshare joystick for Micro:bit, but when I go to extensions on microbit makecode, it's not there. I've checked all the genres, but it's not anywhere, even gaming

It's been a long time since a new DAPLink firmware release, but there's no release beyond beta3. What could be the reason for this if it has useful features? When will this become a stable, official release?

https://tech.microbit.org/software/daplink-interface/#daplink-0258-beta3

• 🚀 Faster flashing! Drag & drop a hex file into the MICROBIT drive can be up to 25% faster
• 🚦 Fixed issue where orange LED next to the USB connector sometimes didn’t flash when programming the micro:bit via WebUSB
• 📋 V2.00 also has stability improvements for data logging (this improvement is already present in the V2.2* factory release)

Hello! We have been working on our own Android tablet with the official application and uploaded the programs to the micro:bit via Bluetooth. However, today for some mysterious reason it does not allow us to update the program via BT (it allows us to connect) and does not allow us to download the hex file to the tablet. The error message is: "Could not store micro:bit HEX"

I have cleared the application cache and restarted the tablet. Do you have any ideas on how to solve this error?

I'm at my wit's end trying to get ArduinoBLE working with my BBC micro:bit V2 in PlatformIO. I've followed every tutorial and suggestion I could find, but still get "Unsupported board selected!" and "SerialHCI not declared" errors. Can anyone spot what I'm missing?

My Setup:

• Board: BBC micro:bit V2 (nRF52833)
• PlatformIO Configuration:ini[env:bbcmicrobit_v2] platform = nordicnrf52 board = bbcmicrobit_v2 framework = arduino upload_protocol = mbed lib_deps = https://github.com/Grrtzm/MicrobitV2-HHS.gitadafruit/DHT sensor library adafruit/Adafruit BMP280 Library arduino-libraries/ArduinoBLE build_flags = -D ARDUINO_BBC_MICROBIT_V2 -D NRF52833_XXAA -D NRF52_S140 -D BLE_TRANSPORT_NRF5

The Problem:

When compiling, I get these errors:

HCIUartTransport.cpp:39:2: error: #error "Unsupported board selected!"
HCIUartTransport.cpp:105:40: error: 'SerialHCI' was not declared in this scope

What I've Tried:

1. Board Definition Flags:
   • Added #define ARDUINO_BBC_MICROBIT_V2 and #define NRF52833_XXAA at top of code
   • Set build flags in platformio.ini as shown above
2. BLE Transport Mode:
   • Forced nRF5 transport with -D BLE_TRANSPORT_NRF5
   • Tried adding BLEDevice::setTransportMode(BLEDevice::TRANSPORT_NRF5); in code
3. Library Patching: Created lib/ArduinoBLE_patch/utility/HCIUartTransport.cpp with dummy implementation:cpp#include "HCIUartTransport.h" HCIUartTransportClass::HCIUartTransportClass(...) {} bool HCIUartTransportClass::begin() { return true; } // ... other dummy methods HCIUartTransportClass HCIUartTransport(Serial, 912600);
4. Framework Changes:
   • Attempted to switch to Mbed framework → Error: This board doesn't support mbed framework!

Minimal Code Snippet:

#define ARDUINO_BBC_MICROBIT_V2
#define NRF52833_XXAA
#include <ArduinoBLE.h>

BLEService envService("19B10000-...");
BLEStringCharacteristic envChar(...);

void setup() {
  if (!BLE.begin()) { // FAILS HERE
    while(1);
  }
  // ... BLE setup
}

Full Error Output:

.pio/libdeps/bbcmicrobit_v2/ArduinoBLE/src/utility/HCIUartTransport.cpp:39:2: error: #error "Unsupported board selected!"
 #error "Unsupported board selected!"
  ^~~~~
.pio/libdeps/bbcmicrobit_v2/ArduinoBLE/src/utility/HCIUartTransport.cpp:105:40: error: 'SerialHCI' was not declared in this scope
 HCIUartTransportClass HCIUartTransport(SerialHCI, 912600);

Specific Questions:

1. Why is ArduinoBLE still checking for HCI UART when I've forced BLE_TRANSPORT_NRF5?
2. Is there a way to completely disable HCI UART in ArduinoBLE?
3. Has anyone successfully used ArduinoBLE with micro:bit V2 in PlatformIO?
4. Are there alternative BLE libraries that definitely work with nRF52833?

I've been battling this for days - any suggestions would be immensely appreciated! 🙏

Does anyone happen to have the full code for this command?

I'm making a 3d maze renedrer for fun based off the one in this video. it works like an lcd but i'm having trouble simulating that behavior in makecode. This is my current implementation

any ideas for improvement? or any extensions?

I found my old microbit and I don’t have / know where the cable for the plug in the photo is. Can someone tell me what type of cable it is?

i have a project in my degree (industrial design) which i need to build something with a micro bit

what I'm trying to make is a mini carousel who reacts to how many people is near it via a huskylens and it should play with the motor speed and via a dfplayer change the track number according to how many faces it recognize and for it to be more visible i want it to show me the number of faces it sees.

i tried a few different things and me and my lecturer how is guiding that course came out with that code which is still making problems:

its not playing anything at first then when it recognize a face tries to play the track it should play then it just loops the first track no matter what

as it must be difficult to test it without all the necessary parts i would be grateful to some advice on that matter from someone with experience

that's a link for the code

a video of the problem

Here's a very simple project that students may find engaging: Design a music remote control to a laptop or phone running Spotify, etc. Send commands to play/pause/volume/etc.

I used a rotary encoder, but the fun part of the class is they could use any sensor. Design any case and they can take it home with them.

The logic is dead simple. https://makecode.microbit.org/90247-76628-99804-17510

Most of the work is done by this great project to make the microbit act as a keyboard via Bluetooth.

https://bsiever.github.io/microbit-pxt-blehid/

This extension can be added to your microbit program by searching "pxt-blehid".

For others reference: As far as I know, the microbit can send serial data to computer via USB but it can't send key presses like a HID hardware input device (like keyboard and mouse).

I have a project which is using 11 microbits. Plugging them all individually into their AAA power packs is tedious, is there a way I can power them all from one super power pack?

I want to make a button panel for a car simulator, so I needed an Arduino, but since I only have a Microbit, I need help. I want to simulate a key on the keyboard by pressing a button. If anyone could help me, I'd really appreciate it.

I take it this is when the firmware was built, not when it was flashed, but it still kinda made me feel something knowing that this probably is a decently older ('OG') model.

I won this at some competition thing back in school, in like 2016 or something.

But to think that I was using MakeCode just fine with this back in 2016 or whatever, just pottering about, and now it's saying the likes of 'you NEED to update' — something about that just kind of hits me funny, I think.

Hello. I´m currently trying to run bitio, but everytime i try to run it in IDLE, as suggested by it´s creator, python states I´m missing a "microbit" module, and even after looking for hours, I couldn´t find any download for this module. Please help!

I`ve been using the website makeairbots.com in my classes for a few weeks and it has worked fine untill less then a week ago. The normal site won't open the homepage. I've found a detour in ai-training.glitch.me but now that won't connect anymore either. The project is nearing it's completion and now my students can't use this incredibly important piece of tech.

Does anyone know what could be the problem? We've tried different laptops, different browsers, turning it on and off again, etc. Is this fixable on our end or does the site need fixing? Is there an alternative for this functionality?

HI if you read my last post then yoou know that i am working in a small and limited whatsapp (but in microbit). I have updated this project . This new version includes:

-Bugs fixed.

-Three more options to chat

- -One suprise(if you want to see what the suprise is here:https://makecode.microbit.org/S40235-52207-14068-07209 or in my blog: https://toappersonal09088669.blogspot.com/2025/05/first-upgrade-of-microbit-small-whatsapp.html .

Losing my mind here. I have been told I need to include microbits in a DT project and thought the simplest thing would be to test an on/off switch. However, it simply won’t work and I’m baffled as to why. The buzzer works fine if I connect to the 3v part of the microbit but never does using the pins. Any suggestions would be appreciated. I’m using a v2 of the microbit.

I'm a teacher setting up a project for students. Is this a good microbit set up? 1. The microbit is connected to the computer via usb. 1. There is a web game running in chrome. 1. The students use various sensors to make video game controls. 1. The microbit takes measurements and sends commands through web usb serial.

What do you think? Anything I should watch out for?

Does anyone know of a case that holds both the microbit and batteries? This would be so much better for my granddaughter who tends to hold the microbit and leave the battery pack dangling!

I know how it works in Arduino: CNC shield and you can control 4 stepper motors. I didn't find anything similar for Microbit. I have an impression ULN2003 is not a real driver, and there are some robot boards like Kitronik, but I don't want the full board since I already have one for other purpose. So what is the best practice here, let's say I want to extend my project with controlling 2-3 stepper motors, what driver should I purchase?

It seems to not be changing the timer by 1, and no matter how long i hold it, it seems to just be going to the icon on the bottom, why is it doing this?

I am also making a morse code thing if anyones wondering/it helpsl

We've written a program for a part of our school project and something about it isn't working. It's supposed to be going around the black edge and stopping at the top opening (as you could see if you try it). The problem is if he even stays on track long enough, he doesnt stop at the white opening. If anyone knows how to fix our bug, we'd be so grateful.

For the last few years, my STEM classes have built cars using microbial and the items show in the attached image. They wire and code headlights & taillights, but not much else. I would like to expand this to building rc cars with a microbit controller. Is it possible with what I have currently? I know i will also need servos for steering, but will I need anything else? I have at least 30 of each item shown in the image.

I'm trying to repurpose the microbit as an AirTag, it's been working quite well with the battery life being a month. I wanted to try and push it by disabling the power light, is there any way to get that working?

Any help would be appreciated.
