/It seems like whenever the microbit.uart.send_string() gets run in my script it just stops runnig. I tried debugging it but with no result.

My code:

from kaspersmicrobit import KaspersMicrobit
from kaspersmicrobit.bluetoothprofile.services import Service

uart_available = False
loop = False

with KaspersMicrobit.find_one_microbit(microbit_name='patat') as microbit:
    print(f'Bluetooth address: {microbit.address()}')
    print(f"Device name: {microbit.generic_access.read_device_name()}")

    if microbit.uart.is_available():
        print(f'{Service.UART} available')
        uart_available = True
    else:
        print(f'{Service.UART} not found')
        

    if uart_available:
        loop = True
        
        def verwerk_string(string: str):
            print(f"Received from microbit: '{string}'") 
            
            if string == "Test pc":
                print("Test pc ontvangen")
                microbit.uart.send_string("\nTest microbit\n")
                
            if string == "ontvangen":
                print("gelukt het werkt")
        

        while loop:
            microbit.uart.receive_string(verwerk_string)
            print("looping")

Hi,
I installed kaspersmicrobit using pip on my python 3.9.1 system running on Windows/10 and got no errors, see below:

After this I started python 3.9.1 and executed this one line:
from kaspersmicrobit import KaspersMicrobit

but got the following errors:

Am I doing something wrong?

I have installed Python 3.10.7 and pip installed kaspersmicrobit

I am running this code:

 import time
 from kaspersmicrobit import KaspersMicrobit
 CHANGE_THIS_TO_YOUR_MICROBIT_BLUETOOTH_ADDRESS = 'D6:66:C1:A7:CF:0F'
 def pressed(button):
     print(f"button {button} pressed")  
 with KaspersMicrobit(CHANGE_THIS_TO_YOUR_MICROBIT_BLUETOOTH_ADDRESS) as microbit:
     microbit.buttons.on_button_a(press=pressed)
     time.sleep(10)

and getting this error:

I have tried to add a screen-shot below which should show that:
I can see in Windows Settings \ Bluetooth that my microbit (vatig) is paired but not connected.
and in More Bluetooth Options, in the Hardware tab / Details / Association Endpoint Address = d6: 66:c1:a7:cf:0f

I have downloaded the simple script to my V1 microbits, which looks like this in Javascript:

bluetooth.onBluetoothConnected(function () {
    basic.showString("C")
})
bluetooth.onBluetoothDisconnected(function () {
    basic.showString("X")
})
bluetooth.startButtonService()
bluetooth.startAccelerometerService()
bluetooth.startIOPinService()
bluetooth.startLEDService()
bluetooth.startTemperatureService()
basic.showLeds(`
    # . . # #
    # . . . #
    # # # . .
    # . # . .
    # # # . .
    `)

What else can I do to try to diagnose this problem - I have tried with 3 different v1 microbits ?

Regards,
Martyn

With line: print(microbit.accelerometer.read())

I get error:

Sorry, but I have to get dinner now, so more details will follow up, but for now this is all I have

Update: This is on a Version 1 microbit

UPDATE: It was the hex file missing the accelerometer service, but yeah it now just keeps on giving me the 020 error even with the fix thingy that I use...

The example microbit-io_pin.py works fine, but reads all defined input ports. How can I read the value of 1 port i.e: Pin1?

Same for writing data to an output port. Say I have a led on pin0, which I configured as a digital output port. How would I write exactly to this pin0?

I am a total noob in python, so might be the reason why I can't figure this out ;-)

I don't have a mac to test kaspersmicrobit on. Let me know in a comment if it works!
First upgrade to the latest version:

$  pip install --upgrade kaspersmicrobit  

Please mention:

• the version of your micro:bit
• the python version you used
• if you used "No pairing required" or "JustWorks pairing"

When I try running the given program (in this link: https://kaspersmicrobit.readthedocs.io/en/stable/), I get an error like this:
"kaspersmicrobit.errors.BluetoothServiceNotFound: Could not find the service Service.BUTTON (uuid=e95d9882-251d-470a-a062-fa1922dfa9a8)
The available services on this micro:bit are:

• Generic Access Profile (Service.GENERIC_ACCESS uuid=00001800-0000-1000-8000-00805f9b34fb)
• Generic Attribute Profile (Service.GENERIC_ATTRIBUTE uuid=00001801-0000-1000-8000-00805f9b34fb)
• Nordic Semiconductor ASA (None uuid=0000fe59-0000-1000-8000-00805f9b34fb)
• Unknown (None uuid=e97dd91d-251d-470a-a062-fa1922dfa9a8)
• Device Information (Service.DEVICE_INFORMATION uuid=0000180a-0000-1000-8000-00805f9b34fb)
• MicroBit Event Service (Service.EVENT uuid=e95d93af-251d-470a-a062-fa1922dfa9a8)

Is this micro:bit loaded with the correct ".hex" file?"
I have the correct hex file and my microbit does get paired but, for some reason, it's not able to detect any services. Can anyone help me?
