<span style="background:white">and compiled my code with patched Microbit-Python in PythonEditor-master:</span><br>

<span style="background:white">Unfortunately the "fix" did not work for me. If I use any PWM pin0.write_analog() together with radio.receive() commands, after some random time the micro:bit crashes (unresponsive). Usually reset button works to restart operation.</span><br>
<span style="background:white">I don't think my issue is anyhow relevant to power supply (I use reliable power sources); and I don't have any pins outputting PWM connected to any external devices...</span><br>
<span style="background:white">Please let me know if you need my *.py test scripts and hex files for diagnosing the issue.<o:p></o:p></span></span></p>
