RPi 3 GPIO 5 has a pull-up resistor, constantly firing "poweroff"

[96Octavian]

With a clean install of Raspbian Buster for the Rasperry Pi 3 mpradio works just out of the box but whenever I connect a bluetooth devices it receives a "poweroff" command and shuts down. I don't know why it receives it only after a bluetooth connection, but I logged around and found out that at line 140 of https://github.com/morrolinux/mpradio-py/blob/master/src/gpio_remote.py it was receiving an input from GPIO, self.remote_msg contained {'command': ['system', 'poweroff'], 'source': 'gpio'} Also when starting mpradio.py it gave me this warning: /home/pi/mpradio/src/gpio_remote.py:36: RuntimeWarning: A physical pull up resistor is fitted on this channel! GPIO.setup(5, GPIO.IN, pull_up_down=GPIO.PUD_UP) I think it's because GPIO5 in Pi 3 is always HIGH so it constantly triggers, maybe? I tried using GPIO6 but I get this error instead: Exception in thread Thread-7: Traceback (most recent call last): File "/usr/lib/python3.7/threading.py", line 917, in _bootstrap_inner self.run() File "/usr/lib/python3.7/threading.py", line 865, in run self._target(*self._args, **self._kwargs) File "/home/pi/mpradio/src/gpio_remote.py", line 36, in __run GPIO.setup(6, GPIO.IN, pull_up_down=GPIO.PUD_UP) ValueError: The channel sent is invalid on a Raspberry Pi Although this lets me play both FM and bluethoot just fine

I always felt it could cause trouble but eventually I forgot to fix that... You should try to remove pull_up_down=GPIO.PUD_UP and see how it works. Probably this will fix it, please let me know

I tried your suggestion and also tried using other pins but it didn't work, I found out that in https://github.com/morrolinux/mpradio-py/blob/f7ed8df7aef658c755701c2d74d57ee67f2ec4bc/src/gpio_remote.py#L45 if I write if input_state == GPIO.HIGH: instead, the event is not fired anymore, but I'm yet to add a button to test if it works

Ok let me know!
