How to add Dragino Lora/gps HAT to V3

This should mask the problem but it would be better to know where the code is getting a mode value of 0 from when it should be 0x80

sys.stderr.write("Mode <- %s\n" % MODE.lookup[mode | 0x80])

or we could try raising an exception which should give a traceback showing where the value of mode was set to zero.

 def set_mode(self, mode):
        """ Set the mode
        :param mode: Set the mode. Use constants.MODE class
        :return:    New mode
        """
        # the mode is backed up in self.mode
        if mode == self.mode:
            return mode

      if mode==0:
            raise Exception("Invalid mode value")

        if self.verbose:
            sys.stderr.write("Mode <- %s\n" % MODE.lookup[mode])
        self.mode = mode
        return self.spi.xfer([REG.LORA.OP_MODE | 0x80, mode])[1]

I find it hard to believe the Dragino RFM95’s are developing faults.
