we ran into a weird issue when receiving ZigBee packets on Windows. We are currently sending packets from a drone every 0.8s, but on Windows we are receiving only every ~5s. We aren't loosing packets, as the received packet ID's increment correctly. The strange thing is, when using an Ubuntu VM on the same computer it works perfectly, and we receive at about ~0.8s. We are using Digi-Xbee 1.4 and a "Xbee SMT Grove Dev Board" connected by USB for both sending and receiving. Here is the code were using to receive on both Windows and Ubuntu: def connect(self): self._device = XBeeDevice(self._port, self._baudRate) self._device.open() self._device.set_16bit_addr(XBee16BitAddress(utils.int_to_bytes(int(self._address)))) self._network = self._device.get_network() self._device.add_packet_received_callback(self._packetReceivedCallback) def _packetReceivedCallback(self, packet): print("Received!") #Processing after this Has anyone encountered this behavior before?
