| - | + | Any firmware that emits transmit frames onto a UART line connected to a computer will work; in my case, I used a modified version of the ga_stub_hb firmware build loaded onto a stock arduino to accomplish this. The only modification I made was to have the xbee driver write to the hardware serial lines instead of the software serial ports. This allows you to just use the arduino, instead of having to have a separate serial usb converter. | |
