I haven¡¯t tried to use the serial port on the G2 I have so it¡¯s possible that it¡¯s broken as the G2 wasn¡¯t new when Tanya sent it to me for developing the Servo firmware. ? Here¡¯s what I had with my G1? (with serial port modified to supply 5V on pin 1) ? ?????????????? Bluetooth??????????? G1 ?????????????? 1 ?????????????????????????????????????????

TX? 4 ??????????? ->?????????? 2???????????? RX ??????? RX? 5???????????? ->?????????? 5???????????? TX ?????????????? 6?????????????????????????????????????????? NC ? Which I am pretty sure is correct (please tell me if I¡¯ve got it wrong ¨C it would be easy to do). I¡¯ve checked the cable for continuity ? Baud rate is set to 9600 in Gemini.net and the lead is plugged into the Serial/GPS port on the G2. The web pages tell me that is also set to 9600 (unlike the HC port which is set to 57600). ? Gemini.net says connected, and then times out and gives up after a couple of attempts. ? Have goofed this up or? ? Cheers, David ? |
