AP not responding to radio? Any tips?

Started this discussion. Last reply by RedQueen Mar 26, 2010. 4 Replies

Ardupilot finally seems to be working properly (running 2.5.02), achieved lock, telemetry output looks good.  However, the radio (Spektrum DX6i 2.4GHz / AR6200) inputs don't seem to have any effect. …Continue

Need all the sensors connected to aquire GPS lock?

I am simulating GPS via the FTDI and not able to get GPS lock.  Are all the servos and sensors required to be attached in order to aquire GPS lock? I am currently attaching the bind plug, applying…Continue

GPS data through FTDI interface?

Greetings all, Forgive me if this is a common noob question.  I have some ancillary equipment on my plane which needs GPS input.  I would like to pass the data through the FTDI cable as it would…Continue

As expected, the cables are backwards. Ground (black/brown) should be on the outside.

Here is my board minus the shield so you can more clearly see. Here are the connections if you can't clearly see them. Reciever Input & Outputs: Powered via rudder input through an extension cable to batt. Gear -> CTRL Elev ->…

Maybe you're plugging in your leads backwards? A photo of your setup would help...

AP not responding to radio? Any tips?

Ardupilot finally seems to be working properly (running 2.5.02), achieved lock, telemetry output looks good.  However, the radio (Spektrum DX6i 2.4GHz / AR6200) inputs don't seem to have any effect.  I have soldered the leads as specified in the diagrams and when the servos are connected directly to the reciever, they respond as they usually would. The mode switch does not trigger any lights, nor result in any messages in the telemetry.  Does anyone here have experience flying this setup that…See More

Problem worked around. Split out the FTDI cable and pushed Tx to the 5v GPS IN pin. For lack of a better solution that will have to do. Instant GPS lock.

Yup, sure was.. here is the snipp #define GPS_PROTOCOL 0 // 0 = NMEA, 1=SIRF, 2=uBlox, 3 = IMU, 5 = Simulated GPS mode (Debug) Here are my steps: 1) I set NMEA as the Protocol in code, and loaded to Ardupilot. 2) Started GPS emulator in NMEA mode…

Mike, when you were using NMEA emulation, had you set the config file to NMEA?

Like I mentioned above, I tried NMEA GPRMC + GPGGA sentences being supplied by the GPS emulator from the Configtool via FTDI at 38400 without success. Has anyone used the GPS Emulator located here to achieve a…

We don't use standard uBlox format. We use binary format, with special settings as described here. If you're just going to use a GPS emulator, you should set it to NMEA mode and set the ArduPilot config file to protocol 0 (NMEA) and make…

Yes, the emulator is the GPS Emulator included with the configtool package. The correct data is going down the FTDI cable as verified by my terminal program, it is UBlox data formatted correctly. Currently my header file is set to Ublox (option 2)…

The GPS comes from a special valid code from the GPS. The other analog sensors have nothing to do with the blue LED. I don"t know what protocall your emulator uses, but the correct one must be selected in the "whatever.h" file(header…

Need all the sensor connected to aquire GPS lock?

I am simulating GPS via the FTDI and not able to get GPS lock.  Are all the servos and sensors required to be attached in order to aquire GPS lock? I am currently attaching the bind plug, applying power, turning on RC radio, sending GPS via GPS emulator 1.2.6 over FTDI and waiting for the blinking GPS light to change....  nothing happens, just keeps blinking.  The AP sits in a removable tray and only has the elevator servo still attached while on my workbench.  Will the lack of XY and Z sensor…See More

Thanks for the reply :) It's not your understanding, it's my infinitessimal skill level lol. I am very new to this. 1) Well, right now it is the GPS emulator v.1.2.6 outputting UBlox to my onboard systems which are routing the data to…

Chris Anderson replied to RedQueen's discussion 'GPS data through FTDI interface?'
Not quite sure I understand the question, but I'll try a few answers: --First, if you're having trouble getting GPS lock: Which module are you using? If it's a uBlox, did you buy it preprogrammed for ArduPilot? --Second, about…

GPS data through FTDI interface?

Greetings all, Forgive me if this is a common noob question.  I have some ancillary equipment on my plane which needs GPS input.  I would like to pass the data through the FTDI cable as it would provide a much more convienient method for being able to route the GPS data through my systems than trying to directly attach the GPS to the AP and either recoding to output to my onboard systems or mounting a second GPS source. The onboard systems are routing the GPS data correctly to the FTDI…See More
