Hello Vinicius,

can you provide an logfile (/var/APM/logs)? You can try to compile and run ardupilot/libraries/AP_HAL/examples/RCInput (make bbbmini and execute sudo ./RCInput.elf) for debugging. I had similar problems with an old firmware at FrSky receivers.



Hi Mirko,

I will do this tests today.

This are the log file. What receiver are you using rigth now ?



I am using FrSky X8R, FrSky X4RSB and Spektrum Satellit SPM 9645.


Hi All,

I just checked out the Spektrum AR7700 PPM encoded output receiver with the BBBMINI and it works great.

Just have to use RCMAP to correct the PITCH, ROLL, and THROTTLE inputs.



Hello Vinicius,

Did you experienced any intermittent NO GPS problem with the Neo 6M ?

I am trying to get a solid status from this unit within Mission Planner but it is loosing signal a lot of time.

It seem to be pretty solid with the u-center program though.  I am experiencing with different location on the quad, and I would appreciate your feed back. Please note that I cannot get full constellation, I am working by the window, it is -30 Celsius tonight in Quebec... :-)

Hi Patrick, how are you ?

my gps is working pretty well, no issues - except initial 3d fix - around 3-5 mins.

Are you using 3.3 v, or 5v? using some voltage adjuster ?

What kind of cabled and connectors are you using ?



I tried both voltages with same result, and I am using FF jumpers.

As I just wrote, my Ublox Neo-M8N just works fine with the same setup.

I might investigate, but chances are that I will stick with the M8N, which is technically more appealing anyway.

Thanks for the reply and keep on flying with the BBB :-)

Hi Thomas,

do you use 5V VCC (receiver) R4 = 0 Ohm and R5 = open?




I am running the receiver on +5vdc and the resistors on the bottom of the board are: 1K, 10, 10, 1K.



Hi Mirko,

Has support for the COMPASS with I2C been considered.  I believe that is required for proper operation.



Hi David,

compass should work over I2C if the module is supported in the software.

Usually the HMC5983 is used these days in GPS/Compass Modules and it should work.



Hi Davis,

you can connect an external compass to P15, should run without any configuration.
