Hey Travis,

Thank you very much for your explanation and for passing on the link.
I understand how it was done now.

I will consider what is the next possible option for the project.  
I appreciate your time.

Best Regards,
Leon

@I_Dwyer @Chad-Sweet Hello all, has this issue been solved in and particular version, we too are facing the same issue, on HS1 the voxl-mavlink server is initiating but we are not able to see any data from this port. We are right now on the 1.5.3 build. Pls provided more info on the same.

Which version of PX4 are you running on the Pixhawk and do you have a magnetometer connected? EKF2 is generally unhappy about about starting without a magnetometer in PX4 1.11 so we patched the PX4 firmware for Flight Core to get around this. In PX4 1.12 and newer the following PX4 parameter can be set to allow EKF2 to allow position mode without a GPS/Mag

## disable mag SYS_HAS_MAG 0 EKF2_MAG_TYPE 5

@modaltb hello, when will the next SDK release be available? Would love to the UARTs working for external FC. Thank you.
