Certified PX4 compatible ? #16

Open AlexisTM opened 7 years ago

AlexisTM commented 7 years ago

Hey,

What does mean "certified PX4 compatible"? Certified by who? What frames are going out of the module?

I am asking this because U-Blox M8T based solutions usually output NMEA which is not compaitble with the PX4 firmware (but compatible with Ardupilot).

Hello,

The M8T module is configured at startup to send RAWX and SFRBX messages (which contain the raw data information). Then RTKlib has been modified to create NAV-DOP, NAV-POSLLH, NAV-STATUS and NAV-VELNED ubx binary messages. This is an issue right now because PX4 (and Ardupilot) have moved (or are moving) to NAV-PVT message (which contains all the information summarised in one message). So right now and before porting to this new message it is not compatible with PX4, thanks por pointing out.

And so .... you do not provide patch or update to support NAV-PVT ?

Yet, the Ublox Tiny/XL/XXL RTK are compatible with the PX4 firmware right? (based on the ublox M8P)

klopezal commented 7 years ago

Yes we will!

klopezal commented 7 years ago

And yes Tiny/XL/XXL RTK are directly compatible.
