@qubotics-admin It's in the voxl-fpv-dev branch of our px4 fork. See https://github.com/modalai/px4-firmware/blob/7e1625f20fac5f44a0034bebdb1e3d4027124684/src/modules/mavlink/mavlink_receiver.cpp#L108

@qubotics-admin The joystick button to use for turtle mode is set via the VOXL_ESC_T_ON parameter.

@cbay voxl-fpv-px4 is based on voxl-px4 but has some custom tuning code / parameters for our fpv drones that isn't in voxl-px4. So, it's kind of a superset. But there isn't anything related to low level i2c drivers so I have no idea how that could be causing this issue.

@jmltt
Yes, that looks correct.

The dongle is expected to have the specific Realtek RTL8812/8818 part in there. You'll see the RTL part number in the serial console or ifconfig (I think, I'm not SW).

@bendraper Actually, if you try to build the dev branch in voxl-cross:V4.4 it works but you first need to initialize the submodule with git submodule update --init. Can you try this with the dev branch and see if it works for you?

@bendraper Yes, we can recreate the failure. We need to release voxl-cross 4.8. We're working on it.

Hi @Jetson-Nano
Sorry for my delay, I was OoO when the first message came through.
In any event, I can only say we have no plans at the moment to explore this new Lepton, and I have not even reviewed the spec sheet, so I cannot offer any guidance on it.
Sorry I can't be of more help.

@Karteek-Gandiboyina Also, for reference: https://forum.modalai.com/topic/4403/starling-2-max-with-ublox-f9p-ultralight/7?_=1772217162290

@Karteek-Gandiboyina Unfortunately, we don't have any experience with that unit. It looks like it is hooked up correctly since you get a response from it. What baud rate did you change it to? You can try running the latest version of px4 but we have spent very little time testing it so use with extreme caution: http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-mainline-px4_1.17.0-1.0.2-202602240859_arm64.deb. Perhaps load that, remove the propellers, and just verify that it can properly see the GPS? And what if you just remove the baud rate option on the start command, does that change anything?
