Hi @Josh-Morehead S.BUS2 is not supported on ModalAI hardware (at this time). Please put your S.BUS2 device/receiver into legacy/conventional S.BUS mode. Additionally, for S.BUS receivers, please make sure you are using a cable meant for S.BUS that picks up 5V instead of the noted RC port we have which is 3.3V for Spektrum satellite receivers. This guide can help you convert a FCv1 S.BUS cable into FCv2: https://docs.modalai.com/cable-userguides/ See MCBL-00218-1 and MCBL-00064 both of which are based on MCBL-00018: https://docs.modalai.com/cable-datasheets/#mcbl-00018 We hope to have ready-made MCBL-00218/221 cables for purchase listed soon! Thanks and hope that helps.

@TPSetati Is there a chance you have two ground stations trying to connect to the drone at the same time?

It seems that the variable "external_fc" in voxl-mavlink-server.conf kept resetting to true, when it should remain false.

I have a 3 cell battery. I just looked at the vehicle settings in QGC and I see that the battery settings were set to the 4 cells. I changed it accordingly and the battery percentage now reads an acceptible 94%. Thank you.

Use cam name = "stereo" and there should be an option for using either the left or right stereo camera. As Chad pointed out you will need to also configure extrinsics if they aren't already for the stereo camera. https://gitlab.com/voxl-public/voxl-sdk/services/voxl-qvio-server/-/blob/master/server/config_file.h#L155 I have a PR to fix an issue with using a stereo camera here with the QVIO Server: https://gitlab.com/voxl-public/voxl-sdk/services/voxl-qvio-server/-/merge_requests/10 that you will need as well I believe.

@Matthew-Hood I don't know how to do that off the top of my head but it may be possible. All of what you're trying to do will be very difficult without having some kind of network connection to the drone in order for you ground station to communicate with it over a network

we tried a few different altitudes ranging from 30 feet AGL to 100 at 5 m/s. Same result. These test flights weren't long rang, the entire mission was only 2 waypoints, approximately 250 feet length mission. We'll try these test flights again using voxl-logger and try and diagnose the issues we're having.

Sure @hmlow here is a schematic snippet of that section so you have all the info: [image: 1680627538383-7c56d0e9-6cd1-488e-9b30-a189e04b455a-image.png]

@nshahrestani Sure, Here is the 4G modem: https://docs.modalai.com/lte-modem-and-usb-add-on-v2-datasheet/#power-consumption and Microhard 900MHz for reference: https://docs.modalai.com/microhard-add-on-datasheet/#power-consumption I think I need to add a section for the 5G modem.

We really don't have anything better, sorry. The Sentinel is really intended to be a development platform, and not support any mission critical activities.

Just tried to calibrated the stereo camera using ROS camera calibrator. Had to run the fixed voxl-mpa-to-ros. Because the ROS calibrator expects left and right to be exactly synchronized.

I'm using the Setinel. voxl-suite: 0.9.5

Good day We are working on a Sentinel with VOXL2 and are getting a similar CMD warning as well as similar INFO logs. The documentation for VOXL MPA to ROS says "Coming soon", so does the voxl-mpa-to-ros package also work for VOXL2 on Sentinel?

@José-Quintanilla As seen in the doc, the only port that supports hires is J2

Thank you for your help! I was able to download it directly and it works now. On my other device I was only able to build it, but on this device downloading it directly works.

Maybe it's the VOXL SDK diagram here? https://docs.modalai.com/voxl-sdk/

@tom Unfortunately it will be a few days before i can get that to you, but what i can do is list off the items i received. I received one sentinel drone with 5g modem and a set of propellers one pelican case 4 batteries 2 wall power adapters one alpha wireles dongle one voxl power module as pictured [image: 1680190839531-94fd33c4-5068-4aef-be6b-040f4f4c7f58-image.png] Note: the power module was taped to the alpha dongle (which was in the alpha box). from looking through the documentation the usb break out for the wifi on the drone with a 5G modem is the 4 pin JST GH for usb2.0 on the modem carrier board itself. it it looks like all i was missing was the cable that plugs into that board and the wifi dongle. i saw a shipping notification so it appears something is on its way. Thank you
