That aligns with what we have posted on the datasheet here

We have published a video overview here. Let us know if this helps

I would try taking 2 pliers, hold the base and gently twist the lens. The most risk would be to the lens. If you don't care about the lens you can just install a new one. You focus the lens by twisting it in the threads. They are focused and then locked in place.

For both those modules, especially the m0026, you should be able to just unscrew the lens itself. M0026 using m12 style lenses and is designed so you can swap it out.

Look here, you should see hundreds of options

When an LTE modem is added to VOXL, the drone becomes a node on the Internet. It is now accessible from anywhere in the world.

This enables BVLOS flight, such as demonstrated here: https://youtu.be/lj1EZ_eTGPI

As well as robust communication for command, control and video under manual operation

As they are nodes on the Internet, other drones with LTE can communicate with each other as well

You can definitely write your own code for the VOXL found on the m500 drone. It's primary purpose is as a development drone to get your drone applications up and running quickly.

There is a lot of documentation here on how to develop: https://docs.modalai.com/developing-with-voxl/

It seems voxl-rtsp cannot run concurrently with voxl-cam-ros. We are working on a new camera-server to fan out the cameras more consistently, but that is probably a month away.

voxl-cam-ros uses libCamera which does support multiple clients of the same camera. It would be possible to write an rtsp server using the built in live555 and libCamera that would work concurrently with voxl-cam-ros.

Otherwise it seems in the meantime you will need to disable voxl-rtsp to get voxl-cam-ros to work

This is the type of receiver that might work (need to check compatibility with your transmitter) https://www.amazon.com/FrSky-Taranis-Compatible-Receiver-8-Channel/dp/B00RCAHHFM/ref=sr_1_3?keywords=rc+sbus+receiver&qid=1582226969&sr=8-3

You'll need to remove the Spektrum and install the Frsky receiver at J004 https://docs.modalai.com/voxl-flight-datasheet-connectors/#j1004---rc-input--spektrumsbususart6-connector

No, only a Spektrum transmitter will bind with a Spektrum receiver. You need a FrSky receiver connected to the Flight Core to bind to an FrSky transmitter.

Can you try the camera-test app? See if you can find a camera ID that enumerates as high-res. Maybe it's not actually located at ID 0 (the ID can change based on which cameras are connected)
