  4G / LTE is a cellular protocol. The range and performance is determined by the cellular carrier whose service you are paying for. You can use your smartphone as a good proxy for performance. It would be best if you were comfortable with VPN and networking technologies before you try to build a cellular connected drone. There is know how and work involved.

  The Sentinel and VOXL 2 are open development platforms. ModalAI does not use or support Matlab UAV toolbox. So, if you need that feature you will need to figure out how to implement on VOXL 2. VOXL 2 is a Debian Linux system, so it is very flexible

  Thanks for the replies. The use case is low-bandwidth, short range communication to the VOXL using low-energy devices, which only have BLE.

  It sounds like QGC is buffering, have you reached out to the QGC team? The VOXL is a Linux device with standard Linux networking. You should be able to use standard Linux routing techniques to route your IP traffic

  @Hammas-Ali Yes, those would all be great features but we have not implemented them at this time. However, we may be able to provide guidance on the streaming re-connection issue. I'll ask some of our team members to take a look.

  @amitga Yes you can. That code shouldn't be there since it prevents the exact use case that you are trying to run.

  There should not be any difference in wifi performance between the two images. We only have the wifi driver as binary and do not have access to the source code. WiFi issues are almost always interference related. Maybe the channel changed? Can you look at a wifi analyzer app using your smartphone to see that it's on an open channel?

  Hi, We did a bit of digging and this was an issue with portal's handling of YUV422 images (which is a supported feature but we hadn't tested since we rarely see images in this format). If you look at the image from the uvc camera in voxl-streamer everything should look fine, and if you update your portal to >=v0.4.2 (this will be included in our next software release) everything should look fine.

  @Eric-Katzfey Yes, it works. I am not sure if changing the settings on the GCS side will affect the connection to other copter. But now it seems fine. Thanks.

  Also note that usb file transfers are much faster dealing with a single large file than hundreds of smaller ones, and the logging of camera images through voxl-logger currently saves each image in it's own file, so it's usually much faster to tar/zip a log folder and then pull the tarball.
