How do you configure a Doodle Radio for use with an RB5? I see this page which says to run voxl-configure-modem on VOXL devices, but the RB5 doesn't have that tool (as expected). I did find that there's a tool called rb5-modem-configure, but that only provides the options of "quectel" and "telit". Do RB5s not support Doodle radios?

Thanks! I was able to do that. I just wanted to make sure before finding a tool small enough to be able to do that, and trying to twist the lens without knowing if it should be twisted.

I've been trying to record 4k video with the high res camera on the RB5. It's to my understanding that I'll have to wait to get 4k footage based on this topic. But even recording in 480p, the camera is very out of focus.

I'm recording video using the command below, not streaming.

gst-launch-1.0 -e qtiqmmfsrc camera=3 name=tracker ! video/x-h264,format=NV12,width=640,height=480,framerate=30/1 ! queue ! h264parse ! mp4mux ! filesink location=video.mp4

Things very close to the RB5 (within a few inches of the camera) are well in focus but past that, it's extremely blurry.
How would I adjust the focus? Should it be happening automatically?

Hello,

I have an RB5 which I've connected to many times through ADB and SSH. I exited an ADB shell one day, changed no wiring, then a short while later, I tried to open the shell back up using adb shell, only to find that there were no longer any recognized devices. For a few days, it seemed spotty on whether or not the RB5 would be recognized. Eventually, I couldn't connect at all. After talking through email with a contact from ModalAI, I tried booting into fastboot using these instructions, and I had errors due to /data/modalai and /home/linaro/eeprom/parameters not existing. I was able to get the camera calibration and test file from the ModalAI contact, and I flashed the RB5 successfully.

A few minutes later, I was getting ready to start a stream on the RB5 and I ran adb shell, only to get the error again: No devices/emulators found. I'm now back to before: I can't connect to the RB5 (using the same USB and power block as a few minutes prior when it worked). I also tried the fastboot instructions multiple times, and have not had any success.

Does anyone know why I might be unable to connect again?

I am interested in this as well. I'm actually interested in recording as opposed to streaming at the short term, but both are going to be useful. I've been recording with gstreamer using the following command:

gst-launch-1.0 -e qtiqmmfsrc camera=3 name=tracker ! video/x-h264,format=NV12,width=640,height=480,framerate=30/1 ! queue ! h264parse ! mp4mux ! filesink location=output.mp4

While that has worked, it's only recording 640x480. But if I try to record any higher of a resolution, the program ends very quickly, and no frames are recorded. I'm unsure why a resolution higher than 640x480 is causing any issues.
