@Aaky voxl-tflite-server is a wrapper for TensorFlow Lite. So, anything you can get to work in standard TensorFlow Lite you should be able to get working in voxl-tflite-server

@Aaky great to hear, from my experience when the board is booting directly to fastboot it is often a power issue

@Alex-Kushleyev Thanks Alex. I will test this out. Also I will wait for your update on PX4 related integration of this ESC AUX OUT configuration. Also PWM only outputs in voxl_esc driver extension should suffice the need.

@modaltb I also want to check the stock availability of new TOF sensor over here. Is this TOF camera available for shipping currently? I cant see that on website so wanted to check with you.

@Aaky Should be fine. I fly with actual RC in HITL all the time.

@Aaky, I see what you are asking.

What is needed is the python binding to the C function int pipe_server_get_num_clients(int ch) , which is defined here

pympa_create_pub already is set up to return the MPA channel number, so we would just need to use that channel number of checking the number of clients.

I can implement this, but it will need to wait a few days. That is a good feature to have. If you would like to try implementing it yourself, you can add the bindings to :

https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-tools/-/blob/pympa-experimental/tools/pympa.cpp (add call to pipe_server_get_num_clients) in a similar way how other functions are called. add the actual python wrapper to: https://gitlab.com/voxl-public/voxl-sdk/utilities/voxl-mpa-tools/-/blob/pympa-experimental/tools/python/pympa.py then finally, when you call pympa_create_pub, save the pipe id and then pass it to check for clients.

@Eric-Katzfey Thanks Eric. I will try this out and let you know soon.

@Moderator Thank you. This clarifies everything.

@Eric-Katzfey This sounds like perfect plan. I would implement this and get back for any queries. Thank you Eric!

@Aaky , we are working on resolving the GPS detection issue related to uart baud rate changes - if forcing the baud rate works reliably then just stick with that !

@Aaky Well, unfortunately it isn't obvious what is going wrong. You will have to start by disabling everything and when px4 comes up reliably start enabling things to find out the culprit.

@Alex-Kushleyev Sorry to bug you again. Actually I have urgent customer requirements which could be fulfilled with robust VIO which I feel is going to be with dual cam open vins approach.

So I wanted to check with you if there is any update over dual cam open vins release? Also I have started my study over open source open vins algorithm and also would like to know some insights if there would be any modifications in open source open vins codebase or general camera and IMU driver integration? Dual camera part would need frame synchronisation if I am not wrong so is that part also handled in current open vins work?

It would really give me some pathway for further work if you can shade some light over here. Thank you!

@Aaky , the mixer should never output a value lower than mixer min (while armed).

@Aaky, yes if you change the camera configuration, just follow the same process:

copy correct sensorbin (with correct slot id) to /usr/lib/camera/ as previously discussed confirm the camera is detected using voxl-camera-server -l update camera config xml with correct camera ids - the camera id’s will start with zero and increment by 1 for each camera. The camera id assignment happens in order of the camera slot id. Slot id is mapped to the physical connector.

You may want to remove unused sensorbins from /usr/lib/camera just to avoid any confusion. You can always get them back from /usr/share/modalai/chi-cdk

At this point there is nothing new to share. New hardware designs and new software is required to achieve that use case which is a significant amount of work. We hope to have more to share within the next 12 months, but we don't have more precise estimates beyond that.

@Aaky Please follow the instructions in the readme file. https://gitlab.com/voxl-public/rb5-flight/rb5-flight-px4-build-docker/-/blob/master/README.md. It explains how to build the Docker image.
