Each service is using MPA, so there are many pipes going at any given time. With two TOF, you are likely overheating the CPU Do you have airflow on the board? Are you using voxl-inspect-cpu to monitor how hot you are getting the CPU?

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

@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?

@amitga It wouldn't hurt to upgrade your VOXL to the latest platform release (system image + voxl-suite): https://developer.modalai.com/asset/view/91 System Image: 3.6.0 Suite: 0.5.0 I believe voxl-wifi has recieved some robustness updates since the release you're on.

@Chad-Sweet I'm trying to read some sensor data using UART/I2C, from within a Docker container. I will look into libmodal_pipe , thanks.

@amitga The only thing we use over the B2B on our add-on boards is USB 2.0 and some GPIO. If you give us some idea of what you are trying to accomplish we may be able to offer some suggestions.
