    @scosgrove , I just wanted to mention that our ESC driver for PX4 is also using UART running at 2Mbit. The Flight Control loop sends out commands at 800Hz and each control packet is 15 bytes long. Also one ESC channel (out of four) sends feedback to the DSP for every command. The feedback packet size is 16 bytes (at 800hz), that would be 12800 bytes/s. We almost never see missed RX data. I have also experimented with larger feedback packets (~42 bytes at 800hz = 33600 bytes/s received by DSP).

    Can you please clarify how the data is batched when the byte loss happens - how many bytes are sent without a break?

    So I have a VOXL2 and have it connected to my linux server currently that a client sent me.  Im able to connect via usb adb but it does not have internet access.

    Also I followed https://docs.modalai.com/voxl-portal-via-adb/. These instructions to get access to the portal on the localhost but I cant curl or navigate to it via browser. I tried this on a few systems.  Is there a way to get the voxl 2 to use USBc to act as a bridge to communicate out to the internet? I am able to get it to ping my Ubuntu server I have it plugged into via tcp but the Ubuntu system caan not return any communications.

    Any advice on this? Using the wifi module is not an option since it has a custom hat soldered to the top of it. I need to install a few python modules on it such as ultralytics and the rebuild a few things to support some custom vision models and being able to access the webserver to test them would be nice.

    Thank you for your time.

    Hello,

    I'm planning to create a custom server, which calls for reading essential data(i.e features detected, no. of points detected) from voxl-qvio-server. I'm planning on referring to the libmodal-pipe documentation link for building the server. I have few queries ie.

    I see the reference files here. Once I define my server, how and where do I build the server and integrate it within the existing MPA?
