@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?

@Jainik-Mehta , can you please let me know what you are viewing in voxl-portal? A single camera (which) or all cameras?

@scosgrove Unfortunately, there isn't a whole lot of useful documentation about that. You kind of have to look through the Qualcomm source code to get an idea of what it is doing. One idea is to use the Qualcomm mini-dm debug tool. It is included with the Hexagon SDK. If you are connected to the USB port (i.e. you can use adb) then you can use mini-dm. This will output more information from the DSP as it is running and you may see some error messages coming out when you are seeing issues with data loss.

@voxl-phoenix J19 has pins for 2 UARTs. We put GNSS on one and RC on the other. So if you are able to hook up everything correctly, configure the TBS crossfire receiver correctly, and configure PX4 correctly then it should work.

@Eric-Katzfey I will need to add the support for up to 8 PWM outputs on VOXL 2 IO board. Right now it only supports 4. You should be able to do test flights without the gimbal with 4 PWM outputs.

@TomP I have updated the documentation at https://docs.modalai.com/voxl-ardupilot/. The VOXL 2 IO board with up to 4 PWM outputs is now supported and has been tested on a quadcopter with 4 PWM ESCs. You should be able to use this for arduplane now. We are putting together our own fixed wing test platform and hope to begin testing soon.

@voxl-phoenix VOXL 2 is really not a great place to start if you are new to drones. And the best way to start with a VOXL 2 is with one of our pre-built drones like the Starling 2 (https://www.modalai.com/products/starling-2), not with a bare board. The standard place to connect RC for PX4 is J19.

@Achyut-Sapariya Can you try updating to the latest SDK (1.3.5) and give it a go?

@voxl-phoenix What PX4 driver are you intending to use with it? And why don't you want to attach it to the "normal" RC UART on J19?

@griffin Unless you have your network setup to manually cycle IP addresses every so often then your PC's IP address should stay the same. They're usually logged by mac address
