high-speed data transmission via UART (no need to transfer images)

[marseric]

This is really a good project, thank you author.
Please tell me, I have two Raspberry Pi 3Bs.
I only need to use it for high-speed data (1 Mbps or higher will be great )transmission via UART (no need to transfer images).
How should I configure it? Thanks a lot

Set the data rates as low as 2, 5 or 6 Mbit/s on the air side. I guess you will want to use FEC for your data, so you will need to use the video module.

My suggestion:
You will not need most of the DroneBridge modules so you can disable them.
You can do that by disabling the service.
Running sudo systemctl disable start_db should do the trick.

Because the service is disabled you will need to run the Wifi-Adapter setup script manually on boot. To do that call python3.7 /home/pi/DroneBridge/startup/init_wifi.py on the air side and python3.7 /home/pi/DroneBridge/startup/init_wifi.py -g on the ground side. After that you can run the data transmission.

Here is some more detailed info on how to use the video module. On the air-side something like

sudo cat myUARTdatasource | video_air -n wifiinterface -n -c 200 -t 2

should read & send.

To receive call sudo video_gnd -n wifiinterface -c 200 -u N | tee output.txt to write to a text file. Adjust this to your needs

If the data rates are low enough some of the cheaper LoRa ESP32 modules could be a better choice. They are less complex, cheaper and will probably give you more range. Not sure if there is a ready to use firmware for your purpose.

Thanks, you are so kind. I will follow your instructions. Thank you again

I have tested your esp32 project and it works very well, but its UART speed is limit to 115200bps, so. .
