Sandbox for FPV experiments. Telegram-group: `https://t.me/+BMyMoolVOpkzNWUy` | [link](https://t.me/+BMyMoolVOpkzNWUy)## News
* `26.07.2023` - FPV link setup via 4G modem .* `01.07.2023` - A short note about the imx335 gk7205v300 camera . About baud for telemetry .
* `22.06.2023` - Finally, the problem with the picture being jerky at 30fps was resolved .
* `06.04.2023` - Added coupler firmware for ivg-g2s with u-boot on board.
* `05.04.2023` - Added functionality to rcjoystick for displaying packet losses (link quality) in rssi.
* `04.04.2023` - OpenIPC has added the majestic streamer, now the ivg-g2s camera runs h265 cbr (constant bitrate). This gave a cleaner picture and a significant reduction in noise. At the same time, changes were made to the link launch process. The main service is now S98datalinkwith the config /etc/datalink.conf, and wfb is now launched via /usr/bin/wifibroadcast. The articles have been corrected to accommodate this innovation.
* `01.04.2023` - Due to certain circumstances, wfb-ng was replaced in my camera and recorder with an alternative from OpenHD . Here is the package for assembly in buildroot OpenIPC. The shell wrappers take into account both options, due to the presence of a parameter link_idthat is not required in the OpenHD implementation. Archive with binaries of both options.
