-Никаких дополнительных настроек для wfb_tx пока не вынесено в конфиг, для тестов их можно добавлять в функции start_wfb в скрипте инициализации /etc/init.d/S98wfb

+Включается в /etc/wfb.conf, настройки в /etc/telemetry.conf
+
+Важно! Для работы телеметрии, придется экспериментировать с выделением памяти для системы. Отключить ВСЕ не нужное в камере кроме основного потока, проверить сколько свободной памяти осталось после выделения видео подсистеме и передать свободную в OS. (для GK7205v300: fw_setenv osmem 64M)
