Please use the parameter configuration board to check.
More operation guide for the parameter configuaration board, Jaki vea https://ivcan.com/parameter-configuration-panel-quick-operation-guide/
- Keep the antenna as high as possible because the ground absorbs the signal.
- Try to be at point B instead of point A. Because according to the transmission principle of the antenna, it propagates in an umbrella shape. The signal at point A is often very weak.
- The Transmitter frequency range can change to 1.4G or 1.34G.
- The receiver frequency range only supports 170-860Mhz, if you need 1.4G or 1.34G, you need to install a frequency down converter block at the receiver.
- We don't have the frequency down converter block now, maybe you can contact the below supplier. (Performance is much better than China supplier now)

From some UAV customers have measured 50km when they are testing, and the height of the UAV is about 300 metros.
- If the transmitter modifies the wireless parameters such as constellation, GI, CR, and BW, the receiver must be restarted to lock and display normally.
- Another possibility is that your transmitter modifies the constellation parameters through the AT command, but the parameters are not actually written into the baseband board. You need to restart the transmitter board to confirm.
- Our one-way cofdm video transmission is not designed to consider your current usage scenario (fast switching frequency).
- This may not work, the delay of TX switching frequency involves many aspects, such as the delay of the encoder board itself (currently the main program processes parameter changes in a cycle of about 1 segundo), and the processing delay of the baseband board, so add It takes about 2 second to switch. The processing delay of the encoder board can be squeezed to within 1 second by modifying the firmware, but the delay of the baseband board is not easy to squeeze, and the most important thing is that it is not easy to update the firmware (Da mengi ar fábrica pa utilizar ma equipo pa actualizar ar firmware).

- Because COFDM is a one-way transmission, both video and audio can only be transmitted in one direction. From the transmitter to the receiver, the audio cannot have a two-way intercom, just like an ordinary radio, which can only broadcast in one direction.
The UART command is here.
