Troubleshooting- How to Set up VTX Table on Betaflight 4.1.X Firmware

Note：The contents of the vtxTable need to be set up manually only on Betaflight 4.1.X firmware, in the old version, there is no need to set up. The SmartAudio is not available if the vtxTable parameter has not been set on Betaflight 4.1.X. (Shown as the below pic)

Reason for setting up VtxTable

As of Betaflight 4.1.0, band/channel and power level information needed to control video transmitters is no longer hardcoded but stored in a new facility called vtxTable.

The contents of the vtxTable need to be set up manually. They need to match the hardware, local laws, and regulations, as well as user preferences.

How to set up VtxTable

In the CLI tab, input command: 

vtxtable bands 5
