Network Configuration

AP FPV stores Wi-Fi settings in the boot environment. Change them over UART or SSH, then reboot the VTX.

Change SSID and password

fw_setenv wlanssid VTX
fw_setenv wlanpass openipcfpv

Replace VTX with the desired network name and openipcfpv with the desired password.

Change Wi-Fi frequency

fw_setenv wlanfreq 5700

Set a valid 2.4 GHz or 5 GHz frequency supported by the Wi-Fi adapter and local regulations.

Change transmit power

fw_setenv wlanpwr 2000

Caution

Be careful with transmit power. Excessive values can overheat or damage hardware, violate local regulations, or reduce link quality.

Apply changes

Reboot after changing environment variables:

reboot

Mental model

Think of AP FPV like this:

• VTX: Wi-Fi access point and video source, usually 192.168.0.1.
• Ground station: receiver device, often 192.168.0.10.
• Video stream: RTP/UDP data from VTX to receiver.
• Web UI: camera control page at http://192.168.0.1.
