: Newer firmware versions (V3.5+) use an updated diversity algorithm that actively searches for the strongest signal to provide smoother transitions between antennas, often compared to Clear View performance [2, 12, 13].
If you are currently troubleshooting a specific issue with your setup, let me know:
Select the correct COM port corresponding to your connected module. If no COM port appears, you may need to install the Virtual COM Port (VCP) drivers from STMicroelectronics or Silabs.
Every firmware update a full recalibration to ensure the diversity algorithm accurately compares signals from both antennas. Setup : Remove all antennas from the module.
An FPV diversity receiver does not simply merge two signals together. It uses a microscopic processing unit to evaluate the signal strength (RSSI) of two separate antennas—typically a directional patch antenna and an omnidirectional pagoda or cloverleaf antenna—and switches to the cleanest source in real time. Updating your Furious FPV True-D firmware directly impacts:
Once you flash Pirx, you cannot go back to official firmware without repeating the UART flashing process.
For standard True-D modules, you will need a micro-USB cable, a PC, and the official Furious FPV firmware updater tool.
