Update:

  1. The VRX now supports 720P output via the HDMI port, enabling compatibility with Fat Shark FPV goggles (such as Dominator HD3 and V3).

Notes:

  1. For devices running firmware in the v1.0.x or v2.0.x series, please rename the firmware file after downloading it to include the specific ground unit model name; otherwise, the SD card upgrade process will not recognize the file. Please refer to the examples below for the correct naming format.

    VR04 should be renamed to: P1_GND_VR04_v2.1.3_20260825_7bad614.img
    VR04 Pro should be renamed to: P1_GND_VR04_PRO_v2.1.3_20260825_7bad614.img
    Monitor should be renamed to: P1_GND_MONITOR_v2.1.3_20260825_7bad614.img
    VRX should be renamed to: P1_GND_VRX_v2.1.3_20260825_7bad614.img

  2. For devices running firmware in the v2.1.x series, no renaming of the firmware file is required when performing an upgrade.

 

Please confirm whether the device is beta test version or the official version.

Official P1 VRX Nano

The official version ships with firmwareV2.1.4. If there is no image after connecting to Dominator HD3/V3 goggles, switch the HDMI output resolution to 720P for proper operation.

How to switch:

  1. With an image displayed normally, simultaneously hold the 5D button in the down direction and press and hold the Back button on the receiver for more than 5 seconds, then release both.
  2. Wait for the device to restart automatically. The display will briefly go black while the output resolution changes.

  3. Repeat this procedure to toggle between 1080p and 720p output.

BETA TEST P1 VRX Nano

The Beta Test version ships with firmware V2.0.8, which does not support 720p HDMI output. As a result, no image will appear when connected to Dominator HD3/V3 goggles before the firmware is updated.

To upgrade, connect the P1 VRX Nano to a 1080p display using a Mini HDMI to HDMI cable. Confirm that an image is displayed, then follow the instructions below.

Firmware upgrade:

  1. Copy the firmware file to an SD card, then insert the card into the P1 VRX Nano.
  2. Navigate to Settings -> System -> System Upgrade -> Start Upgrade.
  3. Wait for the upgrade to complete successfully, then restart the device.

Notes:

  1. Follow the upgrade steps in the order listed to avoid an upgrade failure.
  2. The upgrade may take some time. Wait until it is complete before operating the device.
  3. Ensure the device has sufficient battery power before starting.
  4. Do not disconnect power during the upgrade.
  5. All settings will be reset after the upgrade. Reconfigure the device once the upgrade is complete.
  6. To upgrade only the air unit or only the ground station, copy only the firmware file for that device to the SD card.

After upgrading, you can switch between 1080p and 720p HDMI output to support goggles that require 720p input.

How to switch:

  1. With an image displayed normally, simultaneously hold the 5D button in the down direction and press and hold the Back button on the receiver for more than 5 seconds, then release both.
  2. Wait for the device to restart automatically. The display will briefly go black while the output resolution changes.
  3. Repeat this procedure to toggle between 1080p and 720p output.
