Ⅰ. Overview
1. Product Features
(1)The G16 series utilizes a Qualcomm 6nm processor and runs on the Android 13 (64-bit) embedded system, ensuring smooth operation and an open ecosystem capable of installing the vast majority of APPs available on the market. It features a new high-power, high-bandwidth 2.4/5.8 GHz dual-band wireless module supporting automatic frequency hopping and dynamic MCS (Modulation and Coding Scheme) adaptation, achieving a image/data transmission range of up to 30 km.
(2)The G16 supports a rich set of interfaces, including SIM card, USB, Type-C, and PPM ports, and provides an SDK development kit. It supports video overlay and is
compatible with mainstream flight controllers’ ground station software.
(3)It boasts a 7-inch industrial touchscreen with a 1920×1200 resolution and sunlight-readable display. The high screen-to-body ratio ensures clear visibility of real-time information even under direct sunlight.
(4)Equipped with a high-energy-density lithium-ion battery, the device delivers 9-10 hours of operation on a full charge. The consistent “wilderness survival” design
philosophy ensures you have no worries about the device’s reliability.
2. Main Uses and Applicable Scope
The G16 is suitable for video/image transmission (with optional camera), data transmission, and control of unmanned equipment such as helicopters, fixed-wing
aircraft, multi-rotor drones, unmanned vehicles, and unmanned boats.

① Quickly power- cycle the receiver four times. On the fourth cycle, it will automatically enter pairing mode, indicated by the blue light flashing rapidly.
② Open the Device Helper app on the remote controller, tap “Pairing” → Start Pairing, confirm the operation, and wait for the “Pairing Successful” message.
③ After successful pairing, the receiver’s blue light will remain steadily lit.
Note：During frequency pairing, keep the remote controller and receiver within 50 CM of each other.
10. Data Transmission and Image Transmission Connection
Receiver 1：GR01
According to the wiring diagram above, connect the SBUS+Data interface of the receiver to the SBUS+Data interface of the flight controller, and connect the Ethernet port of the receiver to the Ethernet port of the camera. (Note: Please refer to the corresponding manual for device power supply and other wiring connections.)
（1）Image Transmission
Taking the Skydroid C10 Pro as an example: after powering the camera and connecting it to the Ethernet port of the receiver, launch the Gimbal FPV app to view the video transmission image.
Download the Gimbal FPV app at:
http://file.skydroid.xin/SkydroidCameraFPV.apk
If a third-party camera is used, its IP address must be set to the 144 subnet (e.g., 192.168.144.XXX), and the gateway must be set to 192.168.144.11. Otherwise, image sharing to a computer will not be possible.
To set up the video stream:
Open Device Helper → Video View → tap the Settings button at the bottom → Video Stream Address → select Custom, then enter the camera’s RTSP pull address.
Note: The RTSP address for third-party cameras should be obtained from the manufacturer. The FLY Ground Station does not support gimbal control for third-party cameras.
If using FLY GCS, go to:
Common Settings → Other Settings → User Interface → Video Window → C10.
（2）Data Transmission
Taking Skydroid FLY GCS as an example: enter the ground station, click the upper-left corner to access the connection switching interface.
Select the “S2 + G12 + G20 + G30” combination and click to enter, then click “Connect”.
Note: If the connection fails, please check:
① Whether the serial port baud rate of the receiver matches the baud rate of the flight controller’s data transmission port (the S2 flight controller’s baud rate is
921600).
② Whether the wiring of the data transmission line is correct (RX should connect to TX, TX to RX; see Section 11: Image/Data Transmission Connection in this
document for details).
11. How to Display Data-Transmission and Image-Transmission on G16 Remote Controller and QGroundContro Ground Station
Connect the data transmission cable of the open-source flight controller to the data transmission port of the receiver. Taking the QGroundContro ground station (hereinafter referred to as QGC, current version V4.4.3 64-bit) as an example for reference connection, the download link for QGC is: http://qgroundcontrol.com.
Note: The S2 flight controller can only be used with the Skydroid FLY ground station; do not use QGC to connect to it.

（5）The flight controller’s data transmission has been successfully connected.
11.2 QGC Image-Transmission Settings
Taking the G16 remote controller with QGC ground station as an example for reference when connecting the C10PRO camera for image transmission (ensure the G16 Assistant background service is closed).
(1) Open QGC and click the Q icon in the top-left corner of QGC.
(2) In the pop-up window, select “Application Settings”.
(3) Click “General”.
(4) Change the Source (Video Source) to RTSP Video Stream.
(5) Enter the RTSP address of the network camera in the RTSP URL field.
C10PRO / Network Port Gimbal (requires connection to C10PRO) RTSP address: rtsp://192.168.144.108:554/stream=0
C12 Dual- Sensor:
rtsp://192.168.144.108:554/stream=1
rtsp://192.168.144.108:555/stream=2
C20: rtsp://192.168.144.108:554/main
Third- party cameras (only support stream- pulling display): after setting to Custom, enter the corresponding RTSP pull address in the field below.
Note: The camera’s IP subnet must be set to the 144 subnet.
(6) Check “Low Latency Mode”.
(7) Click the aircraft icon “Back” in the upper- left corner to return to the flight page.
(8) The flight controller’s image transmission has been successfully connected.
12. Diagram of Third-Party Flight Controller Connection
Diagram of Vectronics V9 Data Transmission Module Connected to GR01:
Note: This tutorial is based on using an open-source flight controller. If using a third-party flight controller, please consult the flight controller manufacturer to confirm whether this connection method is supported.
The steps to enable the hotspot on the remote controller are as follows:
(1) Method 1:
Open Settings → Network & Internet → Hotspot & Tethering → Wi- Fi Hotspot → Turn on “Use Wi- Fi Hotspot”, then connect the computer to the remote controller’s hotspot.
(2) Method 2:
Connect the computer’s Ethernet port to the remote controller’s Type- C port using an Ethernet cable. Then, open Settings → Network & Internet → Hotspot & Tethering → Turn on “Ethernet Tethering”.
(3) Method 3:
Connect the computer’s Type- A port to the remote controller’s Type- C port using an A- to- C data cable. Then, open Settings → Network & Internet → Hotspot &
Tethering → Turn on “USB Tethering”.
Note: The network connection on the computer side must be set to Obtain an IP address automatically, and the firewall should be disabled.
13.1 Sharing Data Transmission
After successfully connecting using any one of the above three methods, open “Mission Planner” and select TCP as the connection method.
After clicking “Connect”, enter the IP address 192.168.43.1, then click “OK”.
Enter the port number 5760 and click “OK” to establish the data transmission connection.
13.2 Sharing Image Transmission
After successfully connecting using any one of the three methods described above, launch VLC Media Player on your computer.
From the Media menu, select “Open Network Stream”, then enter the camera’s stream address as shown in the figure below. This will enable the date transmission
sharing.
Note: If using a third-party camera, you must set the camera’s gateway to 192.168.144.11 in order to share the image transmission.
