RESET Button | Restart the P8 Module |
CONFIG Button | Pressing it alone is not defined. Press and hold the CONFIG and RESET Key at the same time. Release the RESET key first, and then release the CONFIG key to enter the configuration state. |
Power Requirement
Mount the antenna to the P8 before connecting power. Both the sky terminal and the ground terminal need to use an independent power supply instead of obtaining power from the controller. Please ensure that the maximum output current of the power supply is >2.5A (3~6s battery is recommended).
Default Configuration
Connect Controller
Use a special cable to connect the flight control interface [TELEM1]/[TELEM2] (some flight control interfaces are called Module), and the P8[Data] interface.
Ground Station Connection
Mission Planner
After connecting to the P8, select the correct port in the upper-right corner of the ground station, select 57600 baud rate, and click [CONNECT] to CONNECT to the ground station.
Port not recognized? After the P8 is connected, the mouse moves randomly and cannot communicate? Does the digital transmission indicator turn off and not work? For more information, please see FAQ]
QGroundControl
After data transmission is connected, open the QGroundControl and the ground station will automatically identify and connect. If it is not identified, you can manually add it as follows.
Click the icon in [QGroundControl]-[communication connection]-[add]
In the following interface, enter [name] [type] [serial port] and [baud rate], and click OK.
Select the connection you just added and Click Connect.

FAQ
Port is not recognized after connected to the computer?
Please install the Module driver。
After connecting, the mouse moves and cannot communicate. What’s the matter?
Please power the Ground Unit first, and then power the sky Unit. If the data at the other end is transmitted to the USB when the USB is started, the computer will automatically install the Microsoft mouse driver.
Sometimes the P8 indicator will turn off does not work?
Please make sure that the maximum current input at the power port is greater than 2A; Otherwise, the P8 may be stopped; It is recommended that the ground unit use independent power supply instead of flight control power supply (connect V5 + flight control can not use independent power supply).
