6.1.1 RTK connection
The RTK receiver is the core peripheral of the Trion Survey application, providing centimeter-level positioning services. The connection process is as follows:
1. Select [Settings] → [Connection], select RTK as the device type, select Bluetooth or Wi-Fi as the connection mode, select the receiver identification code (distinguished by the last 5 digits of the SN number) in the device list, and click [CONNECT]. When connecting for the first time, Bluetooth will have a pairing code, and the Wi-Fi password is 12345678.
2. If the receiver is not displayed in the list, please check the device power status and whether the communication mode is enabled, or manually click the Refresh button to update the available device list;
3. Automatically returns to the homepage after successful connection.
Note:
Check the SN number of the receiver at the bottom of the device. If it cannot be connected, try restarting the receiver or deleting the paired Bluetooth or Wi-Fi device in the Android system and reconnecting.
