>How to Connect via Bluetooth to a Windows PC<

Using "Windows" as an Example

Connect the P-70 Ultra to a power source.

If using a power bank, activate the low-current mode first to prevent automatic shutdown during use.

Go to "Settings" - "Bluetooth & devices", turn on Bluetooth, and click "Add device".

  Click "Bluetooth".

  Click "Show all devices".

  In the list of discovered Bluetooth devices:
• "P-70 Ultra NTRIP SPP" is Bluetooth Channel 1. If you need to provide NTRIP data service for the P-70 Ultra, please select this channel.
• "P-70 Ultra SPP" is Bluetooth Channel 2. If the P-70 Ultra is already receiving NTRIP service through another method and you only need to obtain position data, please select this channel.

  Select your desired Bluetooth channel, and the system will display "Your device is ready to go!".

Open "Device Manager" - "Ports (COM & LPT)". Each Bluetooth channel will generate a pair of COM ports.
Only one of these ports can be used for connection. In your application software, try connecting to different ports. When the connection is successful, the Bluetooth indicator will light up, confirming that the Bluetooth connection has been successfully established.

Different computers generate different port numbers, and the screenshot is for reference only. Please refer to the actual port number. When using a Bluetooth port, there is no need to manually set the baud rate.
