>How to Connect to P-70 Ultra via Bluetooth BLE< |
|
The P-70 Ultra has two hardware Bluetooth BLE channels, both compliant with the
Bluetooth 5.1 specification.
Channel 1 Bluetooth name: "P-70 Ultra NTRIP BLE" (20 characters total).
Channel 2 Bluetooth name: "P-70 Ultra BLE" (14 characters total).
If your app is designed to support the NTRIP protocol, connect through Channel
1.
If your app does not support NTRIP, connect through Channel 2. |
|
Each Bluetooth channel uses a main UUID of "FFF0", and Characteristic 1 UUID is
"0xFFF1", which supports: "Notify, Write Without Response".
The downlink data on this UUID port is "NMEA 0183 Version 4.11" messages.
Your app only needs to access the "0xFFF1" port.
Note: Channel 1 supports uplink data in "RTCM 3" message format; Channel 2 does
not support uplink data. |

Below are examples for two mainstream operating systems, demonstrating how to
connect and test Bluetooth BLE using the LightBlue App. |
