Introduce .
This function allows users to collect NMEA data of RTK receivers via Bluetooth Classic while ESPrtk Rover is running.
This function is similar to Bluetooth to Serial., but only one-way transmission from ESPrtk. ( Only send NMEA from RTK receivers to Bluetooth device ).
There are no exceptions to the type of NMEA data, all of which are received and sent.
BLE Viewer on MQTT’s Rover.
BLE Viewer on NTRIP’s Rover.
BLE Viewer on WIFI-TCP or WIFI-UDP’s Rover.
To use it.
After restarting (power on or Reset), ESPrtk works as usual (receives RTCM from Base and stream out to TX-B (TX_UART1 or TX_UART2)), and collects all NMEA data from RX-A port (RX_UART1 or RX_UART2) and sends it to Bluetooth Client device. Now, just open your app , open Bluetooth and connect to ESPrtk to get data from GPS module.
During the operation, if Bluetooth Client disconnects the connection, ESPrtk will not report an error and the Bluetooth Client will be able to reconnect.
Sometimes reconnection needs patience and wait to connect successfully.
