Introduce
Collect record all data on TX / RX data stream to SD Card.
Users can then use those files for surveying and evaluating positioning.
SD Card driver on ESPrtk supports a variety of file formats, update cycles, NMEA filters, recording styles, etc.
This function can run as a parallel task with the main action on both Rover and Base.
This feature is only supported for the Wireless Bridge Rover and Wireless Bridge Base applications.

Configure:
File’s name:
Naming the file will store NMEA data. Maximum is 20 characters.
File format:
Supported file formats are “.log”, “.txt”, “.nmea”, “. nme”, “. gps”, “. ubx”, “. skt”, “. data”, “.dat”, “. bin”.
Recording type:
Suppose the file name is “my_test”. After restarting (by powering or pressing Reset button) ESPrtk will continue to write NMEA data.
- If “Append to old file” is selected: NMEA data will be added to the file with the fixed name “my_test”.
- If “Create and write on new file” is selected: ESPrtk will create a new file such as “my_test_2” and save the NMEA data into that file. On the next reboot, it will write to the file “my_test_3″…
Update cycle:
The update cycle only applies to Rover RTK (NTRIP Rover, MQTT Rover and Radio RTK Rover) when collecting NMEA information and does not apply to this case
Enable / Disable type NMEA :
