Why is my TOP608BT connected via bluetooth, but no data transmission?

Posted by jack wu on

It could be because the bluetooth "protocol out" settings have been changed. The bluetooth module connects to the GNSS module by UART 2 port. baud rate is 38400 (bluetooth module baud rate has to be 38400). Please use U-center and update the UART2 port to the below values if they are not already with these values.

protocol in: RTCM3
protocol out: UBX+NMEA
baud rate: 38400
Form U-center menu, click View --> Configuration View (or the toolbar icon) and open the configuration view windows. Select UBX --> CFG --> PRT(Ports), Please refer to the below screenshot.
After changing the above settings, please save them permanently by following the below steps.
