RTK Surveyor: Empty NMEA Sentence from Data Port

Hi there,

I followed up the hookup guide to output data to an Embedded system (https://learn.sparkfun.com/tutorials/sp … leshooting) and ended up with nothing.

When I connect it to my pc using USB from esp32 port, I have got messages like:

Rover Accuracy (m): 429496.7187

I think the GPS unit is working even though the PAIR LED keeps blinking

When I use one of the Sparkfun FT232RL to output data to my pc, I can see /dev/ttyusb0 added to my serial port. But when I use screen /dev/ttyusb0/ 115200, it doesn’t display anything.

I tried to reset all settings to default, but still I cannot see my NMEA data.

The surveyor is set to Rover mode and during the time when power is on the PAIR LED is always flashing.

It seems to be busy waiting until the Bluetooth device is paired.

When I try to connect the surveyor using Bluetooth, it disconnects immediately after it is paired. And the PAIR LED keeps flashing during that process.

Sorry if it looks like a scatter of something. I need some ideas to solve this out.

Thank you,

Victor
