I am trying to run an RTK Surveyor unit as a base station and it will get a fix, and transmit to another unit (Surveyor Express) via ESPNow radios. However, when I check the SD card after a session, the ubx file that it creates is empty (0 kb size and no data written to the file).
The SD card is a 16GB size and works correctly otherwise.
The surveyor Express unit I have will successfully write the log files to an SD card when it is in base mode.
Is there a setting I’ve missed? I thought I had the 2 units configured similarly when run as a base station.
…so, the Surveyor won’t log while in base mode?

Can you check your firmware version?
I did verify that logging to the SD card was enabled, and I have successfully captured a log file from this device in the past. The only thing that I’ve changed since that log file collection is that I’ve acquired a Surveyor Express and I had them in RTK mode using the ESPNOW radio communication.
It creates a log file, but doesn’t write any data to that file. I see a file name with a .ubx extension that I am expecting, but it is zero bytes and is completely blank.
I checked the firmware and I was on v4.0, and I just upgraded to v4.1 tonight. I’m going to test it again tomorrow afternoon.
I will probably use it as a rover tomorrow since the Express will reliably store a log file as a base station. I will also test the Surveyor as a base before I finish though to see if the firmware update changed anything.
