Folks,

The NTRIP server daemon tries to talk via WiFi and fails:

Base survey complete! RTCM now broadcasting.

Any help would be very appreciated,

It looks like the WiFi isn’t available at first but then successfully connects (status 3 is a good sign), so I suspect NTRIP is trying to use it before it’s fully initialized

What sketch are you running?

Hi Scott,

I’m wondering if this is a RAM issue. If you are not using Bluetooth, please disable it. It eats a lot of RAM… If you are using the Serial Interface, in the System Menu option b will cycle between Classic, BLE and Off. Fully exit the menu to save the changes, then restart.

I hope this helps,
Paul
