Hi Praveen,
Thank you.
I can now see the same issue:
Previously, I did not have an SD card inserted. I see the error now, after inserting an SD card.
I think the ESP32 is running out of RAM. The SD task is using some extra RAM and this causes the WiFi task to fail. If I disable Bluetooth to save RAM, the unit is able to connect to WiFi and I can use PuTTY to view the NMEA data.
Please try replicating this to confirm this is the issue:
Disable Bluetooth:
s b b
You should see “b) Set Bluetooth Mode: Off” in the System Menu
Exit the menu (this saves the settings):
x x
Then force a system reset with:
s d r
RAM use on the Reference Station is on a “knife edge”. We know there is not enough RAM to run ESP-Now and Bluetooth simultaneously. I think in your case, enabling TCP Server is using additional RAM and preventing WiFi from working…
Thank you,
Paul
