SparkFun RTK EVK Unit Stuck in a Loop After Updating d1.5

GPS/GNSS
1

standard version wouldn’t work for transmitting signals via NTRIP. I just updated to version d1.5, but now the unit seems to be stuck in some sort of loop. It just keeps displaying the SparkFun logo with the firmware version on the screen, then it shows “Configure VIA ETHERNET STARTING” and “GETTING IP.” After that, it restarts and goes through the same sequence all over again.

Thank you for reporting! This is a known issue. We’re working on it. Please use production releases (v1.4) for now.

thanks

How can I perform a downgrade?
First, I modified the configuration files in SFE_EVK_Settings_0.txt to enable access, connected the device via ESP32, and tried loading RTK_Everywhere_Firmware_v1_4.bin through the terminal. However, I encountered this error:

Loading RTK_Everywhere_Firmware_v1_4.bin
ERROR - Failed to allocate firmwareFile

Docs here. I recommend the GUI method.

Update:
I selected a Baud Rate of 115200 for this model.

After a few minutes, I successfully rolled back my RTK EVK to version 1.4.

However, to data transmission via NTRIP to work and to save configurations through the web UI, we should install version d1.4.

Sorry for the hassle! We are aware of the NTRIP not saving through the Web config. Until we get a v1.4 release complete, please use the serial configuration interface to set the NTRIP parameters.
