RTK-Surveyor has no Bluetooth light

I am having an issue connecting to my RTK-Surveyor.

When I power on the device I am able to get the PPS light blinking but I am not able to connect via Bluetooth or WIFI. I have followed previous posts and haven’t gotten very far.

  1. when I plug USB in the ESP32 slot i get gibberish

  2. when I plug USB into the ZED slot I get a successful connection to u-center

The only indicators that I see is one dimly lit led on the 10cm indicator.

as far as switches and other things inside are concerned, I have had the device open but not recently and i haven’t ever modified the DIP switches.

the outside switches are both down (until i turn on the device to test) at which point i turn on the device but leave it in rover mode

Thanks for any assistance you might provide.

This is the serial output of the ESP:

rst:0x10 (RTCWDT_RTC_RESET),boot:0x13 (SPI_FAST_FLASH_BOOT)

Something has caused the ESP32 to loose its firmware. Please try loading the latest firmware using these instructions: https://docs.sparkfun.com/SparkFun_RTK_ … re_update/

If that fails, we’ll have you send the unit back and replace it.

Brilliant!

That worked.
