How factory reset Torch without menu?

GPS/GNSS Enclosed Products

I unwisely turned on the output of NMEA sentences to the serial port and now I can’t use that port to access the serial configuration menu. My guess is that a factory reset will fix my problem, but how do I do a factory reset if I can’t use the serial port?

When I start the Torch I see the following at the serial port. It’s not responding to me hitting the Enter key.

Hi Jim,

You need to send “+++” to exit the output-GNSS-data-over-USB mode. It is in the docs, but well hidden:

https://docs.sparkfun.com/SparkFun_RTK_ … enu_ports/

(Scroll down to the end of “Output GNSS Data over USB”)

Please let us know if the docs need to be made clearer - or if the firmware should print instructions when going into this mode.

Best wishes,

Paul

Paul,

Thank you, that worked great. I got focused on how to do a factory reset and didn’t see the “+++” entry in the documentation. It might be a little easier to find it if the sentence “To exit this mode, press +++ to open the configuration menu.” came before the image with the caption “Example NMEA output over USB”.

I like the idea of adding a note that’s printed by the firmware after the Output GNSS data to USB serial option is enabled. The sentence describing “+++” in the documentation would work well.

Jim, you can also double tap the button on the Torch to put it in Wi-Fi config mode (two beeps in response); it’ll make an AP titled “RTK Config” and serve a webpage with all of the basic settings from the serial menu.
