I just got a pair of stock Heltec Lora v3 boards and they work fine with GPS info from Bluetooth connected smartphones.
I’d like to use the heltec without the phone and add a ublox neo6 compatible GPS module.
My question is : using the already compiled and installed firmware , which heltec pins should I solder the GPS TX and RX leads to?
Also, where are the pin assignments defined in the src? I looked in configuration.h but didn’t see anything.
Many thanks for reading and hopefully answering…
