Heltec Wifi Kit 8 UART Struggle
Posted: Fri Sep 28, 2018 7:47 amI am using the Heltec Wifi Kit 8 and am attempting to connect an Adafruit UltimateGPS module and their documentation (https://cdn-learn.adafruit.com/download ... te-gps.pdf) shows on page 13 how you can verify you have wired correctly to a Arduino board. I have connected the GPS module to TXD0 & RXD0
(see https://www.bing.com/images/search?view ... ajaxhist=0)
I have followed the instructions in the Adafruit documentation and I have verified I can see the NMEA messages on the Serial Monitor, so I know I have the GPS module wired correctly to the Heltec.
I have downloaded the TINYGPSPlus.h library and am attempting to get the "Full Device" example to work.
My problem is I always get the "No GPS detected: check wiring." message.
I have set the GPSBaud to 9600 the default value of the Adafruit GPS board and I have used various values shown on the pinout diagram for the RXPin and TXPin values, but I always see the "No GPS detected: check wiring." message.
In the Arduino 1.8.7 application I have set the board value to "NodeMCU 1.0 (ESP 12E Module)".
Can anyone assist me in getting this example to work?
Thanks in adavance
