Request for nodemcu ESP12e board & neo 6m gps with thingsboard

[kfrancisg]

Hi, I am new to arduino as well as NodeMCU, I was trying to make a sketch for send gps data to thingsboard. I tried edit few code that were available. NodeMCU GPIO part is okay. But with GPS it seems like Thingsboard is not getting any telemetry data. `#include

include <TinyGPS++.h>

Sorry, if your issue is not related to SIM7000 them please don't post here. There are plenty of forums for ESP8266.
