Problem sending GPS Data from TTGO T-Call (ESP32) board to Thingspeak using integrated SIM800L.

23 visualizaciones (últimos 30 días)
I am working on a project to send GPS data from a Neo 6M GPS module connected to TTGO board, to Thingspeak and Blynk using the SIM800L module on the TTGO. For this i have combined two sketches avaiable on the internet.(Thank you to original coders)
  1. The first sketch sends GPS Data to Blynk using SIM800L. (Using ESP32 TTGO board)
  2. The second sketch sends GPS data to Thingspeak via Wifi. (Using ESP8266)
So I combined the two sketches with a bit of editing to achieve what i want. However, the code is not compiling and unable to upload to the TTGO board. I am sure in the cut and paste of sketches i might have made some errors. I am just a newbie and just tinkering with the code.
The error is : no matching function for call to 'ThingSpeakClass::begin(ThingSpeakClass&)'
Can anyone please point out the error and correct it. Thanks

Try to strip down the example to the minimum to find the source of your issue. Since this is a build issue, I suspect your toolchain is not set up correctly.
