Arduino libraries and example to use with mosquitto mqtt (PubSubClient) and Sim800/900.

This sketch code to get geolocation with SIM900 & Gps NEO-6M and send the coordinates to a API.

Simple GSM shield Manager for Blynk and ESP32 / ESP8266 boards, with or without SSL, configuration data saved in SPIFFS / EEPROM. This library enables user to include both Blynk GSM/GPRS and WiFi libraries in one sketch, run both WiFi and GSM/GPRS simultaneously, or select one to use at runtime after reboot.

How to send a GET and POST request with GSM/GPRS module. This is useful for retrieving data from the Web and sending data to a web server. Tested on SIM900, SIM7000e, SIM800L GSM modules. Could work with other GSM modules that are operated by AT commands

Library, now using AsyncWebServer instead of (ESP8266)WebServer, for enabling GSM/GPRS and WiFi running simultaneously as well as configuring/auto(re)connecting at runtime GSM shields to Internet and Blynk and ESP8266/ESP32 WiFi modules to best or available MultiWiFi APs and MultiBlynk servers. Enable adding dynamic custom parameters from sketch…

A much more comprehensive library for Arduino SIM900 shield.
