We have a new library with RTOS support for ESP32:
Example for creating a background task for Thinger.io (notice the THINGER_FREE_RTOS define to enable RTOS functionality).
#define THINGER_SERIAL_DEBUG
#define THINGER_FREE_RTOS
#include <ThingerESP32.h>
#include "arduino_secrets.h"
ThingerESP32 thing(USERNAME, DEVICE_ID, DEVICE_CREDENTIAL);
void setup() {
// open serial for debugging
Serial.begin(115200);
pinMode(16, OUTPUT);
thing.add_wifi(SSID, SSID_PASSWORD);
// digital pin control example (i.e. turning on/off a light, a relay, configuring a parameter, etc)
thing["GPIO_16"] << digitalPin(16);
// resource output example (i.e. reading a sensor value)
thing["millis"] >> outputValue(millis());
// start thinger in its own task
thing.start();
// more details at http://docs.thinger.io/arduino/
}
void loop() {
// use loop as in normal Arduino Sketch
// use thing.lock() thing.unlock() if using variables exposed on thinger resources
}
