Local WiFI OTA Update
Over-the-air (OTA) updates offer a convenient and efficient way to update your modules using WiFi connection without physically connecting it to your computer. In order to upload firmware, you have to update your Sinric Pro integration with ArduinoOTA support code.
Below example demonstrates how to use Switch sketch with ArduinoOTA support.

Serial.printf("\r\n[setupOTA]: Ready");
}
// setup function for SinricPro
void setupSinricPro() {
// add device to SinricPro
SinricProSwitch& mySwitch = SinricPro[SWITCH_ID];
// set callback function to device

SinricPro.begin(APP_KEY, APP_SECRET);

void setup() {
Serial.begin(BAUD_RATE); Serial.printf("\r\n\r\n");
setupWiFi();
setupSinricPro();
setupOTA();
}
void loop() {
ArduinoOTA.handle();
SinricPro.handle();
}
Once you flash above code, OTA server will start listening to OTA updates from Arduino IDE.
Next time, you can select the OTA host (SinricProOTATestDevice) instead of COM port.
