/*
 * Example for how to use SinricPro Doorbell device:
 * - setup a doorbell device
 * - send event to sinricPro server if button is pressed
 * 
 * If you encounter any issues:
 * - check the readme.md at https://github.com/sinricpro/esp8266-esp32-sdk/blob/master/README.md
 * - ensure all dependent libraries are installed
 *   - see https://github.com/sinricpro/esp8266-esp32-sdk/blob/master/README.md#arduinoide
 *   - see https://github.com/sinricpro/esp8266-esp32-sdk/blob/master/README.md#dependencies
 * - open serial monitor and check whats happening
 * - check full user documentation at https://sinricpro.github.io/esp8266-esp32-sdk
 * - visit https://github.com/sinricpro/esp8266-esp32-sdk/issues and check for existing issues or open a new one

SinricProDoorbell&&myDoorbell = SinricPro[DOORBELL_ID];

There must be just one &!

[sivar2311]

The reason is the second ampersand character.

Same error

[sivar2311]

Change SinricProDoorbell&&myDoorbell = SinricPro[DOORBELL_ID]; to SinricProDorbell& myDoorBell=SinricPro[DOORBELL_ID];

Just one "&" not two!
