• Master
  • Slave

  • The slave device(s) broadcast an access-point (AP)
  • The master device scans for the AP and adds the slave device(s) into its peer list
  • Callbacks are set, on each device, to send and receive data
  • The master reads data from digital IR sensor and sends that data to slave(s)
  • The slave device receives this data to turn on the LED and Buzzer connected to it.

  • Just download the repository or copy the code from these files and upload it to their respective devices.
  • To incoporate more than 1 slave device, upload the slave code to other ESPs
  • Make suitable changes to the master program so that each device in its peer list is sent data
