Detailed Description

EspNowUnicast.ino demonstrates how to transmit unicast ESP-NOW messages with WifiEspNow . You need two ESP8266 or ESP32 devices to run this example.

Unicast communication requires the sender to specify the MAC address of the recipient. Thus, you must modify this program for each device.

The recommended workflow is:

• 1. Flash the program onto device A.
• 2. Run the program on device A, look at serial console for its MAC address.
• 3. Copy the MAC address of device A, paste it in the PEER variable below.
• 4. Flash the program that contains A's MAC address onto device B.
• 5. Run the program on device A, look at serial console for its MAC address.
• 6. Copy the MAC address of device B, paste it in the PEER variable below.
• 7. Flash the program that contains B's MAC address onto device A.
