@@ -4,3 +4,6 @@ This is a manual test application for the NRF802154 radio driver.
 # Usage
 For testing the radio driver you can use the ifconfig and txtsnd shell commands
 that are included in this application.
+
+For testing beacon frame acceptance you can flash this test onto two nrf52 devices
+and use the send command to send a beacon frame. The opponent should print the received frame details.
