如何设计高效抗干扰的无线通信协议
分享资料个
This application note describes the low-level Frequency Agility Protocol for nRF24XX. This
is a protocol that gives protection against disturbing traffic from frequency stationary systems
like WLAN and frequency hopping devices like Bluetooth.
The protocol is generic and can be used in many different systems that require resistance
against disturbance from other systems. By using this protocol， a system can operate in close
proximity with systems using different WLAN channels， 2，4GHz cordless phones， 2，4GHz
remote controls， microwave ovens， Bluetooth devices and other proprietary 2，4GHz systems.
Basing its functionality on recovery by retransmission of lost packets， it will be much more
reliable than a uni-directional communication protocol.
This document describes the assumptions that the protocol is based on， a description of the
functionality， implementation described with state machine diagrams， current consumption
calculations and C-code examples.
