RF transmissionis not allowed while radio is set in Idle state.Receive StateIt is the normal default state. In this state the radio receives the RF packets, decodes the packets and sendsthem to the Host device. In this mode the transceiver checks continuously the RF signal and demodulatesit. The demodulated and filtered signal is sent to the microcontroller inside the radio module which
Author: Radio GroupDate: February 11th, 2014Revision: March 4th, 2015Subject: Integration Guide – Mizar Radio Module 915 MHzPage 8 of 10decodes it and sends decoded data to the Host by means of the UART interface. Only valid demodulateddata packets are sent to the Host.Transmission StateThis state is enabled from the host when it needs to transmit data. The transmission state is enabledsending a data packet to the radio module over the UART interface. The microcontroller in the radiomodule checks for the integrity of the data packet and enables the transceiver to modulate and transmit tothe RF interface, preceded by a short preamble burst. Radio module exits automatically from this statewhen the complete packet has been transmitted, and returns to the receive state.Radio module operates in CSMA-CA (carrier sense multiple access – collision avoidance) : transmission isenabled when the RF channel is not busy by the use of a “carrier detect” function. Radio module accessesthe channel in a fair way using a backoff algorithm.Interface description (pinout reference)UART 2-pin interface, used to exchange data from the Host:DATA_OUT (output pin) : transmits data to Host.DATA_IN (input pin) : receives data from Host.CD# – (output pin) Carrier Detect :When radio is in receive mode, this pin signals the presence of RF carrier.IDLE - (input pin) :A high level on this pin forces the radio module in Idle State.RESET (input pin) :A low level on this pin resets the radio module.VCC and GND :Radio module power supply.RF Port :Radio Frequency Connector for the antenna.
