I need to calculate RSSI, LQI, CCA from Zigbee RS232 RFM75 transceiver. I am transmitting data wirelessly from one arduino to another arduino via Zigbee RS232 RFM75 transceiver. So i need to calculate ther three metrics (RSSI, LQI, CCA) while transmitting data. Is there any library or inbuilt function for calculating these metrics. Please help me.
I have uploaded my transceivers picture.
Thanks in advance.
