Title: RFM69 Rx and Tx at the same time
Post by: mafiat on May 07, 2016, 12:47:15 AM

Hi all,

I am new to RFM69 and have a question and need help. Is there a way to receive and transmit at the same time on a RFM69 Module? I am trying to build a irrigation system and want to receive info from the irrigation system and at the same time command the irrigation system.

Appreciate your help.

EXACTLY the 'same time', no.  Can a node support both send and receive?  Yes, absolutely. 

Communication is half duplex - there is one transmitter and one or more receivers at any one instant on the same frequency.  Each node, however, can change roles between transmitting and receiving.  This is a typical Moteino configuration.

The RFM69 library includes several examples in its distribution.
