how to construct rfid network

sivasingaraj

I have worked with nrf24l01+ devices. In my project include single PRX with 100 PTX. Objective of this project is all PTX send packet to one common PRX device & PRX send ack to all PTX after get the packet. how can i create one rfid network between them. can i use tdma based solution.

thanks &regards sivasingaraj s

    Hi,

    ACKing is done by default, if you have not explicitly turned it off. You can also attach a payload to the ACK. Please see chapter 9 for details on which bits need to be set (see the FEATURE register). Note that this must then be set equal on both PRX and PTX.

    If two or more devices send at the exact same time, there will be an on-air collision, and most likely, no packets will be received. You will have to make some sort of protocol in firmware to handle this.

    Best regards Håkon
