Wireless Network Connection Using TRF7970A

Other Parts Discussed in Thread: TRF7970A, RF430CL330H

I would like to use the TRF7970A to aid in connecting a ZigBee network. I know it would work similarly to the Bluetooth connection examples with the NFC chip reading the ZigBee network ID but I am unsure how to send this ID to the microcontroller.

    Hey Rachael,

    Do you want to use a smart phone as an intermediary or just node-to-node sharing?

    For Node-to-node, your best option is using the TRF7970A in Peer 2 peer (P2P) mode. P2P mode allows both nodes to send information back and forth, so this would allow them to exchange their ID's.

    We have a P2P TI Design: www.ti.com/.../TIDM-NFC-P2P;tisearch=tidesigns

    But I would recommend using this code base which has Card Emulaation (CE) and P2P modes. It's updated and on a less expensive hardware. (also originally based on P2P app note.): www.ti.com/.../TIDM-NFC-CE;tisearch=tidesigns

    For using the Phone as an intermediary, you could us the RF430CL330H. This chip is a dynamic tag, which the phone can read & write. Your host controller would write the ID into the RF430CL330H, and the phone would read it out. Then the phone could write it into the next node, or multiple nodes, that need that ID.

    Which sounds best for your application?

    Thanks,
    JD

    John,

    This is exactly what sort of input I was looking for, thank you. Right now, I'm looking at node-to-node sharing. But I'm glad to have the information on using the phone as well.

    Thanks again,

    Rachael
