LAUNCHXL-CC1350: Half Duplex Communication on CC1350

Part Number: LAUNCHXL-CC1350
Other Parts Discussed in Thread: CC1350,

Hello,

I am developing a product which transmits certain data wirelessly from a portable device to another device (Node - Concentrator Logic) for which I want to use CC1350 on my customized board. For study purpose, I have ordered CC1350 Launchpad and all the examples in CCS are given for either Transmitting or Receiving the data. 

I was wondering, is it possible to start a Half Duplex Communication using CC1350 launchpad which ultimately I can implement in my product.

Thank You

Keval Soni

    Hi,

    Half Duplex means that the Device is either in Transmit mode or in Receive mode at the same time but it may use different frequencies for Transmit and Receive operations. If this is what you want then it is possible with CC1350.

    Thanks,

    Hey PM,

    I have two concerns,

    1) When you say different frequencies, does that mean I have to make any hardware(RF Filter) changes in my customized board? 

    2) If no hardware changes are required, can you tell me how to do that in LAUNCHXL-CC1350 for study purpose?

    *Just Curious*

    Is there any way to start a full dulplex communication in LAUNCHXL-CC1350 ?

    Or to communicate with same frequency in Half duplex mode?

    Thank you

    Hi,

    1. No need to change any hardware to use different freqs for Tx and Rx. Make sure both Tx and Rx freq falls in the same band, for example ( 902 to 928MHz band in USA).

    2. Just use different freq for Tx and Rx.

    3. You need to use 2 separate boards for Full duplex communication. One for Transmitter ( operates on Tx Freq) and the other for Receiver (operates on Rx Freq)

    4. If you use same Freq for Tx and Rx, that is called Simplex Mode.

    What is your Application?

    Thanks,

    Half-duplex data transmission means that data can be transmitted in both directions on a signal carrier, but not at the same time. That is, no need to use different use different frequencies for RX and TX.
