Part Number: CC2544

Hi, 

My customer has the following two question, please help to provide comments:

1. My customer have CC2544 and CC2640. One is programmed as Tx and the other one is programmed ad Rx.

     How much time does Rx need to wait for sending ACK after it got a packet from Tx ?

2. My customer have a plan to change channel  to avoid signal interference.

    How much time should I wait to change channel since I got data ?

  • Hi Mike,

    The Tx-Rx turn-around time in proprietary mode is around 250 us. 

    Regards,
    Fredrik

    Hi, Fredrik, 

    Regarding to the question "How much time should I wait to change channel since I got data ?", 

    Can my customer also reference the " Tx-Rx turn-around time in proprietary mode: around 250 us" to built his own  channel change mechanism ?
