best TI platform for direct radio control of basic rate bluetooth

Other Parts Discussed in Thread: CC2400, CC2560, CC2564

Greetings, TI,

I would like to build my own physical-layer driver accessing basic-rate bluetooth packets.  I'm basing my prior knowledge on the CC2400 transceiver, which is apparently deprecated.  However, this part has features that I'm looking for:  register-level transceiver physical layer control.  I'd like to ask what might be the recommended TI migration path?  And if you can recommend such a part, would there be an integrated processor/radio eval board for it?

Summary of what I'd like:

(1.)  supports basic-rate bluetooth physical layer (1 MHz channels, 1 Mbps baudrate, GFSK).  NOT BLE or Zigbee, thanks.

(2.)  direct radio control like the CC2400 via register r/w, perhaps fifo/spi output or any equivalent.

(3.)  NOT a high-level black-box interface like Bluetopia/CC2564x.

Thank you!

    Hi,

    Are you looking for a direct controlled "Bluetooth Classic" radio? The closest I can think of is the CC2560 or maybe even the CC2564. 

    Would one of these solutions help?

    Regards,

    Rafael

    It is likely that the 256x family can be made to solve my problem.  But, from what I've seen, it can only be addressed through the Bluetopia software interface, which is complex to the point of being incomprehensible in a short time period.  All I want to do is get a transceiver into basic rate demodulation and sending the raw bits across to a processor.

    If there is a simple Bluetopia mode that does that, I'm interested!

    Thanks again.

    Hi,

    Please apologize for the delay; this thread slipped under my radar. I am not aware of such solutions but I notified the group that can provide further clarifications.

    Regards,

    The CC2564x devices have inbuilt BT Link control and LMP processing incorporated. The external device can only communicate through HCI protocol. There is no interface to directly communicate with the BT PHY.

    Thanks

    Thank you for confirming.  That was what I understood from searching the TI solutions.

    May I add this question (might need to go to a different forum?):  will the 2400 continue to be a TI product line?  That transceiver does PHY layer at 1 Mbps as I require, but the claim is that the part is being deprecated.

    Thank you.
