Suggestion for RF Radio Transceiver having 1 Mbps or above radio baud rate capability

Other Parts Discussed in Thread: CC1101, CC2500, CC2540, CC2541

Dear All,

I'm looking for a radio transceiver having ISM band of 2.4 GHz. I've a product with CC1101 radio (sub 1GHz) and want to upgrade it to 2.4 GHz band.

Radio transceiver for 2.4GHz should have:

  • At least 1 Mbps radio baud rate 
  • It should give direct access to radio root registers to play with it internal configurations (like CC1101).

I've have seen CC2500 radio transceiver, its look good for me but it has a 500kbps baud rate.

RF radio transceivers will be preferred instead of RF radio SOC type(Wireless MCU) until unless they provide root access to their radio RF registers.

Thank you.

    Hi Hassaan,

    All of the CC254x devices, except CC2540, supports up to 2 Mbps GFSK and provide access to all radio registers.

    Cheers,
    Fredrik

    Dear Fredrik K,

    Your suggested RF radio series does not give us option for variable radio baud rate[250 Kbps, 500 Kbps, 1 Mbps or 2 Mbps only] like in case of CC2500[1.2 Kbps - 500 Kbps]

    [Issue 1] Can I use external Microcontroller like Arduino or STM32 to access RF radio register Only without using the on board  Microcontroller capabilities on CC254X devices. 

    [Issue 2] As i am unable to find relevant examples? can you point to any source.

    [Issue 3] Do CC254X supports Carrier Sense(CS) or Channel Clear Assesment(CCA) capability i cant find it in Datasheet or User Guide.

    Thank you.

    regards,

    Hassaan

    This is the second listed feature on the front page of the CC2541 datasheet: "Supports 250-kbps, 500-kbps, 1-Mbps, 2- 256-KB Mbps Data Rates"

    No. You can only access the registers through the onboard 8051 controller.

    Not directly, you would have to implement this yourself.

    Dear Fredrik K,
    Thanks for your prompt reply

    " This is the second listed feature on the front page of the CC2541 datasheet: "Supports 250-kbps, 500-kbps, 1-Mbps, 2- 256-KB Mbps Data Rates "

    [1] yes we know that CC254X supports these Radio baud rates but we want variable baud rates like 150 Kbps, 1.3 Mbps,1.7 Mbps
    [2] Can we also change Frequency Deviation value other than 160,250,320 and 500 Khz
