CC1352P: CC1352P Evaluation board antenna

HARI T O1
Expert 1645 points
Part Number: CC1352P

Tool/software:

Dear Team,

This is a continuation of this question,which I asked earlier here.

In this project as I described in my previous question we will be connecting sensors to one of the TI CC1352P and from this data will be transmitted to another TI CC1352P which is almost 1Km way.The second CC1352P is connected to a PC

Qustion-1

So for showing proof of concept I need to buy two TI CC1352P boards.Please confirm.If you have any suggestions kindly know,I mean if we can show the Proff of concept  using 1 CC1352P board.

Question-2

Below is the board I selected.Could you please check this board is fine or not.

https://at.rs-online.com/web/p/entwicklungstools-microcontroller/2355155

if you have any suggestions please let me know.

Question-3

May I know do I need to purchase any separate antenna for this board or it contains integrated antenna.

If I need to buy external antenna could you please suggest the P/N.

Question-3

Could provide some examples or reference design using sub ghz communication using this.

I am a hardware person,my firmware engineer also have no experience in RF

Regards

HARI

    Hi Hari,

    If you have a new set of questions, please post them in one place rather than continuing the original thread and creating a new one - it is easier for us to track.

    1. Two boards are required, otherwise there is nothing to receive the transmitted signal. Do you have a target frequency band of operation? Different LaunchPad variations have different BOMs mounted depending on the target frequency band(s).
      1. The LAUNCHXL-CC1352P-1 has the BOM mounted for 868/915 MHz operation for the Sub-1 GHz RF path (and 868/915 MHz TX using the integrated +20 dBm PA).
      2. The LAUNCHXL-CC1352P-4 has the BOM mounted for 433 MHz operation for the Sub-1 GHz RF path.
    2. The board contains an integrated PCB antenna, so no additional purchase of an antenna is required.
    3. Please can you specify in more detail what you are looking for so we can point you in the right direction? The LaunchPads/reference designs are themselves what customers should use as a reference for the RF portion of their design. So, in effect, the LAUNCHXL-CC1352P-1 is the (RF) reference design. The design files for the LAUNCHXL-CC1352P-1 are found here, LAUNCHXL-CC1352P1 (SWRC349): https://www.ti.com/lit/zip/swrc349

    The other CC1352P design files, and more information on those LaunchPads, are found here: https://www.ti.com/tool/LAUNCHXL-CC1352P

    Regards,

    Hi Zack,

    Thank you very much.

    I will post all my remianing questions here.

    We have not selected the target frequency.

    Our sensor nodes will be situated upto a maximum distance of 1KM.

    In this case I believe 433Mhz will be better.Kindly share your thoughts about this.

    May I know at this frequency(433 Mhz) what data rate I can expect for a reliable communication at a distance of 1 KM?.

    Regards

    HARI

    Hi,

    You can use our RF Range Estimator for this:

    For 433 MHz operation you will need the LAUNCHXL-CC1352P-4

    Hi Zack,

    Thank you for the inputs.I will discuss with team and select the operating frequency.

    I have 2 questions.

    Qusetion-1:

    868/915 MHz: Ideal for Europe (868 MHz) and the Americas (915 MHz), with the +20 dBm PA supporting up to 5 km line-of-sight range at low data rates (e.g., 2.5 kbps).

    We are located in Europe.So I belive 868 Mhz needs to be used.Since inbulit PA is there I can obtain good range also.My maximum distance is 1 KM.

    So board is fixed. Slight smile

    CC1352P-1. The PA is in-built.May I know the P/N is LAUNCHXL-CC1352P-1 or LAUNCHXL-CC1352P1

    Also you have any user manual for this board?

    For the high-power Sub-1 GHz path (+20 dBm at 868/915 MHz), the board uses an external SMA connector (not the built-in antenna), allowing us to attach an external antenna for better gain.Please correct me If am wrong?If yes can you suggest some antennas for this.

    To the best of my knowledge, The board has a built-in PCB antenna for the low-power Sub-1 GHz and 2.4 GHz paths, with an approximate gain of 0 dBi.

    Please share your thoughts/Correct me if I am wrong

    Question-2:

    I am interfacing this gas sensor to the ADC of a TI CC1352P microcontroller. The datasheet of the Gas sensor does not mention anything about the interfacing.

    Can I connect the output of this gas sensor to this ADC through an RC low-pass filter (fc<100 Hz)?

    Question-3:

    May I know can I connect TI CC1352P with  Rosenbauer Connected command.

    https://www.rosenbauer.com/en/at/rosenbauer-world/products/software/operations-management/rds-connected-command

    Question-4:

    Is it possible to OTA in Sub-1 Ghz communication.

    Regards
