Abhishek Duivedi

Part Number: CC2642R

Few doubts regarding the Power calculation of BLE module and the power calculation tool link for CC2642 is BT-POWER-CALC. In this I am not able to get few points given below:

In BLE-Peripherals section:

  1. Advertising interval (ms)
  2. Advertising data length(legacy)(bytes)
  3. Advertising data length (extended advertising)
  4. Connection interval(ms)
  5. Connection data length (bytes)
  6. Scan response data length
  7. Crystal used

In BLE-Central section:

  1. Scanning Duration(ms)
  2. Scanning window (ms)
  3. Scanning interval (ms)
  4. Scanning type
  5. Connection interval(ms)
  6. Connection data length (bytes)

    Hey Abhishek,

    Thanks for posting on e2e. Can you please clarify your question? I am not exactly sure what you are asking here.

    If you are unsure what the configuration parameters are, these are Bluetooth LE specific settings that define the frequency that certain Bluetooth LE packets are sent over the air (advertising, scan response, connection packets). I would take a look at our SimpleLink Academy module for some high level guidance.

    Hi Ammar,
    Thank you for your respnse.

    For CC2642, there is one power calculation tool. Here is the link:

    https://www.ti.com/tool/BT-POWER-CALC

    When you download and exact the file. One excel workbook will be there and we just need to fill in few parameters to get the power consumption. So, I am unaware of few details. Like four sheet are available in this workbook.

    If you click  BLE-Peripherals section, There are few terms I am unaware of like:

    1. Advertising interval (ms)
    2. Advertising data length(legacy)(bytes)
    3. Advertising data length (extended advertising)
    4. Connection interval(ms)
    5. Connection data length (bytes)
    6. Scan response data length
    7. Crystal used

    Similarly, if you click on  BLE- Centrals section, there are few doubts I have:

    1. Scanning Duration(ms)
    2. Scanning window (ms)
    3. Scanning interval (ms)
    4. Scanning type
    5. Connection interval(ms)
    6. Connection data length (bytes)

    Can you please help me out with this?

    Hey Abhishek,

    These parameters are described in the Bluetooth LE fundamentals SimpleLink Academy, please take a look: dev.ti.com/.../node

    It is up to the application designer to define these parameters (advertising interval, payload information (i.e. advertising data length), connection interval), etc.
