CC2651R3SIPA: BLE beacon

Koichiro Tashiro

Part Number: CC2651R3SIPA
Other Parts Discussed in Thread: CC2564MODN, CC2642R

Hi,

My customer is looking for BLE device and the usage is BLE beacon.

Q1) Do we have sample project for BLE beacon or similar scenario?

Q2) The customer wants to know power consumption for below two scenarios.
Do we have any data available?
Scenario a) CC2651R3SIPA receives BLE beacon
Scenario b) CC2651R3SIPA sends beacon with 10sec interval

Thanks and regards,
Koichiro Tashiro

    Hi Tashiro-san,

    Q1- Checking in the SDK, the simple_broadcaster example is not available for CC2651R3SIPA. However, it is available for the CC26x2, and the porting should be pretty straight forward. So I recommend you look into this example.
    I recommend you start the development from the simple_peripheral example for CC2651R3SIPA and leverage the simple_broadcaster for CC26x2 in order to tune the example to fit your requirements.

    Q2- You can leverage the Power Calculator to get a rough estimation of the power consumption achievable with the CC26xx. The calculator may not mention it supports CC2651RSIPA, but, it should remain pretty close.
    If more accurate estimation is required, I recommend you setup the example as suggested before and run tests using Energy Trace.

    I hope this will help,

    Best regards,

    Hi Clement,

    Thanks for your quick reply!
    Let me ask a few more questions.

    Q3) I checked the Power Calculator and there are BLE-Peripheral tab and BLE-Central tab.
    Which one is suitable to estimate beacon scenario?

    Q4) The Notes tab says below.

    It does not make sense to me why CC26X2 average current consumption is significantly higher, but the energy consumption differs less than 5%?

    Thanks and regards,
    Koichiro Tashiro

    You should use BLE-Peripheral tab is more suitable.

    The descriptions already explain the detatils about why CC26X2 average current consumption is significantly higher, but the energy consumption differs less than 5%

    Hi YiKai,

    Thanks for your reply. I understood.
    I tried to modify BLE-Peripheral tab and estimate power consumption.
    As customer used cc2564modn in previous product and concerns power consumption differences,
    I tried to use advertising scenario below from cc2564modn datasheet.


    What I got from Power Calculator with below configuration is only 16uA for Legacy Advertising.


    It is very small compared to cc2564modn. Is this reasonable?

    Thanks and regards,

    I think it's reasonable since CC2642R is more state of the art and dedicated to BLE application.
