CC2340R5-Q1: Current behavior after Advertise transmission

sjmizuta

Part Number: CC2340R5-Q1
Other Parts Discussed in Thread: CC2340R5, SYSCONFIG

Hello TI Team.

I am currently testing the power consumption behavior by making changes only to the following parts of the "SDK: simplelink_lowpower_f3_sdk_7_40_00_64, SW: basic_ble_LP_EM_CC2340R5_freertos_ticlang".

　Device Role：Broadcaster

　Advertisement Parameters 1>>Legacy Event Properties Options：Non-connectable and Non-scannable undirected

...

The behavior that occurs approximately 700 milliseconds after transmitting the Advertise (3 channels) for a duration of 2.9 to 3.2 milliseconds is not clear without further context or information about the specific software or system being referred to.

To provide a more accurate answer, please provide additional details or specify the specific software, system, or context in which this behavior is happening.

Regards.

Hello,

Can you please reiterate what the problem is you are having? Are you asking about the area I highlighted in red?

Additionally, what exactly are you trying to understand about this section of the plot?

Let me know!

Thanks,

Isaac

Hi, Isaac.

Thank you for your response. Please proceed with your answer.

The part that I want to confirm is the portion enclosed in a red frame.

I am considering a system that operates CC2340 with a coin cell battery and I am aiming for further power efficiency.

Understood. In order to understand whether that particular component is functioning as a software or hardware factor, as well as the specific purpose of its operation, you would like to gain a better understanding. This is important for the product review that will be conducted during the product release.

Regards, sjmizuta.

Hello,

I am currently looking into the question further, please expect a response on Friday.

In the meantime, is your project crystaless? This could extend the RX window after advertising.

Let me know!

Isaac

Hello,

The time area specified is post processing, this then goes to standby. Please refer to the image below.

This image shows what is happening within each section of the current plot. The image shown doesn't exactly match your setup, but the state analysis is the same.

If you want to take a closer look at this, please refer to the Measuring Current Consumption App Note, figure 6-14.

Sorry for the delay of this answer.

Please let me know if this answers your question!

Thanks,

Isaac
