CC2640R2F: Deep sleep mode, or configuring multi mode in single chip

Prakash S20

Part Number: CC2640R2F

Dear All,

I am LAUNCHXL_CC2640R2F evaluation module; later, I need to customize my own custom board. Now I know to create the custom profile and send the data I got from the ADC of this module itself.

Actually, I need to develop the code so that it should consume very little power from the source.

Below I have listed the operations that need to perform.

1) Sensing and store the data in a local array

2) Deep sleep for some time and initiate the next sensing

this process will repeat up to some "n-th" data; after that, send the complete data through Bluetooth to the other BLE modules. After this, again repeating the same process of 1 and 2.

I may be vague, but I want to convey that the RF portion should not be activated during the sensing time. Once the complete sensing is done, the RF portion is purposefully turned ON to send the data through Bluetooth.

Please let me know that how I can able to configure as I mentioned.

Thank you,

Prakash S

I suggest you to implement your application based on simple_peripheral example which already enable power saving by default.

Prakash,

I will assign someone who will be able to provide feedback. What SDK version are you using or planning to use?

Dear Chen,

I am already using a simple peripheral project only. Is it like that it can optimize power consumption as per the operations?

Thank you,

Dear Luis,

I am using this version "simplelink_cc2640r2_sdk_4_40_00_10".

Thank you,

Yes, I see no problem to do what you mentioned in your original post and you can also consider to use sensor controller to do this.

Hi Prakash,

I recommend you keep using the simple_peripheral example. This example is already optimized for low power operations.
