Dear TI members,

In this disccusion thread: CC2340R5: How to turn off RF signal - Bluetooth forum - Bluetooth®︎ - TI E2E support forums

In order to turn off BLE broadcast feature, TI suggests that if the device is not in a connection, then simply disabling scanning and advertising should cease all ble activity.

This can be done through the use of the BLEAppUtil_advStop() and BLEAppUtil_scanStop().

But I'm just wondering if we can remove BLEAppUtil_advStart(), BLEAppUtil_scanStart() instead? Does this make any sense?

The table below is my current building environment:

Software	Version
Code Composer Studio	12.4.0.202306011800
SimpleLink SDK	7.20.1.10
XDCtools	3.62.1.16_core

Thanks,

Zach

Hi Zach,

Thank you for reaching out.

Your are correct, not-calling BLEAppUtil_advStart() and BLEAppUtil_scanStart() should prevent the device to execute any RF operation.

For information, you can toggle some pins while the radio is active - see the procedure here: https://software-dl.ti.com/simplelink/esd/simplelink_lowpower_f3_sdk/7.40.00.64/exports/docs/ble5stack/ble_user_guide/html/ble-stack-5.x-guide/debugging-index-cc23xx.html#debugging-rf-output . This way you can confirm no radio operation occurs.

I hope this will help,

Best regards,

Please open a separate thread for this question.

Also, please be sure to clearly explain what you mean by "status" in such case.
