RTOS/LAUNCHXL-CC2640R2: Possible to turn off Bluetooth functions such as advertising in multi_role or SimpleBLEPeripheral?

Other Parts Discussed in Thread: BLE-STACK

Tool/software: TI-RTOS

I'm trying to save as much power as possible when power_sleep()-ing my device to standby mode. With multi_role and SBP, the device is waking up periodically from standby mode to scan for Bluetooth connections. I want it to stay in standby mode, and not wake up.

Maybe if I disable part of the or even the entire Bluetooth protocol, then it will stay in standby. Then when it powers back on, I can restore the Bluetooth.

Is this possible? If so, how? Thank you in advance.

Maybe you can make CC2640R2 into shutdown mode.

Thanks for answering. Is there a way to keep it in Standby mode? I need to preserve the memory.

Hi Rich,
Power saving is handled by RTOS. If you disable periodic events or remove whatever BLE API calls you use to trigger Scanning or Advertisement, the device will go into Standby. I believe you will find this SLA useful

Thanks for the link. Just to clarify, all the standby mode prerequisites (stated in 6.6.4 of SWCU117H Technical Reference) such as powering down AUX_PD is done automatically by RTOS/BLE-stack?
