Bluetooth current Consumption

Hi,

I am using the STM32WB5MMG MCU, and I would like to know the current consumption of CPU1 and CPU2 while Bluetooth is in General Discovery mode (scanning) and Advertising.

Additionally, are there any methods to reduce the current consumption of CPU2? For example, would reducing the TX power level during advertising or scanning help decrease power consumption?

Thanks,
Sainath D

Hello @SDhar.1 

To reduce the current consumption of your system will using BLE, I suggest you reduce the TX Power, improve the connection and advertising intervals and try to use the Low power modes for the maximum time. For the Current consumption measurement on advertising and connection, I suggest you measure it using you own design and FW since it depends on your project SW and HW configurations.

Best Regards.
