Hello everyone.

Software:
X-CUBE-BLE1 (v. 2.5.2)
http://www2.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-expansion-software/x-cube-ble1.html
Example: Sensor Demo Application with DMA and low power mode (Project Name: DMA_LP_SDemo)

1) Equipment: NUCLEO-L053R8 + X-NUCLEO-IDB04A1
- Current consumption in operation mode advertising: about 15 µA
- Current consumption in operation mode connections: about 130 µA

2) Equipment: NUCLEO-L053R8 + X-NUCLEO-IDB05A1
- Current consumption in operation mode advertising: about 300 µA !!!
- Current consumption in operation mode connections: about 130 µA
Power supply voltage 3.3 V.

The problem lies in the very high consumption of X-NUCLEO-IDB05A1 mode advertising.
Has anyone encountered this problem?
