BlueNRG-MS (X-NUCLEO-IDB05A1) too much power consumption

Posted on March 16, 2016 at 09:38

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 �A

- Current consumption in operation mode connections: about 130 �A

2) Equipment: NUCLEO-L053R8 + X-NUCLEO-IDB05A1

- Current consumption in operation mode advertising: about 300 �A !!!

- Current consumption in operation mode connections: about 130 �A

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?
