peripherals power issue

[gootoomoon]

During ble ADV，my device will consume 60uA，when ADV stoped it will drop to 13uA. But when I get ble connected current will up to 130uA.

I test nrf51_sdk_v6_1_0_b2ec2e6\nrf51822\Board\nrf6310\s110\ble_app_hids_keyboard it‘s only 40-50uA when connected with phone.

I just use nrf51822 with no 32.768k crystal oscillator. no other component on my module.

Have close ADC, SPI , TWI, WDT and so on.

Hi

The current consumption mainly depends on the advertising interval and the connection interval of your application. Look at this thread, the "Tuning connection parameters" and "Tuning Advertising parameters" sections.

Do you use iphone in both cases? Are you using the S110 7.0.0 when you get the 60uA current consumption during advertising and 130uA during connection.

What is actually your advertising interval and connection interval in your application?
