nRF52832 power consumption issue in system off mode

[mike_yang]

Hi,

I have power consumption issue about nRF52832 BLE application.

I found "Current consumption:Ultra-low power" informations in "nRF52832 Product Specification" as below

then I use "sd_power_sleep_off" enter system off mode after BLE stop advertisting.

But I cannot get uA current consumption.I have about 1mA current consumption,I don't know what's happened???

By the way, while I enter sleep mode before, I will disable TWI(nrf_drv_twi_disable) and release used GPIO(nrf_gpio_cfg_default).

My app is based on nRF5 SDK v16.0.0,s132 7.0.1 and use all BLE default configuartions.

Thanks!!

Hi

This sounds very much like your device is in debug mode. Emulated system OFF, which will run in debug mode, will not give the expected result in terms of power consumption. If you make sure that DEBUG is not set in your preprocessor definitions, and you power cycle your device, it should go out of debug mode.

Best regards,

Simon

Hi Simonr,

Could you tell me how to exit debug mode??

And how to check it??

Thanks!!
