Consuming higher current @ 1 ms advertising interval as expected according to online BLE power profiler.

[[email protected]]

Hi,

I'm using nRF52805. I need to advertise BLE continuously according my application but also have to reduce power consumption because device is battery operated.

Currently advertising interval is 1 ms and it's consuming around 4mA with 3.3V supply which is too much high for my application.

Kindly, suggest how I can reduce the power consumption,what will be the advertising interval and all related setting need to do for less power consumption.

Thanks

Are you just using the nRF?

I stumbled across the problem that depending on the periphery you'll need to explicitely activate the pull-ups/pull-downs to avoid leaky current on "disconnected" GPIOs.

I'm using nrf5 sdk and disconnected GPIOs already taken care so this case is covered.

Are you sure you meant to write 1ms advertising interval? If so, what is your expected current consumption? Can you share a screenshot of the online power profiler window? Because I am not able to set the advertising interval that low. Other than that, make sure to turn off logging (particularly if you are using the UART backend).

Other than that it is difficult to say what you need to do. Are you using the nRF5 SDK or NCS?

Best regards,

I'm sorry, Actually, it was 10 ms advertising interval, it was a typo mistake, Now, I configured it for 40 ms and it consuming almost around 4 mA, which is too high for my application, I need to restrict current consumption between 200 - 250 uA. I am sharing screenshot of BLE profile configuration according to my existing application settings, it shows around 200 uA current, which will be fine for my application, if i achieve the same. Please, how to achieve required current consumption.

This depends on what else that you have going in your application. Did you disable the logging in your project? Do you use any other peripherals in your application than the radio (through the softdevice)?
