Power consumption issue with custom nRF52832?

[vishal]

Hello sir,

I have develop product on nRF52832 DK and now i using custom nrf52832 board Here. I want to continuously on my device with BLE advertising continuously no sleep mode. for high speed BLE through put and continuously advertising we have set following parameter.

For my device power connection i use AA 1.5*2 = 3V battery cell. But sir now power consumption is very high how i can reduce power consumption for device for long battery life. How i calculate power consumption for continuously ON. I have turn off sleep mode in my programming.

But for saving power if i enable sleep mode in my application programming and then device go to sleep mode at that time how i can wake up device using android app without pressing any reset key. Is it possible please sir let know, and give me some tutorial link which is useful for reducing power consumption.

Thanks in Advanced....... Vishal

Hi,

What current consumption are you measuring? Are you measuring the high consumption both while advertising and in a connection?

For continuous advertising, you are using a very low advertising interval. In order to save power, you should increase this. You could increase it to at least 200 ms. I.e set APP_ADV_INTERVAL to 320. (in units of 0.625 ms. 320 corresponds to 200ms).

For the System OFF power mode, you need some external signal to wake it up(e.g. key press). You can not wake it up using a android app, since it's not possible to be in a BLE connection while in System OFF power mode.

You can find a good guide here. It's written for nRF51, but must of it also applies to the nRF52832.
