radio notifications and sd_flash_*()

[rgrr2]

Hi,

I have an application where both radio notifications and flash operations are used.

It seems that every sd_flash_write() generates two radio notifications. So during startup of my application there is a burst of radio notifications although there is actually no radio operation. Even advertising is still off.

Is my observation correct? And how can this be prevented from happening?

Thanks, Hardy

Hi Hardy,

The best way to perform power consumption measurements is with the Power Profiler Kit (PPK). It will give you a very detailed look at the performance of your application.

I have forwarded your suggestion to add the relevant information to the radio notification documentation.

Hi Ketil, the PPK is not a solution, because our device has an available current budget. Actual current has to be calculated according to connection parameters and actual data throughput. Because connection parameters vary from device to device, offline calculation/measurement would not be enough. Calculation / measurement has to happen in target.
