S130 beacon app power profile

hakki goceoglu

Hi,

I am trying to modify the power profile table from S130 SDS to estimate the consumption of the beacon app. I know that stage (H) is 0, but what about stage (G) ? Is it also 0 ? Any other considerations ?

Cheers

Hakki

    The current is not 0 at stage H or G, see the RX current in the Product Specification part 8.5.2 and 8.5.3. You can also see the graph over the table showing approximate values. It will be hard to get a correct estimate because the time for the different stages will vary depending on payload size, response (connection request or scan response) and the post processing will vary with the type of advertising.

    The beacon app does non-connectable advertising which means that the radio turn-around stage and radio RX stage is not present. Here you can see measured current consumption for different scenarios. I also advise you to read this post on how to minimize current consumption.

    The measured current consumption on the ble_app_beacon example from SDK 11 on nRF51 DK is about 200uA. Increasing the interval (default is 100ms) or enabling DCDC will lower this.
