Battery life when use GATT server/client

[Javier]

Hi!,

I'm working in a Android app to communicate with a nRF52/nRF51 boards.

I've been using Bluetooth Smart nRF51822 Beacon Kit.

But I think what I need is not possible with Beacon's (iBeacons or Eddystone), I'm not sure.

I need to hear from the PCA20006 frames and when the Android app receive one whose UUID match the established in the smartphone Android App can request more data, such as Timestamp.

I'm thinking to use the BLE GATT with Softdevice S130 to nRF51 and/or Softdevice S132 to nRF52.

BLE Gatt server to PCA20006 when in advertising mode and Android Smartphone at Gatt Client. And vice versa when Smartphone received the response and send some data to the PCA2006.

Also I need to use AES-CCM cryptography.

But I have one doubt, about the battery life.

A CR2477 battery could last 2 years if done between 500-1,000 daily transactions? (using GATT)

Best regards

I found an interesting post about this:

and this excel file to calculate the power consumption: devzone.nordicsemi.com/.../abd9550ebc46e6bbd0678d9b9a70ca90

For nRF52832 there is an online power calculator here.
