Generic BLE Service

[berkutta]

Hello,

I like to create a BLE Device with a nrf51822 which is able to receive 2 states from a BLE Phone. My idea is to set up a BLE Service within this BLE Device which is able to get received (with a writable service) a Byte which defines the 2 states.

Which BLE Service would you recommend for such a thing? I've had a look at http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.sdk5.v12.3.0%2Fgroup__ble__sdk__srv.html&cp=4_0_7_6_4 but haven't found anything as generic as I need it.

Thanks

Benjamin

Hi,

There is no such "generic" service in the SDK. You can use the Nordic UART Service to send strings indicating the states, as suggested by Toyman, or you can create you own custom service. See this tutorial.

Best regards,

Hi,

Thanks, the UART Service indeed looks perfect for my Application. I tried the ble_app_uart example and discovered compared to the ble_app_beacon a much higher current usage. Is there a special Flag I have to set to get the NRF into sleep mode between the advertisings when using the ble_app_uart example? I already tried to decrease the advertising interval to 1000ms.

Thanks
