https://devzone.nordicsemi.com/f/nordic-q-a/18269/read-battery-level-of-beacons---nrf-51822Hello, I have a low-level application that does bluetooth reading to find beacons, and I would like my application to read the battery level to display in my web application&#39;s platform. Would anyone have any links or concrete material to help? en-USTelligent Community 13Fri, 09 Dec 2016 08:30:11 GMThttps://devzone.nordicsemi.com/thread/70542?ContentTypeID=1Fri, 09 Dec 2016 08:30:11 GMT137ad170-7792-4731-bb38-c0d22fbe4515:95903020-edda-42e7-985c-8727eab7dd70J&#248;rgen Holmefjord<p>Hi,</p> <p>You can find some information about Measuring Lithium battery voltage with nRF51 in <a href="https://devzone.nordicsemi.com/blogs/30/measuring-lithium-battery-voltage-with-nrf51/">this blog post</a>. The <a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v12.2.0/ble_sdk_app_proximity.html?cp=4_0_0_4_2_2_15">proximity example</a> found in our SDK, measures the battery percentage and sends this over BLE using the <a href="https://www.bluetooth.com/specifications/gatt/viewer?attributeXmlFile=org.bluetooth.service.battery_service.xml">BAS profile</a>. There is also a battery measurement example available <a href="https://github.com/NordicSemiconductor/nrf51-ADC-examples/tree/master/ble_app_hrs_adc_battery_measurement">on our GitHub page</a>.
