![]() To check this, swipe up to get Control Center, and the AirPlay icon should be blue. Make sure AirPods is connected to Apple Watch.How to view AirPods battery percentage from your Apple Watch But one hidden feature when using AirPods with Apple Watch is being able to see AirPods battery life.įollow along to learn how to view this important piece of information…. One feature of Apple’s wireless AirPods earbuds is that they work really well with Apple products thanks to the W1 chip. With Series 3, Apple added support for LTE which allowed users to use Apple Watch without needing your iPhone nearby. When the connection is lost, you turn off the LED with the line: digitalWrite ( 13, LOW ) that takes pin 13 from 3.3V back to 0V, and turns the LED off.Apple Watch is increasingly becoming independent of the iPhone. In the main loop, you turn the LED on when the connection to the central device is detected with the line:Įvery 200ms the connection is tested and if still active, updateBatteryLevel is called. setLocalName ( "BatteryMonitorSketch1" ) setLocalName ( "BatteryMonitorSketch" ) īlePeripheral. ![]() If multiple boards will be running this sketch example in close proximity, you need to modify the local name so each can be uniquely identified.īlePeripheral. In the setup(), you initialize pin 13 as an output to drive the LED with pinMode ( 13, OUTPUT ) īlePeripheral is used to initialize the board as a Bluetooth® Low Energy peripheral with BLEPeripheral blePeripheral This sketch example partially implements the standard Bluetooth® Low-Energy Battery Service. This is read on the Bluetooth® Low Energy Control Panel on the smartphone under the "Battery Service" If it is changed, the code activates the printing on the Serial Monitor of the new value and updates the Battery characteristic with batteryLevelChar. The value is first checked against the former value read. It simulates the readiong of a battery with a potentiometer connected to A0. UpdateBatteryLevel() - This function is called every 200 millliseconds from the main loop. In this tutorial it is used to read the battery level of the device to which we connect as a peripheral. With Bluetooth® Low Energy it is possible to connect to and communicate with smartphones, tablets and peripherals that support this standard. Software Essentials LibrariesĬurieBLE.h is the library that gives access to all the parameters, features and functions of the Bluetooth® Low Energy module of the 101 board. A potentiometer is connected to 3.3V, GND and A0 to simulate the charge of a battery. The board has an embedded Bluetooth® Low Energy module, therefore it is enough to connect the board to the computer and use the Serial Monitor to read the messages sent by the sketch.
