=== discoverServices() === | |||
; Description | |||
: The method discover services, characteristics, and descriptors offered by the remote GATT server. | |||
; Return | |||
: A Promise to indicate whether the operation is resolved or rejected. If the property [[B2G/Bluetooth/WebBluetooth-v2/BluetoothGatt#connectionState|connectionState]] is not <tt>connected</tt> when the method is called, the Promise would be rejected. | |||
; Sample | |||
var gatt = device.gatt; | |||
if (gatt && gatt.connectionState === "connected") { | |||
gatt.discoverServices().then ( function onResolve() { | |||
console.log("Services, characteristics, and descriptors are successfully discovered."); | |||
}, function onReject(aReason) { | |||
console.log("Rejected with this reason: ", aReason); | |||
}; | }; | ||
