youkee 0:1ad0e04b1bc5 36 * active with callbacks being issued back into the application for matching
youkee 0:1ad0e04b1bc5 37 * services/characteristics. isActive() can be used to determine status; and
youkee 0:1ad0e04b1bc5 38 * a termination callback (if setup) will be invoked at the end. Service
youkee 0:1ad0e04b1bc5 39 * discovery can be terminated prematurely if needed using terminate().

youkee 0:1ad0e04b1bc5 43 * @param sc
youkee 0:1ad0e04b1bc5 44 * This is the application callback for matching service. Taken as
youkee 0:1ad0e04b1bc5 45 * NULL by default. Note: service discovery may still be active
youkee 0:1ad0e04b1bc5 46 * when this callback is issued; calling asynchronous BLE-stack
youkee 0:1ad0e04b1bc5 47 * APIs from within this application callback might cause the
youkee 0:1ad0e04b1bc5 48 * stack to abort service discovery. If this becomes an issue, it
youkee 0:1ad0e04b1bc5 49 * may be better to make local copy of the discoveredService and
youkee 0:1ad0e04b1bc5 50 * wait for service discovery to terminate before operating on the
youkee 0:1ad0e04b1bc5 51 * service.
youkee 0:1ad0e04b1bc5 52 * @param cc
youkee 0:1ad0e04b1bc5 53 * This is the application callback for matching characteristic.
youkee 0:1ad0e04b1bc5 54 * Taken as NULL by default. Note: service discovery may still be
youkee 0:1ad0e04b1bc5 55 * active when this callback is issued; calling asynchronous
youkee 0:1ad0e04b1bc5 56 * BLE-stack APIs from within this application callback might cause

youkee 0:1ad0e04b1bc5 58 * it may be better to make local copy of the discoveredCharacteristic
youkee 0:1ad0e04b1bc5 59 * and wait for service discovery to terminate before operating on the
youkee 0:1ad0e04b1bc5 60 * characteristic.
youkee 0:1ad0e04b1bc5 61 * @param matchingServiceUUID
youkee 0:1ad0e04b1bc5 62 * UUID based filter for specifying a service in which the application is
youkee 0:1ad0e04b1bc5 63 * interested. By default it is set as the wildcard UUID_UNKNOWN,
youkee 0:1ad0e04b1bc5 64 * in which case it matches all services. If characteristic-UUID
youkee 0:1ad0e04b1bc5 65 * filter (below) is set to the wildcard value, then a service
youkee 0:1ad0e04b1bc5 66 * callback will be invoked for the matching service (or for every
youkee 0:1ad0e04b1bc5 67 * service if the service filter is a wildcard).
youkee 0:1ad0e04b1bc5 68 * @param matchingCharacteristicUUIDIn
youkee 0:1ad0e04b1bc5 69 * UUID based filter for specifying characteristic in which the application
youkee 0:1ad0e04b1bc5 70 * is interested. By default it is set as the wildcard UUID_UKNOWN
youkee 0:1ad0e04b1bc5 71 * to match against any characteristic. If both service-UUID
youkee 0:1ad0e04b1bc5 72 * filter and characteristic-UUID filter are used with non- wildcard
youkee 0:1ad0e04b1bc5 73 * values, then only a single characteristic callback is
youkee 0:1ad0e04b1bc5 74 * invoked for the matching characteristic.
youkee 0:1ad0e04b1bc5 75 *
youkee 0:1ad0e04b1bc5 76 * @Note Using wildcard values for both service-UUID and characteristic-
youkee 0:1ad0e04b1bc5 77 * UUID will result in complete service discovery--callbacks being
youkee 0:1ad0e04b1bc5 78 * called for every service and characteristic.
