vcoubard 542:1bf9c597f44f 35 * active with callbacks being issued back into the application for matching
vcoubard 542:1bf9c597f44f 36 * services/characteristics. isActive() can be used to determine status; and
vcoubard 542:1bf9c597f44f 37 * a termination callback (if setup) will be invoked at the end. Service

vcoubard 542:1bf9c597f44f 43 * This is the application callback for matching service. Taken as

vcoubard 542:1bf9c597f44f 45 * when this callback is issued; calling asynchronous BLE-stack
vcoubard 542:1bf9c597f44f 46 * APIs from within this application callback might cause the
vcoubard 542:1bf9c597f44f 47 * stack to abort service discovery. If this becomes an issue, it
vcoubard 542:1bf9c597f44f 48 * may be better to make local copy of the discoveredService and
vcoubard 542:1bf9c597f44f 49 * wait for service discovery to terminate before operating on the
vcoubard 542:1bf9c597f44f 50 * service.

vcoubard 542:1bf9c597f44f 52 * This is the application callback for matching characteristic.

vcoubard 542:1bf9c597f44f 62 * interested. By default it is set as the wildcard UUID_UNKNOWN,
vcoubard 542:1bf9c597f44f 63 * in which case it matches all services. If characteristic-UUID
vcoubard 542:1bf9c597f44f 64 * filter (below) is set to the wildcard value, then a service
vcoubard 542:1bf9c597f44f 65 * callback will be invoked for the matching service (or for every
vcoubard 542:1bf9c597f44f 66 * service if the service filter is a wildcard).

vcoubard 542:1bf9c597f44f 69 * is interested. By default it is set as the wildcard UUID_UKNOWN
vcoubard 542:1bf9c597f44f 70 * to match against any characteristic. If both service-UUID
vcoubard 542:1bf9c597f44f 71 * filter and characteristic-UUID filter are used with non- wildcard
