vcoubard 542:1bf9c597f44f 37 * services/characteristics. isActive() can be used to determine status; and
vcoubard 542:1bf9c597f44f 38 * a termination callback (if setup) will be invoked at the end. Service

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

vcoubard 542:1bf9c597f44f 65 * filter (below) is set to the wildcard value, then a service
vcoubard 542:1bf9c597f44f 66 * callback will be invoked for the matching service (or for every

vcoubard 542:1bf9c597f44f 71 * to match against any characteristic. If both service-UUID
vcoubard 542:1bf9c597f44f 72 * filter and characteristic-UUID filter are used with non- wildcard
