Since we change the service settings, but LightBlue still caches the old settings, it is
very likely that Apple device needs a complete power cycle to show the new
configuration. Press and hold POWER and HOME button of iOS devices for a few
seconds to perform a complete power down. Press POWER button to power it on
again. After power cycling and launch LightBlue app, the private service and
characteristics could be seen. Figure 7 shows the LightBlue that discovered private
services that we just defined.
