characteristic notify enable question

[sam]

Hi,

I'm developing a BLE device which has one custom service and three characteristic, each characteristic has read/notify
properties.  My proglem is, when my device connects to the phone through  "Setting" -> "Bluetooth",
the strange thing is only first characteristic's notify is enabled while the other two are not.  I'm wondering if I have
to enable the notification through Android(or iPhone) App, not by "Setting" -> "Bluetooth"? If so, then why there's one
characteristic's notify is enabled when connected?  Anyone can help? 

Many Thanks...

Hi,

Like you mentioned, you have to enable the notification through a custom app on Android/iOS. You can't enable notification from the phone setting. Not sure why only one characteristic's notify is enabled.
