Hi,

You can get both modified and removed. Try to send a text message the phone which is connected to the ANCS peripheral, then remove the text message notification on the phone. Below is the log output I got (SDK 15.3.0):

Notification // <-- new text message
<info> app: Event: Added
<info> app: Category ID: Social
<info> app: Category Cnt:1
<info> app: UID: 18
<info> app: Flags:
<info> app: Negative Action
<info> app:
Notification // Notification removed
<info> app: Event: Removed
<info> app: Category ID: Social
<info> app: Category Cnt:0
<info> app: UID: 18
<info> app: Flags:
<info> app: Negative Action

thank you Berg

I mean, when Event ID Notification Modified or Removed , can i get Notification Attributes( nrf_ble_ancs_c_app_attr_requestr )? 

i hope to get " App Identifier " ~

Hi,

I don't think it's possible to get attributes from a removed event. But you could keep track of the App identifier in your application, the UID seems to be unique: https://developer.apple.com/library/archive/documentation/CoreBluetooth/Reference/AppleNotificationCenterServiceSpecification/Specification/Specification.html#//apple_ref/doc/uid/TP40013460-CH1-SW10
