The enumerated values for this field are defined in EventID Values. * EventFlags: A bitmask whose set bits inform an NC of specificities with the iOS notification. For example, if an iOS notification is considered “important”, the NC may want to display a more aggressive user interface (UI) to make sure the user is properly alerted. The enumerated bits for this field are defined in EventFlags. * CategoryID: A numerical value providing a category in which the iOS notification can be classified. The NP will make a best effort to provide an accurate category for each iOS notification. The enumerated values for this field are defined in CategoryID Values. * CategoryCount: The current number of active iOS notifications in the given category. For example, if two unread emails are sitting in a user’s email inbox, and a new email is pushed to the user’s iOS device, the value of CategoryCount is 3. * NotificationUID: A 32-bit numerical value that is the unique identifier (UID) for the iOS notification. This value can be used as a handle in commands sent to the Control Point characteristic to interact with the iOS notification. */ char *EventID_to_String(uint8_t EventID) { char *str = NULL; switch (EventID) { case EventIDNotificationAdded: str = "New message"; break; case EventIDNotificationModified: str = "Modified message"; break; case EventIDNotificationRemoved: str = "Removed message"; break; default: str = "unknown EventID"; break; } return str; } char *CategoryID_to_String(uint8_t CategoryID) { char *Cidstr = NULL; switch(CategoryID) { case CategoryIDOther: Cidstr = "Other"; break; case CategoryIDIncomingCall: Cidstr = "IncomingCall"; break; case CategoryIDMissedCall: Cidstr = "MissedCall"; break; case CategoryIDVoicemail: Cidstr = "Voicemail"; break; case CategoryIDSocial: Cidstr = "Social"; break; case CategoryIDSchedule: Cidstr = "Schedule"; break; case CategoryIDEmail: Cidstr = "Email"; break; case CategoryIDNews: Cidstr = "News"; break; case CategoryIDHealthAndFitness: Cidstr = "HealthAndFitness"; break; case CategoryIDBusinessAndFinance: Cidstr = "BusinessAndFinance"; break; case CategoryIDLocation: Cidstr = "Location"; break; case CategoryIDEntertainment: Cidstr = "Entertainment"; break; default: Cidstr = "Unknown CategoryID"; break; } return Cidstr; } /* | EventID(1 Byte) | EventFlags(1 Byte) | CategoryID(1 Byte) | CategoryCount(1 Byte) | NotificationUID(4 Bytes) | */ void ble_receive_apple_notification_source(uint8_t *message, uint16_t message_len) { if (!message || message_len < 5) { return; } uint8_t EventID = message[0]; char *EventIDS = EventID_to_String(EventID); uint8_t EventFlags = message[1]; uint8_t CategoryID = message[2]; char *Cidstr = CategoryID_to_String(CategoryID); if (EventID == EventIDNotificationAdded){ led_set_by_category(CategoryID); } uint8_t CategoryCount = message[3]; uint32_t NotificationUID = (message[4]) | (message[5]<< 8) | (message[6]<< 16) | (message[7] << 24); ESP_LOGI(NimBLE_ANCS_TAG, "EventID:%s EventFlags:0x%x CategoryID:%s CategoryCount:%d NotificationUID:%" PRIu32, EventIDS, EventFlags, Cidstr, CategoryCount, NotificationUID); } void ble_receive_apple_data_source(uint8_t *message, uint16_t message_len) { if (!message || message_len == 0) { return; } uint8_t Command_id = message[0]; switch (Command_id) { case CommandIDGetNotificationAttributes: { uint32_t NotificationUID = (message[1]) | (message[2]<< 8) | (message[3]<< 16) | (message[4] << 24); uint32_t remian_attr_len = message_len - 5; uint8_t *attrs = &message[5]; ESP_LOGI(NimBLE_ANCS_TAG, "recevice Notification Attributes response Command_id %d NotificationUID %" PRIu32, Command_id, NotificationUID); while(remian_attr_len > 0) { uint8_t AttributeID = attrs[0]; uint16_t len = attrs[1] | (attrs[2] << 8); if(len > (remian_attr_len -3)) { ESP_LOGE(NimBLE_ANCS_TAG, "data error"); break; } switch (AttributeID) { case NotificationAttributeIDAppIdentifier: ESP_LOG_BUFFER_CHAR("Identifier", &attrs[3], len); break; case NotificationAttributeIDTitle: ESP_LOG_BUFFER_CHAR("Title", &attrs[3], len); break; case NotificationAttributeIDSubtitle: ESP_LOG_BUFFER_CHAR("Subtitle", &attrs[3], len); break; case NotificationAttributeIDMessage: ESP_LOG_BUFFER_CHAR("Message", &attrs[3], len); break; case NotificationAttributeIDMessageSize: ESP_LOG_BUFFER_CHAR("MessageSize", &attrs[3], len); break; case NotificationAttributeIDDate: //yyyyMMdd'T'HHmmSS ESP_LOG_BUFFER_CHAR("Date", &attrs[3], len); break; case NotificationAttributeIDPositiveActionLabel: ESP_LOG_BUFFER_HEX("PActionLabel", &attrs[3], len); break; case NotificationAttributeIDNegativeActionLabel: ESP_LOG_BUFFER_HEX("NActionLabel", &attrs[3], len); break; default: ESP_LOG_BUFFER_HEX("unknownAttributeID", &attrs[3], len); break; } attrs += (1 + 2 + len); remian_attr_len -= (1 + 2 + len); } break; } case CommandIDGetAppAttributes: ESP_LOGI(NimBLE_ANCS_TAG, "recevice APP Attributes response"); break; case CommandIDPerformNotificationAction: ESP_LOGI(NimBLE_ANCS_TAG, "recevice Perform Notification Action"); break; default: ESP_LOGI(NimBLE_ANCS_TAG, "unknown Command ID"); break; } } char *Errcode_to_String(uint16_t status) { char *Errstr = NULL; switch (status) { case Unknown_command: Errstr = "Unknown_command"; break; case Invalid_command: Errstr = "Invalid_command"; break; case Invalid_parameter: Errstr = "Invalid_parameter"; break; case Action_failed: Errstr = "Action_failed"; break; default: Errstr = "unknown_failed"; break; } return Errstr; }
