# Notifications
## Overview
MeshCore Open provides both **system notifications** (push-style OS alerts) and **in-app unread badges** to inform users of new activity.
## Notification Types
### 1. Direct Message Notifications
- **Triggered when**: A new incoming message arrives from a Chat or Room contact
- **Title**: Contact's name
- **Body**: Message text (reactions show "Reacted [emoji]", GIFs show "Sent a GIF")
- **Priority**: High
- **Android channel**: `messages`
### 2. Channel Message Notifications
- **Triggered when**: A new message arrives on a non-muted channel
- **Title**: Channel name (or "Channel N" if unnamed)
- **Body**: `"<senderName>: <message text>"`
- **Priority**: High
- **Android channel**: `channel_messages`
### 3. Advertisement Notifications
- **Triggered when**: A new node is discovered on the mesh for the first time
- **Title**: "New [type] discovered" (e.g., "New chat node discovered")
- **Body**: Contact's name
- **Priority**: Default
- **Android channel**: `adverts`
### 4. Background Service Notification (Android Only)
- A persistent low-priority notification: "MeshCore running — Keeping BLE connected"
- Required by Android for foreground services to keep BLE alive in the background
- Tap to re-launch the app
- **Does not auto-start on reboot** — the user must re-open the app manually after a phone restart
### Notification Tap Behavior
Tapping a notification currently re-launches the app at the root route. It does **not** navigate directly to the relevant chat or channel.
## In-App Unread Badges
Red numeric badges appear throughout the UI:
- **Contacts list**: Each contact row shows a red pill badge (e.g., "3") for unread messages
- **Channels list**: Each channel row shows an unread badge
- **Chat screen subtitle**: Shows unread count inline
- Badges cap at "99+" for display
### How Unread Counts Work
- Stored per contact (by public key) and per channel, **scoped to the connected device's identity** (first 10 hex characters of its public key). Switching between different radios gives each its own independent unread state
- **Suppressed when viewing**: Opening a chat resets the count to 0 and cancels the OS notification
- **Ignored for**: Outgoing messages, CLI messages, and repeater contacts
- Debounced writes (500ms) to avoid excessive storage I/O during message bursts
## Notification Settings
Access via **App Settings → Notifications**:
| Setting | Default | Description |
|---|---|---|
| Enable Notifications | On | Master toggle; requests OS permission when turned on |
| Message Notifications | On | DM alerts (greyed out if master is off) |
| Channel Message Notifications | On | Channel alerts (greyed out if master is off) |
| Advertisement Notifications | On | New node alerts (greyed out if master is off) |
### Per-Channel Muting
Long-press a channel in the channels list → "Mute channel" / "Unmute channel". Muted channels do not generate OS notifications.
There is no per-contact muting.
## Rate Limiting
The notification system prevents notification storms:
- **Minimum interval**: 3 seconds between individual notifications
- **Batch window**: If multiple notifications arrive within 5 seconds, they are combined into a single summary notification on a fourth Android channel (`batch_summary`): "MeshCore Activity — 2 messages, 1 channel message, 3 new nodes". Note: batch summaries are Android-only; on Apple platforms individual notifications are shown
## Notification Clearing
- **Opening a contact chat**: Cancels the OS notification and resets unread count
- **Opening a channel**: Cancels the channel notification and resets unread count
- **Opening Contacts screen**: Cancels all advertisement notifications
