The selector shows all 8 modes as visual radio tiles. Tap a mode, confirm, and S2 automatically restarts into that mode.
USB Report Rate
| Option | Use Case |
|---|
| 125 Hz | Stability-oriented, legacy games |
| 250 Hz | Balanced |
| 500 Hz | Standard competitive |
| 1000 Hz | Lowest latency |
Higher report rates reduce input latency. Changing the rate causes S2 to restart automatically.
Mute Mode
Controls how the mute hotkey behaves:
| Mode | Behavior |
|---|
| Hold | Mute active while the hotkey is held down |
| Toggle | Press once to mute, press again to unmute |
Office Mode
When enabled, S2 outputs as a standard keyboard and mouse rather than a controller — useful for desktop tasks.
| Setting | Range / Default | Notes |
|---|
| Enable/Disable | OFF | Toggle |
| Mouse Sensitivity | 0.01–1.00 | Desktop tasks need lower sensitivity than gaming |
| Output Port | C1 / C2 | Which USB-C port to send output |
| Auto Start | ON / OFF | Launch office mode on power-up |
| Activation Hotkey | Configurable | Key combo to enter office mode |
Custom Bluetooth Name
Set a friendly name (up to 15 UTF-8 bytes) for S2’s BLE broadcast. Helps identify your device when multiple S2 units are nearby.
IO Monitor
The IO Monitor is a real-time input viewer — a unique S2 feature not found on competing converters.
| Section | What It Shows |
|---|
| Port Status | USB1–4, Bluetooth — each port’s connected device name and input state |
| Key Presses | Up to 12 simultaneous keys with their mapped labels |
| Analog Values | Real-time X/Y stick values for both thumbsticks |
| System Info Panel | Currently loaded macro, active macro, system state, connected peripheral names |
💡 Tip: The IO Monitor is your best debugging tool. If a button isn’t working in-game, open this page and press it — you will immediately see whether S2 detects the input and what it maps to.
Hotkey Selector
Every action that can be bound to a key (config switching, macro activation, mute, office mode) uses the Hotkey Selector to assign the trigger.
| Input Method | Description |
|---|
| Keyboard | Browse a visual grid of all keyboard keys with icons |
| Mouse | Left/Right/Middle/Side/Scroll Wheel/Mouse movements |
| Combo Keys | pre-defined combination keys |
| Search | Press the physical buttons on devices plugged into S2 — APP captures the key code in real time |
⚙️ Advanced — Search: Instead of picking from a grid, you press the actual key you want to use, and S2 learns it instantly. This is the fastest way to set a hotkey, especially for unusual keyboards.
4 - Bluetooth Pairing
How to pair your phone with ReaSnow S2 over BLE — first-time pairing, auto-reconnect, custom Bluetooth name, and troubleshooting.
S2 communicates with the ReaSnow Manager APP exclusively over Bluetooth Low Energy (BLE). There is no USB data connection between the APP and S2 — all configuration, firmware updates, and real-time monitoring happen wirelessly.
First-Time Pairing
- Power on S2 — the LED will show slow-flashing blue (waiting for BLE connection).
- On your phone, turn on Bluetooth and Location/GPS.
- Open the ReaSnow Manager APP.
- The APP automatically scans for nearby S2 devices — look for a device name starting with ReaSnow-S2- followed by a unique identifier.
- Tap your S2 in the device list to connect.
- The LED changes to solid blue when connected.
ℹ️ Info: Grant Bluetooth and Location permissions when asked. On Android, BLE scanning requires Location permission at the OS level — this is an Android requirement, not an S2 requirement.
Auto-Reconnect
S2 remembers the last paired phone. After the initial pairing:
- Power on S2 → the APP auto-reconnects within 5 seconds (if the APP is open and Bluetooth is on).
- If the BLE connection drops unexpectedly, the APP automatically attempts to reconnect.
- Upon reconnect, the APP resets to the Home tab.
Connection Rules
| Rule | Detail |
|---|
| One phone at a time | S2 accepts only one BLE connection. A second phone cannot connect while another is paired. |
| Range | Up to 10 meters in open air. For firmware updates, stay within 2 meters. |
| No USB tethering | APP-to-S2 communication is BLE only. The USB ports carry no data connection to the phone. |
Custom Bluetooth Name
Set a custom name for your S2’s BLE broadcast to make it easy to identify when multiple units are nearby:
- Go to Settings → Global Settings → Custom Bluetooth Name.
- Enter a name up to 15 bytes (UTF-8).
- Tap Save — the new name takes effect immediately.
Useful in tournament or LAN party settings where several players may have S2 devices in range.
Troubleshooting
| Symptom | Likely Cause | Solution |
|---|
| S2 not showing in device list | Bluetooth or Location is off | Turn on both Bluetooth and Location; grant permissions to the APP |
| S2 not showing in device list | S2 is already connected to another phone | Disconnect the other phone or power-cycle S2 |
| Connection drops frequently | Too far from S2 or BLE interference | Move closer; avoid dense wireless environments (Wi-Fi routers, other Bluetooth devices) |
| Connection drops during firmware update | Phone screen turned off or APP backgrounded | See Firmware Update for update rules |
| LED stays slow-flashing blue | Paired phone not in range or APP not open | Open the APP; check that Bluetooth is enabled |
💡 Tip: If nothing else works, restart your phone’s Bluetooth, power-cycle S2, and try again. This resolves most BLE pairing issues.
5 - Firmware Update
OTA firmware upgrade over BLE, version channels, and recovery on ReaSnow S2.
S2 firmware is updated wirelessly through the ReaSnow Manager APP — no PC, no USB cable, no file downloads required.
Update Channels
Choose a channel based on your needs:
| Channel | Description |
|---|
| Stable | Production-ready firmware. Recommended for all users. |
| Beta | Pre-release builds with new features. Minor issues possible. |
| Alpha | Development builds. For testing only — expect bugs. |
💡 Tip: Stay on the Stable channel unless you are testing a specific fix or feature with guidance from ReaSnow support.
How to Update
- Open the ReaSnow Manager APP and connect to S2.
- Navigate to Settings → Firmware Upgrade.
- The APP checks the server for available updates.
- If a newer version is available, tap Upgrade.
- The upgrade proceeds in four phases:
| Phase | Description |
|---|
| Version Check | APP compares local firmware version against the server manifest |
| Erase | S2 erases its old firmware partition |
| Download & Write | Firmware is sent over BLE. |
| Result Query | APP confirms the upgrade completed successfully |
During the Update
| What You See | What It Means |
|---|
| Progress percentage | Overall completion |
| Speed (KB/s) | Current BLE transfer rate |
| Estimated time remaining | Countdown to completion |
Important Notes
⚠️ Warning — follow these or the upgrade may fail:
| Rule | Reason |
|---|
| Keep the APP in the foreground | Backgrounded apps may be suspended by the OS |
| Do not let the phone screen turn off | Screen-off can interrupt the BLE connection |
| Disable battery saver / power-saving mode | Power saving throttles BLE throughput |
| Stay within 2 meters of S2 | BLE signal weakens with distance |
| Do not unplug S2 | Power loss during flashing can corrupt firmware |
Recovery
If an upgrade fails:
- The APP shows an error message with the failed phase.
- S2 remains in its current working state — a failed upgrade does not brick the device.
- Tap Retry to attempt the upgrade again.
- If repeated attempts fail, try:
- Moving closer to S2 (within 1 meter).
- Restarting the APP.
- Power-cycling S2.
- Switching to a different phone if BLE performance is consistently poor.
If the issue persists, contact ReaSnow support with your current firmware version and the error message.
