Software for the Svive Flow 7
The Svive Flow 7 is a light wireless gaming mouse with a 2.4 GHz receiver. When this project started, we could not find any official software for it, so there was no way to see the battery level or change DPI, polling rate or sleep settings from Windows. CompxTray fills that gap. It talks to the mouse through its receiver, shows the battery level in the tray, and lets you change the same settings that gaming mouse software from other brands offers.
Features
- Battery in the tray. The tray icon shows the battery percentage and changes colour as the battery drains. It also shows when the mouse is charging or asleep.
- Low battery warnings at 20 % and 10 %, and a note when the mouse is fully charged.
- Polling rate 125 / 250 / 500 / 1000 Hz, with a built-in tool that measures the rate the mouse actually reports at.
- DPI stages. Set how many stages the mouse has (1 to 6) and the DPI of each, from 100 to 30 000 in steps of 50.
- Sensor: lift-off distance, motion sync and button debounce.
- Sleep timer from 30 seconds to 30 minutes.
- Safe writes. CompxTray reads every change back from the mouse to verify it. It also saves a backup of the original settings the first time it reads a mouse, and you can restore them with one click.
- Lightweight. A single small
.exe with no installer, no account and no network access. It runs on the .NET Framework that comes with Windows 10 and 11.
Supported devices
| Mouse | Receiver ID | Battery | Settings |
|---|
| Svive Flow 7 | 373B:11B3 | ✅ | ✅ verified |
| Svive Flow 5, Flow S5, Flow S7 | not tested | probably ✅ | read-only until verified |
Other Compx mice (373B:*, 3554:*) | | likely ✅ | read-only until verified |
Do you have another Svive mouse? Run CompxTray and see if the battery shows up, then help verify it. Many mice from VXE, ATK, Attack Shark and other brands also use Compx chips. Battery reading uses the same command across the family, so it will probably work on them too. Settings are only writable on verified models, because some Compx firmwares lay out their memory differently. See Adding a mouse.
What has been tested on the Flow 7
All of this was checked on real hardware with the guided test in tools\verify-writes.bat:
| Setting | Written and read back | Effect confirmed |
|---|
| Polling rate | ✅ | ✅ measured 500 and 1000 Hz |
| DPI values | ✅ | ✅ pointer speed changes immediately |
| Number of DPI stages | ✅ | ✅ the DPI button cycles through an added stage |
| Active stage display | ✅ | ✅ follows the DPI button live |
| Lift-off (Low / High) | ✅ | ✅ Low stops tracking closer to the surface |
| Debounce | ✅ | ✅ clicks behave normally at 2 ms |
| Motion sync | ✅ | not visible to the eye |
| Sleep timer | ✅ | ✅ |
| Settings after power off | ✅ | ✅ all kept |
| Restore original settings | ✅ | ✅ |
På svenska: programvara för Svive-mus
CompxTray är en gratis, inofficiell programvara för Svive Flow 7. Med den ser du batterinivån på din Svive-mus direkt i aktivitetsfältet och kan ändra musens inställningar i Windows, något som annars saknas för den här musen.
Det här kan du göra:
- Batterinivå: procent i aktivitetsfältet, med varning när batteriet börjar ta slut och besked när musen är fulladdad.
- DPI: antal DPI-steg (1 till 6) och DPI för varje steg, från 100 till 30 000.
- Polling rate: 125, 250, 500 eller 1000 Hz, med en inbyggd mätning av vad musen faktiskt skickar.
- Övriga inställningar: lift-off distance, debounce, motion sync och viloläge (30 sekunder till 30 minuter).
- Säkerhet: allt läses tillbaka från musen efter varje ändring, och originalinställningarna sparas så att du kan återställa dem.
Så kommer du igång: ladda ner CompxTray.exe under Releases och starta den. Dubbelklicka på batteriikonen nere vid klockan för att öppna inställningarna. Appen är på engelska.
Vanliga frågor
Finns det någon programvara till Svive Flow 7?
Vi hittade ingen officiell programvara eller drivrutin för inställningar när projektet startade. Musen fungerar utan drivrutin i Windows, men för att se batteriet eller ändra DPI och polling rate behöver du ett program som CompxTray.
Hur ser jag batterinivån på min Svive-mus?
Starta CompxTray. Batteriet visas i procent i aktivitetsfältet och uppdateras automatiskt.
Kan jag ändra DPI och polling rate på Svive Flow 7?
Ja. Öppna CompxTray, välj fliken Performance för polling rate och DPI för DPI-stegen, och klicka Apply.
Fungerar det med Svive Flow 5, Flow S5 eller Flow S7?
Troligen för batteriet, eftersom de verkar bygga på samma typ av chip, men det är inte testat. Inställningarna går bara att läsa tills modellen är verifierad. Har du en sådan mus får du gärna hjälpa till att testa.
Är CompxTray från Svive?
Nej. Det är ett fristående hobbyprojekt med öppen källkod och har ingen koppling till Svive.
FAQ
Is there official software for the Svive Flow 7?
When this project started, we could not find any official software or settings driver for the Flow 7. The mouse works in Windows without a driver, but to see the battery level or change DPI and polling rate you need a tool like CompxTray.
How do I check the battery level of my Svive mouse?
Run CompxTray. The battery percentage is shown in the tray and updates automatically.
Can I change the DPI and polling rate of the Svive Flow 7?
Yes. Open CompxTray, use the Performance tab for the polling rate and the DPI tab for the DPI stages, then click Apply.
Does it work with the Svive Flow 5, Flow S5 or Flow S7?
Probably for the battery level, since they appear to use the same kind of chip, but they have not been tested. Settings stay read-only until a model is verified. If you own one, please help verify it.
Is CompxTray made by Svive?
No. It is an independent open-source project with no connection to Svive.
Install
- Download
CompxTray.exe from Releases.
- Run it. The battery icon appears in the tray.
- Double-click the tray icon to open the settings. To start CompxTray automatically, use App → Start with Windows.
About the SmartScreen warning
The first time you run it, Windows may show "Windows protected your PC". The exe is not code-signed yet, and SmartScreen warns about new, unknown programs until enough people have run them. To check the file before you run it:
- GitHub builds it, not a person. Every release exe is built by GitHub Actions from the source in this repository. You can read the build log for each release.
- Compare the checksum. The SHA-256 checksum is published next to the exe in the release. Compare it with
Get-FileHash CompxTray.exe in PowerShell.
- Or build it yourself. Run
build.bat (below). A file you build yourself never triggers SmartScreen.
To run a downloaded release: More info → Run anyway. Code signing through SignPath Foundation is planned once the project qualifies.
Settings, the log and backups are stored in %APPDATA%\CompxTray.
Build from source
You don't need Visual Studio or an SDK. The C# compiler that ships with Windows (.NET Framework 4.x) is enough.
git clone <this repository>
cd CompxTray
build.bat
build.bat compiles bin\CompxTray.exe and starts it. build.bat --ci only builds; GitHub Actions uses it to build every push and to attach the exe to tagged releases.
Other command-line options:
| Option | What it does |
|---|
--open | Start in the tray and open the window |
--demo | Open the window with sample data, no mouse needed and nothing is written |
--screenshot <dir> [--demo] | Save one PNG per tab (used for the images above) |
How it works
The USB receiver exposes a vendor-specific HID interface (usage page 0xFF02) with 17-byte reports. CompxTray sends small commands on it: read battery, read memory and write memory. It then reads and writes the mouse's settings memory directly, with the same checksummed values the mouse already stores. The full details are in docs/PROTOCOL.md.
Adding a mouse
If you have another Compx-based mouse, you can help verify it. The first two tools only read.
- Run
tools\probe.ps1, which lists your HID devices.
- Run
tools\read-settings.ps1, which dumps and decodes the settings memory. Check that the decoded DPI stages and polling rate match what the mouse is set to.
- Only if step 2 matches, run
tools\verify-writes.bat. It changes each setting, asks what you notice, and restores everything at the end.
- Open an issue with the reports.
powershell -NoProfile -ExecutionPolicy Bypass -File tools\read-settings.ps1
If the memory matches the known layout, the model can be added to the verified list in src/Device/ConfigMap.cs.

The protocol was pieced together from public reverse-engineering work by others. Thank you:
CompxTray's code is written from scratch; only protocol facts were taken from these projects. The memory map was confirmed by reading a real Svive Flow 7.
