When your WalkingPad app is not connecting via Bluetooth, the most frustrating part is that everything looks fine — Bluetooth is on, the pad is powered, the app is open — and still nothing happens. KS Fit (WalkingPad’s official app, by KingSmith) can be finicky about pairing, and the causes range from a stale Bluetooth cache on your phone to another device secretly holding the pad’s one and only connection slot.
This guide explains how KS Fit pairing actually works, then walks you through a step-by-step fix in the order that solves the most cases. If your pad won’t start at all (with or without the app), start with our beeping-but-not-starting guide instead.
Quick Answer: WalkingPad App Not Connecting via Bluetooth in 30 Seconds
| Question | Answer |
|---|---|
| Why won’t KS Fit find my WalkingPad? | The most common causes: the pad is already connected to another phone/app, your phone’s Bluetooth cache is stale, or the app lacks location/Bluetooth permissions. |
| Should I pair from my phone’s Bluetooth settings? | No — pair from inside the KS Fit app, not from iOS/Android Bluetooth settings. Pairing at the OS level first is a leading cause of connection failures. |
| Can two phones connect to one WalkingPad? | No. Only one Bluetooth client can connect to a walking pad at a time. Disconnect every other phone, tablet, and app first. |
| Does the pad need to be on to pair? | Yes — the pad must be powered on, unfolded flat, and within a few meters of your phone. |
How KS Fit Pairing Actually Works (and Why It Breaks)
Understanding the mechanism makes the fixes obvious. Here’s what’s happening behind the scenes:
- The pad advertises itself over Bluetooth Low Energy (BLE). When powered on, your WalkingPad broadcasts its presence. KS Fit scans for these broadcasts and filters by known WalkingPad device names — this is why the pad must be powered on before you open the app’s scan.
- Only one BLE client at a time. This is the big one, confirmed by WalkingPad BLE protocol research: a walking pad accepts exactly one Bluetooth connection. If your partner’s phone, an old tablet, a fitness app, or even a previous session of KS Fit on your own phone still holds that slot, no new connection can succeed. The pad will simply be invisible or refuse the new link.
- Pairing is unauthenticated. There is no PIN and no bonding step — the app just connects. That means if the connection drops, the fix is never “enter a code”; it’s always about clearing whatever is blocking the fresh connection.
- The OS Bluetooth menu is not the way in. Pairing the pad in your phone’s system Bluetooth settings can actually prevent KS Fit from connecting, because the OS-level pairing can hold or confuse the connection state the app needs. Always initiate pairing from inside the app.
With that model in mind, nearly every “app not connecting” case is one of: something else holds the connection slot, the phone’s Bluetooth stack has stale data, the app can’t scan (permissions), or the app/pad software is out of date.
How to Fix KS Fit Bluetooth Pairing: Step by Step
Follow these in order — each step eliminates one common cause.
- Free the pad’s single connection slot. This fixes the majority of cases. On every phone and tablet in the household, either turn Bluetooth off entirely or open Bluetooth settings and “Forget” the WalkingPad entry. Also force-close KS Fit and any other fitness apps that might connect to the pad. Only one device should have Bluetooth on: the phone you’re pairing with.
- Power-cycle the pad. Turn the pad off, unplug it for 30 seconds, plug it back in, unfold it completely flat, and power it on. A fresh power-up makes the pad broadcast cleanly. Keep your phone within 2–3 meters during pairing.
- Restart your phone’s Bluetooth. Toggle Bluetooth off, wait 10 seconds, and toggle it back on. This clears transient stack glitches without wiping your other pairings.
- Check app permissions. KS Fit needs Bluetooth and location permissions to scan for BLE devices (on Android, BLE scanning is gated behind location permission — this is an OS requirement, not the app being nosy). Go to your phone’s app settings → KS Fit → Permissions, and grant Bluetooth, Location (set to “While using the app” or “Always”), and any nearby-devices permission your OS version shows.
- Pair from inside the app. Open KS Fit, go to the device-adding/pairing screen, and start the scan there. Do NOT go to your phone’s Settings → Bluetooth and tap the pad’s name. If you previously paired it at the OS level, forget that entry first (step 1), then pair via the app.
- Update the app. Check the App Store or Google Play for a KS Fit update. WalkingPad’s own manual lists “app not updated” as a documented cause of connectivity issues. Update, force-close, and reopen.
- Clear the app’s Bluetooth cache (Android). Go to Settings → Apps → KS Fit → Storage → Clear Cache. If that doesn’t help, also clear cache for “Bluetooth” under system apps. On iPhone, the equivalent is toggling Bluetooth off/on and, as a last resort, “Reset Network Settings” (note: this wipes saved Wi-Fi passwords too).
- Reinstall KS Fit. Delete the app, restart the phone, and install fresh from the official store. This clears corrupted pairing data the cache-clear doesn’t touch.
- Check for pad firmware updates. Some KS Fit versions offer firmware updates for the pad itself once connected — but if you can’t connect at all, this step has to wait. If you can connect intermittently, apply any offered firmware update immediately; it often fixes dropouts.
- Try a second phone. If one phone refuses to connect but another connects fine, the problem is the first phone’s Bluetooth stack or OS version, not the pad. This is a useful diagnostic before contacting support.
Phone-Side vs Pad-Side: Is It the Phone or the Pad?
If you’ve worked through the steps above and still can’t connect, this table pinpoints the culprit:
| Symptom | Likely culprit | Fix |
|---|---|---|
| App scan finds no devices at all | App permissions, or phone Bluetooth off/glitching | Grant location + Bluetooth permissions; toggle phone Bluetooth |
| Pad appears in scan but connection fails instantly | Another device holds the pad’s single BLE slot | Forget the pad on all other devices; power-cycle the pad |
| Connects, then drops within seconds | Stale cache, low phone battery (aggressive BT power saving), or distance | Clear cache; keep phone close; disable battery-saver for the app |
| Worked yesterday, fails today | A second device (tablet, partner’s phone) auto-reconnected | Turn off Bluetooth on other household devices and retry |
| App pairs but shows no data / can’t control | App version mismatch or incomplete pairing | Update the app; forget and re-pair from inside the app |
KS Fit App Compatibility Notes
| Topic | What to know |
|---|---|
| App name | KS Fit is WalkingPad/KingSmith’s official app (listed in WalkingPad manuals for the C1 and other models). If you see a similarly named app, make sure it’s the official KingSmith release. |
| New-device speed lock | New WalkingPad devices cap speed at 3 km/h until you walk 1 km or complete the novice guide in the KS Fit app. If your pad “won’t go faster,” that’s the lock, not a Bluetooth fault. |
| Child lock | The app’s child lock blocks all start commands. If the pad connects fine but won’t start, check this toggle — see our beeping-but-not-starting guide. |
| OS requirements | Keep your phone’s OS reasonably current; very old OS versions may lack the BLE features KS Fit needs. The manual’s advice stands: Bluetooth on, app updated. |
Safety: Power-Cycling Safely
This guide asks you to unplug and re-plug the pad a few times, so the basics matter:
- Unplug before touching anything under the deck. Never reach under the belt or into the motor area while the pad is plugged in.
- Let it sit 30–60 seconds between unplugging and re-plugging so the control board fully resets.
- Plug directly into a wall outlet during troubleshooting — flaky power strips cause brown-outs that look exactly like Bluetooth/pad faults.
- If you ever smell burning, see smoke, or see sparks during this process, stop immediately, unplug, and do not continue — that’s an electrical fault, not a pairing problem. The full stop-list is in the safety section of our beeping-but-not-starting guide.
WalkingPad App Connection FAQs
Why does KS Fit say “device not found” when Bluetooth is on?
Almost always one of three things: the pad isn’t powered on (it only advertises when powered), another device is already connected to it (remember: one client at a time), or the app lacks the location permission Android requires for BLE scanning. Work through steps 1–4 above in order.
I paired the WalkingPad in my iPhone’s Bluetooth settings. Is that wrong?
Yes — that’s a very common mistake. Remove (“Forget”) the pad from iOS Settings → Bluetooth, then pair from inside the KS Fit app’s own device screen. OS-level pairing can block the app from establishing its connection.
Can I use the pad with two phones (mine and my partner’s)?
Not simultaneously. Only one Bluetooth client can hold the connection. You can alternate — just make sure the other phone’s Bluetooth is off (or the pad is forgotten there) before the second phone tries to connect. Otherwise the first phone will silently grab the slot back.
The app connects but the belt won’t start. Is Bluetooth the problem?
No — if the app connects and shows live data, Bluetooth is working. A pad that connects but won’t start is almost always a child lock left on in the app, a missing safety key (on models that have one), or a remote/pad fault. Check the child lock toggle first, then see our beeping-but-not-starting guide and E06/E07 code guides.
Do I need the app at all? Can I just use the remote?
Yes — every WalkingPad works fully with the included remote; the app is optional. You only need the app to unlock the 3 km/h new-device speed cap, use the child lock, or track workouts. If Bluetooth is fighting you, the remote is a perfectly good daily driver.
KS Fit was working and suddenly stopped connecting after a phone update. What changed?
Phone OS updates sometimes reset app permissions or change Bluetooth behavior. Re-check KS Fit’s Bluetooth and location permissions after any OS update, and check the app store for a KS Fit update released to match the new OS version.
Conclusion
KS Fit Bluetooth failures come down to a short list: something else holding the pad’s single connection slot, stale phone-side Bluetooth data, missing permissions, or pairing from the wrong place (the OS menu instead of the app). Free the slot, restart both ends, grant permissions, pair from inside the app — and you’ll fix the overwhelming majority of cases.
If the app connects but the pad still won’t move, the problem has moved downstream: check the child lock and safety key, the remote, or the relevant error code guides.
