Understanding the HJH129B BLE Remote
Before diving into troubleshooting, it’s helpful to understand what the HJH129B BLE is and how it functions.
HJH129B BLE is a wireless hand control unit that communicates via Bluetooth Low Energy (BLE) with a compatible Richmat control box (often the HJC18 series).
It includes preset position buttons, massage control, and possibly USB charging ports depending on the model.
Designed for user convenience, it eliminates the need for wired remotes, but depends heavily on proper pairing and clean signal transmission.
Common Issues and Troubleshooting Steps
1. Remote Not Pairing with the Control Box
Symptoms:
Remote won't connect.
No LED indicator or blinking during pairing mode.
Functions are unresponsive even though the control box is powered.
Causes:
Pairing not initiated correctly.
Control box Bluetooth mode is off.
Signal interference or outdated firmware.
Fixes:
Restart both devices: Unplug the control box for 60 seconds and remove the remote’s battery (if accessible).
Re-enter pairing mode: Usually triggered by holding the "Pair" or "Head Down + Foot Up" buttons simultaneously until the LED blinks.
Clear old pairings: Some control boxes remember previous devices. Consult the product manual to reset Bluetooth memory if needed.
Distance and interference: Move closer and remove any metal objects between devices.
✅ Tip: Some models require pressing a button on the control box itself to initiate Bluetooth pairing. Refer to your specific manual.
2. Remote Is Paired, but Motors Don’t Move
Symptoms:
Remote connects, lights up, but bed or chair doesn’t move.
Motor makes a clicking sound but no action.
Causes:
Motor wiring is loose or disconnected.
Control box is malfunctioning or overloaded.
Incorrect port connections or damaged internal fuse.
Fixes:
Check all wiring: Inspect motor cables going into the control box. Ensure they’re firmly connected and undamaged.
Test manual controls: If you have a backup wired remote, try it. If the motors respond, the issue is with the BLE remote.
Check for overload: If you moved the bed/chair too frequently in a short time, thermal protection may have kicked in. Wait 15–30 minutes before retrying.
Control box reset: Disconnect power for a few minutes, then reconnect.
3. Specific Buttons Not Working
Symptoms:
Only certain functions (e.g., massage or “Flat” preset) don’t work.
Other buttons work normally.
Causes:
Button membrane wear or damage.
Software pairing mismatch.
Non-compatible control box (function not supported).
Fixes:
Verify function availability: Not all HJC18 control boxes support every feature the remote includes.
Re-pair the remote: Remove and re-initiate pairing in case of signal miscommunication.
Firmware update (if available): Some control boxes can be updated using a manufacturer app.
Try an alternate remote: If available, test the same function with a different remote to confirm hardware issue.
4. Remote Buttons Delay or Lag
Symptoms:
Pressing a button results in a delayed response.
Sporadic or laggy control, especially over longer distances.
Causes:
Low battery charge (if internal battery).
Interference from nearby wireless devices (Wi-Fi, phones, etc.).
Weak Bluetooth signal.
Fixes:
Charge the remote: If your model includes a rechargeable battery, connect it to a power source and let it fully charge.
Limit interference: Move away from routers or other Bluetooth devices while testing.
Reposition control box: Place the control box in a more open location for better signal.
5. Bluetooth Disconnects Frequently
Symptoms:
Random disconnects from the control box.
Device needs to be re-paired often.
Causes:
Software or memory conflict.
Remote or control box firmware incompatibility.
Weak or fluctuating power supply to the control box.
Fixes:
Update firmware (if your device supports OTA updates).
Use a surge protector to provide consistent power to the control box.
Factory reset remote: Hold down power and preset buttons simultaneously (if supported) for 10+ seconds until a reset occurs.
6. LED Not Turning On
Symptoms:
No light activity on the remote even when pressing buttons.
Remote appears completely dead.
Causes:
Battery failure or power circuit issue.
Internal hardware failure.
Broken LED (rare).
Fixes:
Charge the unit or replace the battery.
If still no LED after charging for 1+ hour, contact manufacturer or vendor—internal repairs may be required.
Maintenance Tips to Prevent Future Issues
Keep the remote dry – Moisture can damage internal components or short out the board.
Clean regularly – Dust or grime in button membranes can cause misfires or sticking.
Use as instructed – Avoid rapid button presses or excessive force that may damage the pad.
Update software – If the Richmat system is app-compatible, check for firmware updates through the official app or support page.
Keep a backup – Wired remotes or a second BLE remote can be helpful during issues or diagnostics.
When to Replace the Remote
Despite your best troubleshooting efforts, there are cases where the HJH129B BLE may need replacement:
Buttons are physically damaged or unresponsive despite clean contacts.
The internal battery no longer charges or holds a charge.
No Bluetooth signal is detected even after reset procedures.
Remote is cracked, submerged, or exposed to corrosive materials.
You can usually purchase replacement units through the bed manufacturer, online marketplaces, or mobility equipment suppliers—just be sure to match the exact model to ensure compatibility.
Conclusion
The Richmat HJH129B BLE remote is a convenient and essential part of your adjustable furniture system, but like all technology, it's susceptible to wear and glitches. With proper troubleshooting, many issues can be resolved without professional repair.
By following this guide step-by-step—from Bluetooth pairing to functional testing—you can likely identify the root cause of the problem and get your system running again. Always refer to your specific product manual when in doubt, and remember: when in doubt, unplug and start fresh.
