???? Overview of the HJC9G BLE System


The Richmat HJC9G BLE is designed to be a control hub for adjustable bed motors. It often features:





  • Bluetooth Low Energy (BLE) connection for mobile control




  • Ports for head, foot, and massage actuators




  • Optional wired or wireless remote integration




  • Compatibility with the Richmat Smart Control app




  • Compact design for under-bed installation




When functioning correctly, the system enables intuitive and responsive bed adjustments. But issues can stem from pairing problems, wiring faults, or motor malfunctions.






???? BLE Control via Mobile App


The HJC9G BLE control box pairs with your smartphone through the Richmat Smart Control app. This app serves as the main interface for adjusting the bed and includes:





  • Up/down control for head and foot sections




  • Preset positions like Flat and Zero Gravity




  • Massage control (if equipped)




  • Memory save/recall functions




  • Light on/off toggle (if available)




Make sure your phone's Bluetooth is enabled, and you're within 10 feet of the control box when connecting.






????️ Common Issues and How to Diagnose Them


Below is a breakdown of the most frequent problems users experience with the HJC9G BLE system, along with tested solutions.






⚠️ 1. App Cannot Detect the Bed


Symptoms:





  • App shows "No device found"




  • BLE not showing in list




Causes:





  • Control box not powered




  • Bluetooth not enabled on phone




  • Already paired with another device




  • Signal interference




Fixes:





  1. Power cycle the bed – unplug it for 30 seconds, then plug it back in.




  2. Restart your phone and toggle Bluetooth off/on.




  3. Move your phone closer to the control box.




  4. If the bed was previously paired, remove the old connection in the app or phone’s Bluetooth settings.




  5. Reopen the app and retry scanning.







???? 2. Remote Not Responding


Symptoms:





  • Remote lights up but no bed movement




  • Bed works with app but not remote




Causes:





  • Lost pairing with control box




  • Battery depletion




  • Remote malfunction




Fixes:





  1. Replace the remote’s batteries (usually AAA or coin cell).




  2. Re-pair the remote:





    • Unplug power from the control box




    • Plug it back in and locate the pairing button on the control box




    • Press and hold pairing button until LED flashes




    • Press and hold any button on the remote for 5 seconds




    • LED will stop flashing if successful






  3. If it still doesn’t respond, try a new remote compatible with HJC9G BLE.







???? 3. Bed Doesn’t Move at All


Symptoms:





  • No motor noise




  • App and remote unresponsive




Causes:





  • No power to the control box




  • Damaged or unplugged motor cables




  • Internal board failure




Fixes:





  1. Verify the wall outlet is working (plug in a lamp or charger).




  2. Check the power adapter connection to the control box.




  3. Inspect cables connected to the head/foot/massage ports – ensure they are secure.




  4. Look for visible wire damage or pinched cables under the bed frame.




  5. If there's a fuse near the control box, inspect it and replace if blown.




If the system still won’t power on, the control box may need professional service or replacement.






???? 4. Some Bed Functions Work, Others Don’t


Symptoms:





  • Head moves but foot doesn’t




  • Massage works, but elevation doesn’t




Causes:





  • Partially disconnected motor cable




  • Burnt-out actuator




  • Port damage on the control box




Fixes:





  1. Disconnect and reconnect the affected motor cable securely.




  2. Swap the motor connections (e.g., plug head motor into foot port) to test whether the issue follows the motor or port.




  3. If a motor still doesn’t work in any port, it may be faulty and require replacement.




  4. If the port is dead, the control box might need replacement.







???? 5. Massage Not Working


Symptoms:





  • Vibration doesn’t start




  • Massage button unresponsive in app




Causes:





  • Massage motors not connected




  • Feature not supported on your bed




  • Defective motor or firmware issue




Fixes:





  1. Confirm whether your bed is equipped with massage motors.




  2. Verify motor connections under the bed.




  3. Use the app to trigger massage—if still unresponsive, the motor or control box could be defective.







???? 6. Memory Functions Not Saving


Symptoms:





  • Can’t save favorite position




  • M1/M2 buttons do nothing




Fixes:





  1. Adjust the bed to your preferred position.




  2. Press and hold the “M” button for 5 seconds until confirmation tone or light flashes.




  3. Tap M1/M2 to recall saved position later.




If still unresponsive:





  • Ensure your bed supports memory recall.




  • Try re-pairing the app or remote.
