Troubleshooting

Basic requirements

In order to get to the cause of any problems that may occur with the Resler module (or older Resler interface) and/or the I-BUS app, we require a few things in advance.

1. There is an original, orange Resler module (or black Resler interface) present
2. The module/interface has been correctly connected to the radio adapterAND to a USB port
   1. Installation instructions for Resler module and Resler interface
3. To use the I-BUS App, at least an OBC licence has been ordered from the I-BUS App Shop (not necessary if the module is to be used without the I-BUS App).
4. I-BUS app has been installed on a suitable Android device and is up to date (not necessary if the module is to be used without the I-BUS app).
   1. Download I-BUS app

  Resler Interface (Schwarz) and Resler Modul (Orange)

No Resler interface/resler module found

If the app cannot establish a connection to the Resler module/resler interface, this is due to the following reasons Problem initially only at the USB port.
The following things need to be checked:

1. Is the Resler Module/Resler Interface selected as "USB Interface" in the general app settings and is the USB connection active? (see picture below)
2. Which devices are connected to the USB ports of the radio?
   1. Please try another USB port first and disconnect other USB devices if necessary.
   2. The power supply of the USB ports is limited, known "power eaters" are: 3G/4G sticks, DAB+ sticks, CarPlay adapter with USB port for the smartphone, ...
   3. The USB ports are NOT intended and suitable for charging smartphones!
      
      
3. FDoes a USB data stick work on the USB port?
4. Does the problem only occur when it is particularly warm or cold?
5. Are the cables, plugs and PINs undamaged?
6. Is a TPMS (tire pressure display), iDrive controller (Arduino) or similar USB device used in addition to the Resler Interface/Resler Module?
   1. I-BUS App settings => general settings => open USB interface. Here the detected USB devices are shown, from I-BUS App v2.2.0.3 a numbered port is shown behind the device.
   2. optimally the Resler Interface/Resler Module is connected to the green USB (optional red USB) - Port 1 and the TPMS is connected to the yellow USB - Port 3 (from PQS-/IQ-series all USB ports are black and are called "Port 1")
   3. Close "USB Interface"
   4. Disconnect TPMS (or other detected device) from USB
   5. Open "USB Interface" again, the TPMS (or other detected device) should no longer be displayed.
      1. for the black Resler interface select "R.Resler IBUS Interface V6b Port: 1
      2. for the orange Resler module "Resler Module Port: 1" (or "USB Serial 2.0 Port: 1") select
   6. Close "USB Interface"
   7. Reconnect TPMS (yellow USB)
   8. Open "USB Interface" again
   9. the selected interface/module should still be set and a "new" USB device (e.g. TPMS) should be listed with "Port 3" but not show selected
   10. ready
7. if the orange Resler module is used, please check the firmware in the settings of the I-BUS App => "Resler module settings" ==> Resler module status".
   1. If an error appears here, please flash Resler Module manually

  USB Interface: Selection with port

If in the "USB Interface" list in the I-BUS App NO interface/module is shown

1. Please plug only the interface/module to a Windows PC (ideally Win 7 or Win 10).
2. The PC should " chuckle " and find a new device, if necessary install a driver for it by itself.
3. The interface/module is then listed either as "unknown device" or as "COM/LPT" device in the device manager (press Windows key + X). If more than one device is listed here: the device appears/disappears with connect/disconnect, so you can identify it.

NOTE: Since neither interface nor module is a storage device, it also does NOT appear in file manager. It can only be seen in the device manager.
Ideally you take a picture of this - we will ask for it.
If no device appears in the device manager, there is probably a defect. In this case, please contact the support via mail and ask for replacement.

No answer from control unit

If the app reports that it does not receive a response from the controller, this has two possible causes:

1. there is an error in the connection (usually the I-BUS line)
   1. Please connection according to installation instructions for Resler module and Resler interface check. Pay particular attention to the fact that:
      1. attention was paid to the correct PIN numbers and NOT to the cable colors
      2. a proper contact has been made (no power thieves, luster terminals, etc.)
         
         
2. there is a problem with the firmware of the orange Resler module:
   1. please flash Resler Module manually
      

No or restricted function of the Resler module (also in stand-alone mode)

1. Resler Module Mode check/set correctly in the I-BUS App / Resler Module Configurator
   

No access to the server

If the I-BUS app does not have access to the server, please check:

1. Is the I-BUS App up to date: 2.2.1.4 ?(state 2022-09-09)
   1. If necessary, download and install I-BUS app manually: www.ibus-app.de/app
      
      
2. Check the time setting in the Android setup. Only the time zone has to be set manually. The time itself is set automatically. Please do not set the time manually!
   
   
3. Please try another Internet access/hotspot or disconnect and reconnect the WIFI.
