My device is using the same version of the system, but I did not find this issue.
Please check the OBD device again and confirm that your OBD Category selection is correct.
Wait a little longer in the Bluetooth device search interface.
You can also try this Setup>System>APP>DUDU Launcher PRO>Storage & cache>CLEAER STORAGE.

    Set it up like this.

      We have found the problem, the reason is that FYT has a variety of Bluetooth configuration, you need to make changes to the Bluetooth configuration in order to read the Bluetooth information

        DUDU-HUANG I would like to connect a thermometer.. obd.. or something else to Bluetooth. in the launcher it does not see any device. other programs see it. is it possible to modify the Bluetooth setting for other devices without DuduOS? if so, can I ask for more detailed instructions on how to do it. I have only installed dudu luncher. My device is junsun v1 plus 8/256.

            Ok thank you. I have already seen this instruction. However, I have a problem as in the picture. I do not see any Bluetooth device. My device list is empty. This goes for both the xiaomi thermometer and OBD devices. The phone detects the devices. dudu luncher does not detect.

                          caolz same... I choose ELM327, but when try to search, the list is empty

                              I also facing same problem.. my obd2 vgate elm327 could not be found in dudu OS... but when connect to my phone it working perfectly just fine..

                                Because it has to have OBD2 as name. Else DUDU does not show it and can't connect to.

                                  If you still cannot find your OBD device, it may indeed not support this model of OBD device.

                                      Make a list of supported OBD dongles! I tested 3 dongles, none worked. ELM327 is a standard so it should be no problem to support all ELM327 dongles. It looks like a cool feature but doesn't work...

                                        It ist not just ELM327.

                                        It has to be named OBD2 or OBDII. Or else you can not pair it.

                                        You can try with your phone how the OBD dongle is named because you can pair everything with a phone, even nameless devices.

                                        Hi guys,

                                        I may have a solution for your problem. First, you have to tell what device you have. My solution was tested for 7862.

                                        1. Check with explorer /fem/app/ config.txt what value has in line sys.fyt.bluetooth. If you have it set to 0, then proceed to next step
                                        2. Get script for modifying bluetooth mod, is somewherw in the forum
                                        3. Modify lsec7862.sh and write value of 1 at the end of the line beginning with “sed -e ….
                                        4. Put everything along with config.txt on a clean pendrive and flash it.
                                          I had same problem, my blootooth device list was empty despite selecting elm327 category.

                                        Hope this helps,
                                        Cheers

                                        Can you find OBD devices in your phone's Bluetooth device list?
                                        Setup>System>Bluetooth, can OBD devices be found here?

                                          Well, if the OBD dongle has to be named OBDII, wouldn't be better to just remove this name filter from the device selection dialog? This will enable us to at least try some other and better dongles than those most and worst generic ones...
