Ah, well it would have been simpler to say that at the start ;)

I doubt that you can. For one thing, we don't know for sure that you even have a bluetooth transceiver: most SoCs these days include one, but without knowing the tablet's hardware we can't be certain. Even assuming that your SoC includes BT, there is no guarantee that all of the necessary signals will be connected if the manufacturer never intended to implement it. And even if all of the connections are there, you'd need radio firmware that supported it, and then a ROM that made use of the BT functionality.

There's more to this than finding and installing an app, or locating some "hidden" setting, I'm afraid.

I don't see any picture, but I don't think it will be easy. We'd need the exact model number to find the device: Depul is just a manufacturer, "din 2" probably just means 2 din connections, so there is more than one device out there that fits that description.

However, the truth is that there will only be an alternative ROM if the manufacturer has provided one, or if the device is sufficiently popular amongst Android enthusiasts that someone with the right skills has build one. The ROM must always be built for the specific device. And budget Chinese devices (which this seems to be) often get no updates at all from the manufacturer, so I cannot promise that we'll be able to find anything.

The main thing I've been able to work out so far is that the processor is probably the Allwinner A20. That does not include any wireless interfaces as far as I can see (and I've read the datasheet for the processor), so even the WiFi controller must be a separate component. I think that makes it very unlikely that the hardware supports Bluetooth, because you wouldn't buy additional hardware for BT if you didn't intend to use it.

Depends on whether the device has the necessary drivers. More likely if it supports USB OTG, but even then I'm not 100% certain.

I may have found the specs for this device: from the build number in your picture I think it may be this device. If so, and if that information is accurate, then it does have USB host capabilities, which sounds like OTG to me. But even if that is right I cannot guarantee that it will actually support an external BT dongle.
