What are the options for connecting an OBD2 adapter via Wi-Fi to a router?

Question

WiFi

Good afternoon!

I faced such a situation ... Not pleasant ... I am

actively preparing the car for a trip to the sea. Never traveled this far before. In addition to maintenance, I did a few more things:

1) I installed an external sufficiently powerful LTE MIMO antenna
2) I bought a USB modem
3) I bought and installed a router (I chose not very expensive, but which works well with USB modems and is powered by 12 volts - TP -Link Archer C6U)
4) And most importantly, and as I understand it fatal - I bought a Chinese 2DIN radio tape recorder on Android with good characteristics, in fact, ideal.

I initially checked the radio tape recorder at home, went to buy a power supply for 12 volt LED strips (I have 5 volt strips at home), but it will still come in handy on the farm. I checked everything that could be checked at the radio - the system, Wi-Fi, bluetooth, navigation, music. How does it react to ACC, illumination, turning on the rear camera. Everything worked and nothing boded trouble.

Joyful took the radio to the installation. They installed the radio tape recorder, gave the money, left, happy as an elephant.

The joy ended when I installed Torque Pro as a program for the on-board computer and tried to connect to the OBD2 adapter - nothing happened.

A lot of time has passed since that moment, the seller even managed to send a "branded" adapter, I have 3 pieces on hand. And I can't connect a radio to any of them.

At the same time, the radio tape recorder normally connects to the phone, even AptX turns on. All 3 adapters normally connect to the phone (of course, I turned off Bluetooth on the phone at that time).

Dropped to factory. The seller threw off the newer firmware, I also changed it. Including the MCU update.

Nothing helps...

And then I thought about the Wi-Fi version of the OBD2 adapter...
Unfortunately, you can't buy OBDLink MX Wi-Fi anywhere now, I saw only one option on the same Ali for 21 thousand rubles.. Tin ... It could connect to an existing network, and not be an access point like others ...

And now we finally come to the question in the title: "What are the options for connecting an OBD2 adapter via Wi-Fi to a router?"

I don’t understand networks very well, I see that the router must somehow connect to this device, and somehow forward a route to it in the local network.

Is it really possible to do this?

I'm ready to change the router ... The only question is ... Which one? I have heard a lot about Mikrotiki, and their powerful OS, and that you can do almost anything, at least 2, at least 3 providers at the same time ... I even thought about buying one for two providers when I was in Moscow ...

Or buy something extra, the question just now?

Help, tell me please, what can you think of in general in this situation ... Otherwise, it’s very sad ...

Answer 1

So did you end up connecting the adapter to the radio or not?
Take a router, put OpenWRT on it, or the same Mikrotik, create a Wi-Fi client on it and connect to your adapter without problems - this is a typical task.

Answer 2

The radio tape recorder did not connect to OBDII, even though it is an android, for one reason - it is itself a media device and a data receiver in the context of bluetooth. You can sacrifice the functionality of the radio and flash it with custom firmware, or change the configuration of the bluetooth device, it will not be possible to use the phone for pairing, but it will see other bluetooth devices by itself (it will be possible to play music from the radio to the radio).
It is possible to connect OBDII via Wi-Fi, although if the skill is not enough, then you will have to sacrifice the functionality of the router as a router, it will be connected to the OBDII whistle, and everyone will have to connect to it. How to put the Archer C6U adapter into the mode when it can be an access point and a host at the same time, well, I googled and didn’t find it, although I knew what to look for. You'll have to sacrifice.
Now, as a car enthusiast to a car enthusiast, what are you looking forward to seeing from OBDII on the road? What's not on the dashboard? For 13000 with a lining, I did not find anything useful for myself (amusing - I found a lot, for half an hour of joy). On the other hand, my OBD paid for itself thrice when it lay in the glove compartment, and then was pulled out into the light when necessary - with symptoms that needed to be checked. This is me trying to dissuade you from the geeky idea to screw the obd to the radio tape recorder.
There is something else. Your radio can be connected to CAN through an inexpensive adapter (or through a slightly rarer one to ISO), and if you are involved in the mystery of Java programming, you can do without OBDII at all, you can receive the same data directly from the bus, just to be able to interpret them.
