Erisin & Torque Pro can't be paired

[Dorchester2]

Sorry I should have said OBD2 you're right.
But no OBD2.
I'II try tomorrow without my phone. That may be a wise advice thanks a lot Roverlike.

How infortunate!
I need to be able to answer hands free if urgent so I need my phone connected.
And I would like to see ECU details on the screen as well if needed.

Hence the solution would be to be able to see phone screen on Erisin screen but that look difficult or impossible at the moment. Thus the next solution will be to upgrade Erisin to Android 12 and that would do the trick. However that looks another tricky challenge.

Anyway I'll try to connect Erisin to OBDII without my phone in the neighbourhood.

Screen mirroring does not work via Bluetooth protocol.

Screen mirroring can be enabled via WiFi network, so both your devices need to be connected to same WiFi network which you do not have in your car. Connection of phone and Erisin to 4G network means nothing. You cannot screen mirror by providers network.

Erisin do have WiFi, but I am not sure you can screen mirror over it to Erisin. That WiFi enables Erisin to connect to Internet.

In theory Bluetooth protocol enables ro connect several devices at same time. However only one device can work at one time unless special chipset is available on device. I did not see that on Erisin you have.

You can try to connect OBD2 and Phone and see if incoming call will interrupt OBD2 and you will be able to answer it and after that OBD2 ro continue to work.

Yes I knew that screen mirroring doesn't work by Bluetooth protocol.
It can work either via USB or via Wifi.
It's a doddle to do it with an Apple phone and it should work with an Android phone provided both devices have Android 12, which looks ridiculous because an Android device like Erisin and the like is based upon... Android!.
Unfortunately as I've said Erisin is based upon Android 10.

In Erisin, Wifi is working fine: it's the only way to connect it with my Orange box which allow Erisin to be connected everywhere via 4G+.

Anyway I've changed my mind so far: I'm very happy with Erisin, I can use WAZE & GPS, FM radios, USB memory stick (huge music play list, nearly 10 Go!) and hands free phone, which looks enough even too much when you're driving!
But I need to monitor the ECU, at least to have a short peep from time to time on coolant temperature, while the whole trip is recorded on the phone which is handy afterwards to verify a few other parameters.
So I'm to put back the phone bracket along the console with the short usb wire from the cigar lighter plug. Less stylish than I was hoping it to be but I can do with that.

Then no more headache at the moment. I'll see in the future whether some improvement is possible (Android 12) or not.
Thanks a lot for your much appreciated help and support Roverlike & Sjonnie.

To answer my own question and thanks to Roverlike advice, I assume that Erisin & Torque Pro can be paired provided your phone isn't already connected with the same Torque Pro to OBDII plug via Bluetooth.
But at the moment Torque Pro on the phone working fine with OBDII and dialoging with ECU in my 75 without any inconvenience, I'm no longer interested in doing further tests.
