No connection witz Samsung S21

Post by Finiss » Mon Mar 20, 2023 7:53 am

So far I have used my company phone (huawei P30 lite) for this app, without any problems. Now I had to switch to a Samsung S21. The OBD adapter has remained the same and the vehicle has not changed. On the S21 I can access the ECU with Torque. VAG DPF does not connect even after reinstalling several times. What can I do?

What exactly happens? It randomly works or never works?

It never works. Other Apps works with the ELM 327.
Also VAG DPF on my Huawei with this ELM 327 works.
But VAG DPF won't on my Samsung S21.

All Updates are installed. Torque connects fine. VAG DPF not.

Can you post a screenshot of the error?

I can only suppose an hardware compatibility issue between the adapter and the S21, but it's strange that other apps work.

Connection at Torque App to OBD works fine.
Connection at VAG DPF doesn't works.

It's strange because the error is for the first bluetooth connection with the adapter, before to try to communicate.

Was the adapter unconnected when you launched VAG DPF?
Can you see the adapter's data LED blinking during the connection procedure?

Dear Admin!
This is also the error on my Samsung galaxy A52S phone. The blue light flashes on the power adapter until it is connected, then it turns off.

If it connects then disconnects, should be an adapter related issue. You can understand that I can't give support for all not mine adapters.

I've seen something similar in the past, it was an issue due to instability of adapters while no communication moments, but fixable setting the communication delay to 0 in the options menu. After those reports I decided to set that parameter to 0 by default so you should have it already to 0. In this case I can only advise to move to a better quality adapter.
