Thanks your answer :)

Now i can run all esp-idf example, spp_initiator and acceptor too.
But, when i run initiator, it lists all device around me with Name and with ADDRESS.
I see my odb reader too, its address: 00:80:98:25:CA:E8

Where should i change the example code to put this address.
I just ...

So should i upload acceptor file into an ESP32, and upload initator file to an other ESP32?
And they can communicate with each other.
Am i thinking right?

To be honest i want to connect and OBD reader (that has Bluetooth) with an ESP32, but esp must start communicate.
I cant upload a code into OBD ...

Hey guys, i want to solve same problem, is there any solving already?

Thank you.
