Hello, I'm very new to arduino, currently waiting to receive the ESP32 module I ordered, so safe to say I haven't got the slightest clue what to do or how to proceed now. What im trying to do is use the esp32 to connect to my phone to stream music and hands free calls to a factory stereo that uses a J1850 VPW communication bus, so from what i gathered online, I need A2DP and AVRCP. What i need to do is be able to set up the esp32 in the first place, but i should be able to find a tutorial for that. the main bit is pairing the various AVRCP commands to the stereo buttons, I already know some of the hex commands that the bus sends when various buttons are being pressed, what i need to do is somehow translate the commands from the bus line to then be understood by the esp32 and then transferred over to the phone. the esp32 would also need to send a periodic idle signal (every 200ms i believe) on the bus to let the radio know it is present (as a cd changer), i think i can just copy and paste the actual line being sent from the cd changer in both idle and ready mode. id like to integrate the actual track time as well (i should have the hex data for that as well) but that is something that can wait for now. Bit long winded, apologies for that. Do I need any other board or circuitry other than the esp32, i saw a diagram from the j1850 vpw library, but honestly wouldnt have a clue where to start, id rather be able to just buy smth that can be coded, or if the code can be incorporated in the esp32
