android headunit bluetooth issue

[botte_guy]

Hi, i have problem connecting with the obd2 using the original bluetooth app, it says that pin or incorrect key. But when i downloaded an app off playstore which could allows me to use my own pin (1234) i can connect to the obd with no problems at all. but when i open torque or obdlink app it tries to connect again using the original BT app which will then have the incorrect pin or passcode. My question here is how can i change my bluetooth default pin from 0000 to 1234? I'm using an android 7.0 headunit.,
