ok thanks for the reply, I understand what you mean.
why it works with all smartphon apps. except with those I have described.
Thanks again

my interface is this.

good evening I'm new, thank you in advance because thanks to you I managed to change some interfaces.
I bought an elm327 v2.2 clone interface for a friend. not at the resistance between pins 6-14. but it does not work with Multiecu and alfaobd, with Torque or other yes. someone can help me.
thank you
