Maximum number of PIDs that can be read from the port?

[Vasanthi91]

Hello,

Is there a limit on the number of PIDs that can be read from the OBD port. I am able to add only upto 7 of them. The code tries to initialize in a loop upon adding more than 7 PIDs.

Please let me know what can be done.

Thank you.

If you need to read many PIDs, it is recommended to read one by one.
