Supported PIDs - peetereczek - 11-22-2020

I found in OA log such line:

[2020-11-22 18:33:49.852030] [0x9829d140] [info]    [OpenAuto] [ObdDevice] query available pids result: SEARCHING...4100983BA013410098180001

Could anyone help me how I can understand from such line, what are supported PIDs by my car?

It is result of querying PID 00. More details about interpretation of the results can be found at https://en.m.wikipedia.org/wiki/OBD-II_PIDs#Service_01_PID_00

Ok,

But when I performed such query (for 0100) with Android app, I got:
7E8064100983BA013
7E906410098180001

I don't see relation to the Wiki page from the value returned in the OA log

We recommend to have a look at ELM327 documentation at https://www.elmelectronics.com/wp-content/uploads/2016/07/ELM327DS.pdf for more details. Response from your Android app contains ECU ID and size of the data. Bascially it is raw ELM327 response.

Response from Android App:
ECU ID   | Size of the Data (bytes)        | Queried PID    | Data
7E8      | 06                              |    4100        | 983BA013
7E9      | 06                              |    4100        | 98180001

Response from OpenAuto Pro logs:
Queried PID  | Data
4100         | 983BA013
4100         | 98180001

Format of the response depends on the startup commands that you send to ELM327. If you are using defaults from OpenAuto Pro configuration then responses from all ECUs will be combined to one. ECU ID will not be included in ELM327 response because of ATH0 command - more details about that command are available at page 18 of mentioned document.
