ELM327 Request more than 6 Bytes.

Hallo

Can anybody tell me how can I send a Request, that allowed more than 6 Bytes von ELM327 for the KWP2000 Protocol?

For example, I would like to send these Request:
2C F0 01 01 02 06 00 01 02 02 06 01 01 03 02 06 04


The Header is adjusted to
81 11 F1
with the Code "AT SH 81 11 F1"

The entire request should look like this
I know because I've logged with another tester with the Code "ATMA" and than show me this following Message

91 11 F1 2C F0 01 01 02 06 00 01 02 02 06 01 01 03 02 06 04 D5

When I enter the complete request, unfortunately I get only a question mark
The maximum length of the request is
2C F0 01 01 02 06 00 00



I also for command "ATAL" tried, without success. Or is there another command

It's a limitation of ELM327, you cannot send more than 8 bytes. Devices based on the STN11xx (e.g., OBDLink) do not have this limitation.

Thank you for your answer.

Is there no chance of anything else to make? Or is there another interface except for the ELM327 this do?

Yes, like I said OBDLink does not have this limitation. You can buy it from MP3Car (see the link in my signature).

Thanks Vitaliy

But can i send the ecu this command in 3 parts
for example
2CF00301020600
2CF00302020601
2CF00303020604

I´ve tried this but i doesn´t work :-(
Is this command not right?
