Hey guys,

I have a problem, when I query with TP2.0 higher measure blocks from a AXX engine in car.

An example of block 3 (everything works fine):
Code:
>0x740/1856 0x11 0x0 0x2 0x21 0x3 time:6921
0x300/768 0xB2 0x0 0x0 0x0 0x0 0x0 0x0 0x0 time:6922
0x300/768 0x21 0x0 0x1A 0x61 0x3 0x1 0xC8 0x0 time:6928
0x300/768 0x22 0x19 0x0 0x0 0x21 0xFF 0x3 0x1B time:6934
0x300/768 0x23 0x4B 0x80 0x5 0xA 0xB8 0x5 0xA time:6940
0x300/768 0x14 0xBA 0x25 0x0 0x0 0x25 0x0 0x0 time:6946

when I query block 0x82 (130 dec) I get a strange answer:
Code:
>0x740/1856 0x11 0x0 0x2 0x21 0x82 time:6954
0x300/768 0xB2 0x0 0x0 0x0 0x0 0x0 0x0 0x0 time:6959
0x300/768 0x11 0x0 0x3 0x7F 0x21 0x31 0x0 0x0 time:6975

What I found so far:
0x11 & 0xF0 => last packet
0x11 & 0x0F => expecting ACK
0x3 => 3 bytes payload
0x7F => negative response

How do I get to read this block?

any hints?

Cheers
jb

Yes, I have a hint. Look at the response to your reading of block 3. It not only contains the result of block 3, but also for block 130.
