I'm working on a obd2 project and need some help:
With the "at ma"
I get:
8A EA 29 20 A7 00 30
AA EB 60 20 A7 00 E7
E8 FF 10 03 B3
88 25 29 07 00 97
68 49 10 10 56 90
E8 FF 60 03 98
88 3B 10 43 80 0D
48 FF 40 06 03 AC
8A EA 40 A0 9E 50 26
AA EB 60 A0 9E 50 2E
8A EA 10 A0 8C 00 65
8A EA 10 20 8C 00 A5
88 53 10 04 C4
8A EA 10 A0 8C 00 65
4A EA 40 20 91 00 6B
48 FF 40 06 03 AC
What I need to do is find out which is the pid, data etc.
I have been looking at the " en.wikipedia.org/wiki/OBD-II_PIDs"
Can't make heads or tails :-(
Hi Anastasios,
Sorry it has taken so long to reply.
Have you tried any other real devices?
Is the device ELM327 compatible?
Maybe install a Bluetooth terminal App to make sure that you can talk and get a response.
Hello terryn, thank you for the reply.
My device connects with the elm327 device sends commands and receives bytes but nothing shows up in the gauges.
But when I connect my device with your desktop application everything works great.
Do you have any suggestions ?
Hi Anastasios,
The code that was provided was not complete, although it was tested on two OBDII devices and was OK.
The only thing you can do is log the input and output to ensure that the sent and received bytes are as expected, or use a terminal to do it manually.
I don't have enough time to restart the project at the moment. It may help you to strip the code down to the bare minimum and start from scratch.
