Trouble communicating

[vilant]

The suspend/resume commands are not being sent. I'll try and explain what I think is happening and why.

During normal vehicle operation (i.e. when you're not data logging) the various modules that are connected to the ALDL bus* send and receive "chatter" frames. These frames contain status data that the modules need to share between themselves to keep the vehicle running properly.
* "bus" is just the name for the physical wires that connect all the modules.

The timing of the chatter messages are set up so that they don't collide with each other - i.e. only one message is transmitted on the bus at any given time.

When EFILive start data logging, it needs to send requests onto the bus and receive replies from the bus. All the timings we have been messing around with are really only to ensure that EFILive transmits its message when no other module is transmitting. If two modules transmit at the same time then their messages corrupt each other and neither message is delivered successfully.

The "frame checksum failure" message is the inevitable/eventual collision between a normal chatter message on the bus and an EFILive request/response for data message.

So you still need to configure the suspend/resume commands to actually work and to cause the other modules on the bus to stop sending their chatter messages.
That will require you to experiment with the module ID for the suspend/resume commands. Try all the values from $F0 thru $F5 for the module ID.

When I was datalogging everything seemed hunky-dory. I could see everything, MPH and RPM in sync with the actual vehicle readings (I assume the other readings were correct, there's just gauges that give a range not actual value on the car). The frame checksum failure probably happened when I started the car (forgot to press the stop icon, before I started the engine ). Do you think it works partially but it's not 100% yet? I didn't think I could datalog, if it was having suspend/resume command issues.

Whoops, I missed the whole "when your not datalogging part" I'll check tomorrow while the engine is off.

Ok, with the engine off I tried $F0-$F5 for the suspend/resume command. All were done with no reply, heartbeat-$F0,$56,$F1,$C9 ,T3-300, T5-50, T6-150 and Maxecho on. $F5 was the only one where I got Interface detected and Chatter detected. All the others were No Interface detected and Chatter detected. After I auto-detected chatter w/ $F5 and had both green lights, I hit start and got errors. Data would stream with $F1, and all the said settings, even though No Interface was detected, and I was able to datalog. Here's the info from the macro. I started with $F1, $F0, $F2, $F3, $F4, then $F5. What do you think?

Hi Paul,
Think this is it. Tinkered around and finally got both green lights and no errors. With the car off and the heartbeat= $F0,$56,$F1,$C9, suspend/resume=$F1, and set the times to T2=5, T3=160, T5=5, T6=17. Here's a section of what the serial I/O looked like

Pressed stop, turned off serial I/O, started the car and saw that the virtual dashboard was in sync with real one. I believe I should be good to go from now on right? You haven't seen anything of concern have you?

You haven't seen anything of concern have you?

That looks good - you're now officially an expert on ALDL communications

The interface cable is sending back a response so the connection from the PC to the interface box looks ok.
There appears to be no data from the vehicle. Check the connection from the interface box to the vehicle.

Sometimes the software gets confused by built in modems and if it connects to the modem accidentally then sometimes you get this same strange trace where the modem echoes back all the commands but nothing else.

Check in Windows device manager to see what COM port number your interface cable is using and make sure that is the same COM port number set up in the EFILive software properties setting.

Paul
