Hi @all.

I've got the OBD2 KIT #1; all seems ok but the OBD doesn't connect;
I plug the usb or car AC > OBD blink blue for a second then stop on red > on the OLED:
"SDHC 8GB
OBD X
dfrobot X"

The OBD adapter is the "I2C Adapter"  and I've connected it to pin 4 (+) and 6 (-) of ICSP;
yellow > TX1; white > RX0 on Arduino

The TX led on arduino blink every 2 second but OBD is still in "X"

Any help?

Many thanks

Updated config and changed in nanologger.ino the line 268 to "recover();" as suggested by Stanley.

Now I've another problem, the arduino connect to my Toyota yaris, but don't connect to my Ducati wirh Marelli ECU (IAW5AM), that use the ISO9141-2 protocols

This protocol is supported from the OBD, but it doesn't.

Any help please!
