@ngocdh, It looks like from your screen shot that you got the particle serial monitor working okay.
It also looks like that VIN reader app flashed okay, since it is trying to read the VIN.
Usually, that is all it takes to get going...
Can you verify that your Photon is plugged into the Carloop securely?
Also, can you verify that the Carloop is plugged into the OBD2 splitter securely?
You could even try plugging the Carloop directly into the car without using the splitter.
Those checks all address potential connection problems. After that, I would suspect a problem with the Carloop or the Photon.
One thing that is strange from your screenshot is that "dhp" shows as offline when you do particle list, but the particle serial monitor is working. Do you have more than one Photon, or more than one particle account? Is the Photon named "dhp" plugged into the Carloop?
