The demo program will print the battery voltage, number of CAN messages and GPS position to the USB serial port.
To use it connect a Particle Photon or Particle Electron into your Carloop. Then go to the Particle Build online code editor. Go to the library section (bookmark icon), search for Carloop and click “Use this example”.
It looks like you might be using an older version of Particle’s firmware. Try changing your target device’s firmware to version 0.4.9 or later to be able to use CAN. In order to do so:
I’m finally getting started with this and when I click devices, it asks for a device ID. Where do I get that? Using the particle app, it tries to look for a Photon-XXX wifi ssid, but mine has a DUO-YWTS ssid. Is mine obsolete?
Hi,
New here. I followed the instructions for the demo app but unfortunately, I did not get any feedback from either a Photon or the Electron 3G. I tested with a Mercedes Benz w2003 and a Toyota Hilux D4D 2015 model.
I then went head and tried can-utils on a linux laptop as well but got nothing in the console when sniffing for packets.
Hey Katongo, have you confirmed that pins 6 &14 have CAN bus traffic on the OBD-II port? In other words, if you take a multimeter lead to one of them and the other lead to ground, what voltage are you getting?
If you are in fact on a CAN bus, you should see some traffic. However, there are some vehicle ECUs that only broadcast upon a “request” CAN message first. Here is a thread that will guide you on how to send those request messages: How to Request VIN - Software - Carloop Community
