Description:

WiCAN is a OBD-II WiFi/BLE to CAN adapter based on ESP32-C3, it's a great tool for car hacking. The original firmware can interface directly with RealDash over WiFI or BLE. Realdash allows you to create your own custom dashboard with stunning graphics, it's available on ANDROID, IOS AND WINDOWS 10.It can connect to your existing WiFi network or any device can connect to it's WiFi access point.

WiCAN also works with BUSMaster, for monitoring and logging CAN bus traffic.

Also available API for LabView, C#, VB.Net, Delphi, Python - In case you're writing your own software.

WiFi and CAN configuration can be set configuration web server. Documentation.

Note: Firmware source code available on github

Programming Examples

Configuration:

1. WiFi/CAN Configuration:

1. Power up the device using the USB cable, or by plugging into the OBD-II connector.
2. The blue LED will light ON, and a WiFi device access point will start. The SSID will look like: WiCAN_xxxxxxxxxxxx
3. Connect to the SSID using the default password: @meatpi#
4. Using a web browser, go to http://192.168.80.1/
5. The status menu shows the device current configuration, if in Ap+Station mode it will show the device IP on your local network if connected successfully.
6. The WiFi menu lets you configure the WiFi parameters. It is recommended that you change the AP access point.
7. The CAN menu allows to choose the protocol set the bitrate and TCP/UPD port number.
8. When ready click submit Changes button and the device will store the configuration reboot immediately.

2. BUSMaster

You need to download the right version of BUSMaster provided in this Link. Here is how to setup the hardware.

Device Configuration:

1. Go to configuration webpage.
2. Baudrate can be set in BUSMaster configuration
3. Set "Port Type" = TCP
4. Set "Protocol" = slcan
5. Click submit changes.

BUSMaster Configuration:

1. Select VSCom CAN-API by clicking on 'Driver Selection -> VSCom CAN-API"
2. Then Click on 'Channel Configuration -> Advanced'
3. Fill in the IP and port. Example: 192.168.80.1:3333
4. Check the 'Hardware Timestamps' check box.
5. Choose the Baudrate.
6. Click 'OK', then Click the Connect button on the top left corner.

3. RealDash

WiCAN can connect with RealDash using WiFi or BLE. The Protocol and CAN bitrate must be set using the configuration page. BLE is only support on Android and IOS. Windows 10 only supports WiFi connection.

WiFi Device Configuration:
