WiFi (CL3000)

CL3000 WiFi modes

The CL3000 supports three WiFi modes for remote log file access.

  1. Access point: Use e.g. a laptop to connect to the CL3000 like a WiFi access point (AP)
  2. Station: CL3000 connects to WiFi AP making the SD accessible by devices on the network
  3. Push: CL3000 connects to WiFi AP and pushes log files to an FTP server

By default, the CL3000 will operate in access point mode. You can change mode and other WiFi settings via the CONFIG.INI directly or via CANvas. For details, see the CLX000 Docs.

Access point and station mode

In access point and station mode, the CL3000 lets you access the SD card from your browser by entering the device IP or hostname (e.g. id0001/). Here, you can download, delete & split log files. Note that on some networks, you need to use the IP rather than hostname. Note also that the web user interface will only show up to ~500 log files (oldest files shown first).

Push mode

The push mode lets you auto-upload data to an FTP server. For example, you can set up an Exavault cloud FTP server or use your own local/dedicated FTP server.

Note

If you aim to use the ‘push’ mode at larger scale, we recommend to check out the CANedge2, the 2nd generation of the CL3000

WiFi tips & tricks

Below we list a few tips when using the CL3000:

  1. Use the CANvas ‘test’ buttons to verify your WiFi/FTP details before testing via the CL3000
  2. If uploading data via push mode, use a small split size (e.g. 1-10 MB) for smooth uploads
  3. If connecting multiple devices in station mode to the same WiFi AP use unique hostnames
  4. To auto-fetch log files from station mode CL3000 units, see for inspiration this Ruby script
  5. To access a CL3000 in station mode outside the WiFi network, you can port forward it
  6. For push mode local/dedicated servers, ensure that no firewalls block the access to the device
