WiFi access points

To enable WiFi data transfer in station mode, you’ll need a WiFi access point:

1. Select a WiFi access point for use with the CANedge2 (see below)

2. Add the WiFi access point SSID (name) and password in your Configuration File

3. Check if the device connects[1]

Access point options

There are multiple options that you can use as WiFi access points, depending on your use case:

Standard WLAN router: In “fixed locations” (warehouses, garages, mines, offices etc.) a WLAN router can be used as an access point. It’s popular in use cases where the CANedge2 is installed in a stationary application - or in e.g. garages where vehicles may return periodically.[2]

Smartphone: A simple option for e.g. test purposes can be a smartphone’s hotspot.

3G/4G WiFi router: You can use a 3G/4G router to allow the CANedge2 (with the S3 interface enabled) to upload data e.g. while on-the-road. For example, you can power a USB 3G/4G router via the CANedge2 2nd port. You can also deploy a cellular router to serve as a shared access point for several CANedge2 units that come within range periodically.

Note

If you’re using our 3G/4G USB router, follow our setup guide

If you are using the CANedge2 to connect to an S3 server, make sure the S3 details are added before testing the connectivity. The blue LED lights up when the device connects to the WiFi access point. The device will do so when it attempts to upload files or WiFi-sync the real-time clock. If the blue LED is not lit up, it can either be because the CANedge is not actively trying to upload files (e.g. if no log files are on the SD card) or if it is unable to connect to the configured WiFi access point. Note that for the S3 interface the CANedge2 will only attempt to connect if you’ve added your S3 details (and the device e.g. has log files to upload) or if it is syncing the RTC via WiFi. It can be difficult to direcltly use the WiFi LED to monitor proper connectivity - instead we recommend to evaluate this based on whether your files are correctly uploaded to S3

If you’re using a corporate WiFi network, make sure to check if e.g. firewalls may block connectivity. Further, potentially relevant ports may be blocked by default (e.g. port 80, 443, 123, 9000)
