Transfer data

Transfer data via SD card

When you’re ready to process your data, you’ll need to transfer it from the device SD card:

  1. Disconnect the device from power (before extracting the SD card)
  2. Extract the SD card, insert it into your PC and open the LOG/ folder
  3. Transfer the folders/files you wish to process to your PC

Transfer data via 3G/4G

In addition to SD card transfer, the CANedge3 lets you auto-push data to your server via 3G/4G:

  1. Follow the guide to add a SIM card
  2. Follow the guide to set up your S3 server
  3. Configure the CANedge3 with your SIM card and S3 server details
  4. Power your device and use CANcloud to verify that files are uploaded to your S3 server [4]

Before you deploy your CANedge3 in the field, see our tips & tricks.

If you’re having trouble uploading files, see our troubleshooting section. For technical details, see the CANedge3 Docs. See also the server tools - e.g. to mount your server as a local drive.


We strongly recommend that you test your setup before remote deployment: Ensure that the device logs data, connects to your server and uploads files as expected[5]


When your device is connected to your server with OTA enabled, configuration changes made via the SD will be overwritten by the server Configuration File[6]

[4]When the device first connects to your server, it will upload the Rule Schema, Configuration File and Device File. When the device has finished recording a new log file to the SD card, this will be automatically pushed to your server as well. After a power cycle, it may take ~30 seconds for the 3G/4G module to start up and with some SIM cards it may take longer. The expected upload speed is 4-6 MB/min
[5]It is important that you test this in the actual location where you are installing your CANedge3. For example, mounting the 3G/4G antenna behind panels or in a box may block the connectivity/speed.
[6]Once your device is connected to your server, we recommend to update the Configuration File via your server (e.g. via CANcloud). If you prefer to update it via the SD card e.g. during tests, ensure that you delete the Configuration File from your S3 server device folder before making a change on the SD card (to avoid triggering an OTA update).
