Local flash for Tracker One no longer working

Developer Tools Particle Workbench

I’ve been using the Tracker One (Model 402M) for a while and have been developing and flashing the devices locally through Workbench/USB.
Our most recent inventory of the Tracker Ones are Model 404M and I cannot flash these devices through USB.
I get the following error.

I’m using Device OS 3.2 and I am able to cloud flash these devices successfully.
Is there a configuration setting I need to change for local flashing?

Is the Tracker going into DFU mode, or is it in some other mode? The error indicates that there was no DFU device, but that could be caused by a number of things:

  • Device isn’t in DFU mode (blinking green or breathing cyan, for example)
  • Device is in sleep mode (LED off)
  • USB cable is a charging-only cable

If this is a brand new device and it’s stuck in blinking green you should activate the SIM first, because if a device is blinking green it may fail to go into DFU mode.

You also should make sure the version of Device OS is the version you are targeting in Workbench first. See the explanation here. Using Device Restore USB is a good way to do this.

Thanks - I will look into these settings and configurations.
