Using the Particle Electron or Photon, the only way we can program it is if we put the device into DFU mode. The only way of doing this is:
Doing a button press combination on top of the Particle unit. This doesn't work for us, because we have a shield around the DUT because of high voltages we use in our tests
Plugging in a USB cable to the Particle Photon or Electron, then issuing:
"stty -f /dev/cu.usbmodem14101 28800" This puts it into DFU mode, allowing us to then program the device.
Unless the device is in DFU mode we cannot program it using the PLT's inbuilt programming capabilities. If there was a way of issuing such commands over the USB ports in the back of the PLT, then we could fully automate the process.
