I’m standing here with a device based on P1 that is out at a customers location. The device is blinking single red blinks, then some white. I have seen this before and the solution has been to run the Particle device doctor. The first step of upgrading the firmware goes fine and then this happens:
! System firmware update successfully completed!
Your device should now restart automatically.
Flashing the Device Doctor app
This app allows changing more settings on your device
Put the device in DFU mode
Tap RESET/RST while holding MODE/SETUP until the device blinks yellow.
? Select Continue when ready Continue
The Doctor didn’t complete sucesfully. Could not find serial device. Ensure the Device Doctor app was flashed
Please visit our community forums for help with this error:
And I’m thrown out into the command line. Note the second last line here. It cannot find a Serial device. If I open Serial Monitor, it finds the serial device as it should, but nothing happens on the Serial connection.
If I skip ahead a bit in the Doctor, I can also setup the wifi and I am also capable of Resetting server and device keys, but if I select “Configure IP address” I’ll get thrown out. The same goes for “Clear all data in EEPROM storage”.
I’m stomped. Anyone knows how I get around this?
