I tried using Tinker to test a small test unit but have been unable to install tinker on an Argon
I initially tried using the Particle app under IOS13. The Aron flashed magenta and after a short period restarted. It just sat there breathing cyan and the Particle App just kept circling around for ever.
I then tried Particle doctor with the Argon in DFU mode - it failed with the following
The Doctor didn’t complete successfully. Error writing firmware: file does not exist and no known app found.
VError: Error writing firmware: file does not exist and no known app found.

I have searched the board but have been unable to find any clues. I would appresicate advice as to the cause and remedy.
thanks
