Multiple device registration causes KID error #80

Open rashedtalukder opened 3 years ago

rashedtalukder commented 3 years ago

If the registration script is run for a second+ device after the first one, it results in a kid error due to the manifest handler only accepting 1 file in the output_files path. Solution is to 1/ reuse signer cert if it exists 2/ generate unique cert names using the serial number and match against manifest name.

deleting IoT thing and IoT certificate also works
