Provisioning of multiple attached devices command

[CartBlanche]

Current process:

1. The meadow provision command is run on the command line and all devices in bootloader mode will be listed:

2. Selected which devices you would like to provision:

3. Confirm you want to proceed:

4. The specific firmware will be downloaded and each device will be flashed and updated sequentially:

5. If all goes well, all devices will have completed successfully

If a provision.json file is included in the same directory, where the command is run, the provision.json file should look something like this:

{
    "AppPath": "C:\\Users\\willo\\Downloads\\Blinky\\Debug\\netstandard2.1\\App.dll",
    "Configuration": "Debug",
    "DeployApp": "false",
    "FirmwareVersion": "1.12.2.0"
}

It will then use these settings for all attached devices and it will attempt to Deploy the App.dll, after trimming, from the path mentioned in "AppPath"

Tested on:

• Mac
• Linux
• Windows

TODO post v1.x Release:
Get this working in parallel. Currently there seems to be a conflict after the DFU process (Multi-OS flashing works fine) has finished and more than 1 device is connected, so the RunTime and ESP steps fail.

I like the tool, but I'm not certain it should be part of the main CLI - it feels like a separate tool to me.
