Credential questions

When you Blink Up a device does it clear the old WiFi credential and set the new ones, or does it add to the list of networks which it tries to connect to? I saw in the documentation that you can set multiple networks for the device to look for. But we just want the Blink Up credentials to be fresh every time.

BlinkUp clears the existing credentials and sets them to what was just configured.

The examples in the documentation show how to reconfigure WiFi credentials on the fly. When you do this, it’s equivalent to configuring the deviec with Blink Up (ie - you overwrite the current settings with the new settings, and those will persist across reboots, etc).
