What do I need to scan the QR code on the M404? I am trying my iphone's QR scanning app, but it doesn't recognize.

Also, is the device id available in the QR code? From what I read, it appears not.

It's not a QR code, but a data matrix.  
Orca Scan does the job, and most 2D barcode scanners should do the work too.  
You'll see both the serial number and the BLE Secret key returned.

[Cloud API reference | Reference Documentation | Particle](https://docs.particle.io/reference/cloud-apis/api/#look-up-device-identification-from-a-serial-number) will give you the DeviceID.
