Dear Receiver,

We know PSoC-63 has BLE functions. 

Moreover, does PSoC-63 have unique MAC address?!

Thank you so much.

@Tim_Shih ,

It is a common practice to use the silicon ID to create a MAC-equivalent address.

Note:  The silicon ID claimed to be unique-ish within a 10-year window of time.   Probably unique enough for most applications.

@Tim_Shih ,

MAC addresses only need to be unique on the network that the MAC-device is on.

If you're on a LAN, then having different devices with the same MAC address on different LANs is not a problem.

If you're on the WWW you really should have unique MAC addresses.  To do that you need to register with IEEE who administers MAC addresses.   They will assign you a manufacturer ID which is a part of the MAC address and will most likely charge you for the 1.68 million variants in the sub-numbers for your production assignment.

If you keep your BLE device on a LAN there are very rare instances where you'd ever need to have a IEEE-assigned MAC address.
