ESP-NOW ist using Espressif OUI 0x18fe34 at two positions:
------------------------------------------------------------------------------------------------------------
| MAC Header | Category Code | Organization Identifier | Random Values | Vendor Specific Content | FCS |
------------------------------------------------------------------------------------------------------------
and
-------------------------------------------------------------------------------
| Element ID | Length | Organization Identifier | Type | Version | Body |
-------------------------------------------------------------------------------
(found here: https://docs.espressif.com/projects/esp ... p_now.html)
The API just allows sending the Body. But it would be very important to send the Vendor Specific Content with an own IEEE-SA registered OUI.
Sending and receiving with an own OUI will simplify sorting out foreign ESP-NOW frames from other vendors and/or applications.
ESP-NOW, custom OUI
Re: ESP-NOW, custom OUI
"with an own IEEE-SA registered OUI."
you can simply use your own by using your own MAC - or doesn't this work for you?
btw: OUI
espressif has 208 entry just in time
best wishes

Re: ESP-NOW, custom OUI
If you're using a custom organization identifier (OUI) for peer addressing, the MAC address handling remains the same—each device still uses its MAC address (6 bytes) as the unique identifier, which can be customized based on your needs by specifying your OUI during peer addition. This feature can be beneficial when distinguishing between different networks or devices using ESP-NOW.
