Page 30: Static Source Address Mode
By default, EMDCB uses static source addresses meaning that the source address is constant during normal operation. The structure of EMDCB static addresses is as follows: The upper 2 bytes of the source address are for EnOcean Bluetooth sensors always ◼ set to 0xE500 to enable filtering according to product type The lower 4 bytes are uniquely assigned to each device. -
Page 31: Resolvable Private Address Mode
So conceptually the IRK takes the role of the device source address while prand and hash provide a mechanism to select the correct IRK among a set of IRK. © 2024 EnOcean | www.enocean.com EMDCB User Manual | v2.0 | August 2024 | Page 31/56... -
