load structures used by EnOcean PTM 215ZE and PTM 535Z devices.
The following telegram types are used by these devices:
Data telegram
Commissioning telegram
The following security modes are supported by these devices:
Secure (authenticated) communication (using AES128 authentication)
Default mode on PTM 215ZE and PTM 535Z
Standard communication (without AES128 authentication)
Optional mode for PTM 535Z, not available for PTM 215ZE
Standard communication (without AES128 security processing) is supported as an optional
feature for PTM 535Z in case shorter payloads are desired for certain applications without
requirements for telegram authentication. This mode is not available for PTM 215ZE.
