I guess it is not the right place to ask here for enocean specific details, but maybe I am doing something wrong by using serial connections and you can help me no matter if there is knowledge about this technology or not.

I have a problem to communicate with the RCM152 Module.

I have written a C++ program to communicate with the RCM152 by emulating packets of the PTM 200. I teach the RCM152 to listen to the following packets:

[06/19/12 04:21:44.546] INFO: SENDING BYTE : 55 <-- start byte

[06/19/12 04:21:44.546] INFO: SENDING BYTE : 00 <-- head begin

[06/19/12 04:21:44.546] INFO: SENDING BYTE : 07

[06/19/12 04:21:44.546] INFO: SENDING BYTE : 03 <-- 03 for send, 01 for receiver

[06/19/12 04:21:44.546] INFO: SENDING BYTE : ff <-- begin destination

[06/19/12 04:21:44.546] INFO: SENDING BYTE : ff

[06/19/12 04:21:44.546] INFO: SENDING BYTE : ff

[06/19/12 04:21:44.546] INFO: SENDING BYTE : ff <-- end destination

[06/19/12 04:21:44.546] INFO: SENDING BYTE : ff <-- Transmission quality (sender ff)

[06/19/12 04:21:44.546] INFO: SENDING BYTE : 00 

[06/19/12 04:21:44.547] INFO: SENDING BYTE : 10 <-- CRC Check

A PTM200 Device or a SG-FUS-24-230 Device are sending equivalent packets like:

I can control the device connected to the RCM152 like I want to with my sending packets (thats a good fact and means that the RCM152 has learned my packets and can use them. Also the actions (0x10 -> ON, 0x30 -> OFF) are working fine), but the problem is, that no matter which serial I choose, the RCM152 reacts to these packets. I only want to have actions if the teached-in serial is send and all other packets with different serials to be ignored. The RCM152 is not reacting to the packets sent by the PTM200 nor by the SG-FUS-24-230 because these are not teached-in. Thats exactly what I want to have with the packets created myself.

What am I doing wrong?

The libraries I am using are these for C++ http://pvbrowser.de/pvbrowser/sf/manual/rllib/html/

The enocean EEP says: For this purpose of a determined relationship between transmitter and receiver each transmitting device has a unique Sender-ID which is part of each radio telegram. The receiving device detects from the Sender-ID whether the device is known, i.e., was already learned, or unknown. A telegram with unknown Sender-ID is disregarded.
