Dear Philipp, I could not find the code that you wrote on inside ZB4O nevertheless, it seems that all the call to the method ByteArrayOutputStreamSerializer.append_long(long) has never been used as far as I know, while it was used many time other method, so I think that the problem may be limited to the specified method. I will look further at it, but please can you point me to the file that contains the code that you posted? ---------------------------------------- Task #262: Check byte-order writing http://zb4o.aaloa.org/redmine/issues/262#change-680 Author: Philipp Buluschek Status: In Progress Priority: High Assignee: Stefano Lenzi Category: zigbee.zcl.library Target version: org.aaloa.zb4osgi.zigbee.zcl.library-1.X I implemented the writing of ZigBee data type IEEE_Address (see ZigBeeType.IEEEAddress) in ByteArrayOutputStreamSerializer. The original Java-data type was String, but I changed it to Long as it is much more adapted (as it's also what is returned from SimpleDriver.getIEEEAddress() ). Writing the IEEE Address (as a long) in ByteArrayOutputStreamSerializer, I supposed the code should look like: @ case IEEEAddress: final Long l = (Long) data; append_long(l.longValue()); break;@ But noticed that, the IEEE address gets written byte-order reversed over the air. In particular, the ZigBee Spec (1.2.1.3) says that the least significant byte must be sent first. But the implementation of Integers.writeLong() does the reverse (writes msb first to the buffer). For my case, I simply added a implementation of the reversed writing - so not a problem. But I now wonder - all other data types (larger than 1 byte) are written in the same manner as long in Integers.writeXXX(). Should they all be reversed? -- DO NOT ANSWER TO THIS E-MAIL ADDRESS, NO ONE WILL READ IT.
