Android uses a 128-bit key to set the network key. This is done to prevent listening in and stealing the private key.
The format the set network message is [size][msgID][network#][16 bytes key (128-bit)] where message ID is 0x76 and network# is 0, 1, or 2. NOTE: that this will overwrite the Public, ANT+, and ANT-FS default network keys until either a Reset command is sent, or the chip power cycles.
This feature is included with firmware AOV-1.06B05 or later.

1) The message protocol document (rev 5.0) refers to set the network key using message id 0x46 (with only 8 bytes of the key) and doesn't make any reference for the id 0x76 as you said before. Is that a hidden message id? Where can I find more info about that?
2) Is it possible to set only one channel to a private network while the other channels still using the public ANT+ network key? (I am asking that because I've noticed that SRM Power Control 7 can be paired with Sunnto belt and at the same time with other sensors using ANT+ public network).
3) I have tried to simulate a private network with AntWare II, but I can only set 8 bytes of the network key, so I couldn't find any difference. Does ANT+ provide any software to simlate that?
4) How do I know the AOV firmware version of my Xperia Live Walkman and Xperia Arc? Is it possible to know using your API?
