Murata WIT2420 - Connect Packet; Disconnect Packet (Base Only, Receive Only)

Handle 63 is reserved for broadcast packets from the base to all remotes. Acknowledgment
requests are not supported for broadcasts. For this reason, it is a good idea to send broadcast
messages several times to increase the odds of reaching all remotes.
3.1.3. Connect Packet
1110 1001 10HH HHHH RRRR TTTT 00NN NNNN <3-byte remote ID> (base, receive only)
H : handle number (0-62)
R : receive sequence number (from previous cell)
T : transmit sequence number (from previous cell)
N : network number of the previous base (if roamed)
1110 1001 10HH HHHH RRRR TTTT 00NN NNNN <3-byte base ID> (remote, receive only)
H : handle number (0-62)
R : receive sequence number
T : transmit sequence number
N : network number of base
Remotes must go through an automatic registration process when roaming from one base to
another, after loss of contact, or when acquiring a base signal for the first time after power
up. The base then assigns the remote a handle value, may or may not assign it a dedicated
time slice depending on the user settings, and notifies the user application of the new remote
with a connect packet.
The network number of the last base the remote was connected to is given to aid user
software in resending orphan packets that may have been sent to the remote's previous cell.
If the remote has been powered up for the first time and this is the first base contacted, the
last base ID will be reported as 80H.
3.1.4. Disconnect Packet (base only, receive only)
1110 1001 11HH HHHH 0111 1111
H : handle number (1-62)
When a remote goes out of range or roams to another cell, the base issues a disconnect packet
to indicate that the remote is no longer available.
