The network operation is supported on 16 upper channels in 2.4 GHz band, which are
numbered from
11(0x0B)
through
26(0x1A)
. Use
Tools/Send Command
window
to set channel mask. By default, current channel mask is displayed there (see Figure
8).
NOTE:
Channel mask is a bit field which defines the channels available. The
5 most significant bits (
b
27
,... , b
31
) of channel mask should be
set to
0
. The rest 27 least significant bits (
b
0
, b
1
,... b
26
) indicate
availability status for each of the 27 valid channels
(
1
= available,
0
= unavailable).
Figure 11. Setting channel mask dialog box
Open the
Channel bit mask
window by clicking the “
...
” button. Use checkboxes
to check the allowed channels (see Figure 11).
Figure 12 Setting the channel mask using checkboxes
When changing channel mask, coordinator sends the command to all of the nodes
and waits for 1 minute more after having received the last packet using old channel
mask. Next, coordinator forms the network on the new channel.
When channel mask command is being accepted by router or by end device the node
stops sending packets for 1 minute, and the
LED1
,
LED2
and
LED3
start blinking.
Next, it leaves the network and proceeds joining, using new channel mask.
