2.2.4 Ping Pong Mode
In ping pong mode, the master and slave boards will flash one or two LEDs
with each packet (slave) or acknowledge (master) received, based on
message signal strength. In case there is a lot of other traffic on the default
channel, it is possible to change the channel.
2.2.5 Channel Changing (can only be peformed if boards have been
associated)
While in the ping pong mode, the current channel can be changed to one of
four other unique channels (five channels total). This is accomplished by
holding the push button for approximately two seconds, at which point the
green LED will be lit steady. Once the push button is released, the current
channel option number (one through five) is displayed by a series of flashes
on the red LED. Each short push button press will increment the channel
option number and display it with a given number of flashes on the red LED.
To accept the last selected channel, hold the push button until the green LED
goes out (approximately two seconds). After again releasing the button, the
device will return to the ping pong mode.
Note that both the master and slave devices must be set to the same
channel option number for the pair to communicate, and each board must be
individually set to that given channel option number.
