CH (Channel) Command
<Networking {Addressing}> The CH
command is used to set/read the
operating channel on which RF
connections are made between RF
modules. The channel is one of three
addressing options available to the
module. The other options are the
PAN ID (ID command) and destination
addresses (DL & DH commands).
In order for modules to communicate with each other, the modules must
share the same channel number. Different channels can be used to
prevent modules in one network from listening to transmissions of
another. Adjacent channel rejection is 23 dB.
The module uses channel numbers of the 802.15.4 standard.
Center Frequency = 2.405 + (CH - 11d) * 5 MHz (d = decimal)
CN (Exit Command Mode) Command
<AT Command Mode Options> The CN
command is used to explicitly exit the RF
module from AT Command Mode.
CT (Command Mode Timeout) Command
<AT Command Mode Options> The CT
command is used to set and read the
amount of inactive time that elapses before
the RF module automatically exits from AT
Command Mode and returns to Idle Mode.
Use the CN (Exit Command Mode)
command to exit AT Command Mode
manually.
