Make command changes permanent
Send a WR (Write) command to save the changes. WR writes parameter values to non-volatile memory
so that parameter modifications persist through subsequent resets.
Send as RE (Restore Defaults) to wipe settings saved using WR back to their factory defaults.
Note You still have to use WR to save the changes enacted with RE.
Exit Command mode
1. Send CN (Exit Command mode) followed by a carriage return.
or:
2. If the device does not receive any valid AT commands within the time specified byCT
(Command mode Timeout), it returns to Transparent or API mode. The default Command mode
timeout is10seconds.
For an example of programming the device using AT Commands and descriptions of each configurable
parameter, see AT commands.
Transceiver modes
The following modes describe how the transceiver sends and receives over-the-air (OTA) data.
Idle mode
When not receiving or transmitting data, the device is in Idle mode. During Idle mode, the device
listens for valid data on both the RF and serial ports.
Transmit mode
Transmit mode is the mode in which the device is transmitting data. This typically happens when data
is received from the serial port.
Receive mode
This is the default mode for the XBee/XBee-PRO S2C 802.15.4 RF Module. The device is in Receive
mode when it is not transmitting data. If a destination node receives a valid RF packet, the
destination node transfers the data to its serial transmit buffer.
