2. Send
to write the changes.
3. Send
to reboot the device.
4. After rebooting, enter Command mode and verify that Bypass operating mode is active by
querying
and confirming that it returns a value of 0x2F.
It may take a moment for Bypass operating mode to become active.
Leave Bypass operating mode
To configure a device to leave Bypass operating mode:
1. Set
to something other than 5.
2. Send
to write the changes.
3. Send
to reboot the device.
4. After rebooting, enter Command mode and verify that Bypass operating mode is not active by
querying
and confirming that it returns a value other than 0x2F.
Restore cellular settings to default in Bypass operating mode
Send AT&F1 to reset the cellular component to its factory profile.
USB direct mode
This mode allows you to replace the cellular component with the XBee Smart Modem such that the
USB lines are the same through a configuration option.

Enable USB direct mode
Set
to 7 to enable USB direct mode. When set to 7 DIO11/PWM1 (pin
7) brings out the USB D+ signal of the cellular component. The USB D- signal is available on pin 8. With
these pins connected to a USB host a direct connection is made to the cellular component which is not
mediated by the XBee processor.

Command mode
Command mode is a state in which the firmware interprets incoming characters as commands. It
allows you to modify the device’s configuration using parameters you can set using AT commands.
When you want to read or set any parameter of the device when operating in Transparent mode, you
have to enter Command mode and send an AT command. Every AT command starts with the letters
AT followed by the two characters that identify the command and then by some optional configuration
values.
