Modes
The
IP (IP Protocol)
Cellular Modem.

API operating mode

API operating mode is an alternative to Transparent operating mode. API mode is a frame-based
protocol that allows you to direct data on a packet basis. The device communicates UART data in
packets, also known as API frames. This mode allows for structured communications with computers
and microcontrollers.
The advantages of API operating mode include:
It is easier to send information to multiple destinations
n
The host receives the source address for each received data frame
n
You can change parameters without entering Command mode
n

Bypass operating mode

CAUTION! Bypass operating mode is an alternative to Transparent and API modes for
advanced users with special configuration needs. Changes made in this mode might
change or disable the device and we do not recommended it for most users.
In Bypass mode, the device acts as a serial line replacement to the cellular component. In this mode,
the XBee Cellular Modem exposes all control of the cellular component's AT port through the UART.
Note
The cellular component can become unresponsive in Bypass mode. See
component in Bypass mode
When Bypass mode is active, most of the XBee Cellular Modem's AT commands do not work. For
example, IM (IMEI) may never return a value, and DB does not update.
When entering Bypass mode, the device terminates all existing socket connections. This includes the
Device Cloud connection if it is currently enabled. When leaving Bypass mode, the device re-
establishes a Device Cloud connection if the Device Cloud connection setting is currently enabled.
Command mode is available while in Bypass mode; see

Enter Bypass operating mode

To configure a device for Bypass operating mode:
1. Set the AP (API Mode) parameter value to 5.
2. Use AC (Apply Changes) or CN (Exit Command Mode) to apply the changes.
3. To verify that Bypass operating mode is active, query AI (Association Indication) and confirm
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:
