Select an operating mode
The XBee Cellular Modem interfaces to a host device such as a microcontroller or computer through a logic-level asynchronous serial port. It uses a UART for serial communication with those devices.
The XBee Cellular Modem supports three operating modes: Transparent operating mode, API operating mode, and Bypass operating mode. The default mode is Transparent operating mode. Use the AP (API Enable) command to select a different operating mode.
The following flowchart illustrates how the modes relate to each other.
