Bypass operating mode (DEPRECATED)

WARNING! Bypass mode is now deprecated and is not recommended for new designs. Direct access to the cellular module is not recommended or supported on the XBee Cellular CAT 1 Verizon model.

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. If you use this mode, you must setup the cellular modem directly to establish connectivity. The modem does not automatically connect to the network.

Note The cellular component can become unresponsive in Bypass mode. See Unresponsive cellular component in Bypass mode for help in this situation.

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. In this configuration, the firmware does not test communication with the cellular component (which it does by sending AT commands). This is useful in case you have reconfigured the cellular component in a way that makes it incompatible with the firmware. Bypass operating mode exists for users who wish to communicate directly with the cellular component settings and do not intend to use XBee Cellular Modem software features such as API mode.

Command mode is available while in Bypass mode; see Enter Command mode for instructions.
