DV (Secondary Antenna Function Switch)

This command applies to the XBee Smart Modem.

Set and read the secondary antenna function setting of the cellular component. When enabled, the cellular component uses both antennas to improve receive sensitivity.

This setting is applied only while the XBee Smart Modem is initializing the cellular component. After changing this setting, you must:

1. Use WR (Write) to write all values to flash.
2. Use FR (Force Reset) to reset the device.
3. Wait for the cellular component to be initialized: AI (Association Indication) reaches 0x00.
4. Use FR to reset the device a second time.
5. Wait again for the cellular component to initialize: AI reaches 0x00.
