Enable/disable GSM/GPRS Tx Burst indication

Enable use of DIO channel 1 (GPIO_0) to indicate an upcoming GPRS Tx burst. (GSM/

GPRS/EDGE mode only)

When enabled, the modem:

• Asserts the GPIO ~200 µs before a Tx burst starts. (Provides time for the host to

turn off peripherals before the burst.)

• Deasserts ~40 µs after the burst completes. (Provides time to ensure RF activity is

finished.)

Note: If DIO channel 1 has been programmed as an input or output using AT!DIOCFG,

the indication cannot be enabled.

Usage:

• Execution: AT+WTBI=<state>

Response: OK

Purpose: Enable/disable the Tx Burst indication.

• Query: AT+WTBI?

Response:

+WTBI: <state>

Purpose: Display the current indication state (enabled/disabled).

• Query List: AT+WTBI=?

Purpose: Display valid parameter values.

Parameters:

<state> (Indication state, stored in NV memory):

• 0=Disabled (Default)

• 1=Enabled
