BT (Guard Time Before) Parameter

<Non-AT Settable Parameter: AT Command Options> BT Parameter is used to set the DI pin silent

time that precedes the command sequence character (CC Parameter). By default, 1 half of a sec-

ond (500 milliseconds) must elapse before entering another character. The AT Command Mode

Sequence used to enter AT Command Mode is as follows:

"No characters sent for 1 millisecond [BT (Guard Time Before) Parameter]

"Send three plus characters "+++" [CC (Command Sequence Character) Parameter]

"No characters sent for 1 millisecond [AT (Guard Time After) Parameter]

All of the values in this sequence can be adjusted. AT Command is used to adjust the period of

silence that precedes the command sequence character.

Parameter Range: 0 - 0xFFFF (x 1 millisecond)

# of bytes returned: 2

Default Parameter Value: 0x1F4 (500 decimal)

Related Commands: AT (Guard Time After), CC (Commands Sequence Character)

CC (Command Sequence Character) Parameter

<Non-AT Settable Parameter: AT Command Options> CC Parameter is used to adjust the com-
