– Guard Time Before: Set/read required DI pin silent time before

the Command Sequence Characters of the Command Mode Sequence
(BT+CC_AT). The DI silent time is used to prevent inadvertent entrance
into Command Mode. The range is 0x0 to 0xFFFF.

CC

used between Guard Times of the AT Command Mode Sequence
(BT+CC+AT). The AT Command Mode Sequence causes the radio
modem to enter Command Mode (from Idle Mode).
The range is 0x20 to 0x7F.

AT

– Guard Time After: Set/read required DI pin silent time after the

Command Sequence Characters of the AT Command Mode Sequence
(BT+CC+AT). The DI silent time is used to prevent inadvertent entrance
into Command Mode. The range is 0x2 to 0x7FFC.

CT

– Command Mode Timeout: Set/read time period of inactivity (no

valid commands received) after which the radio modem automatically
