STK activation and deactivation still take effect after the device is restarted.
<proactive_command>
and
<terminal_response>
consist of the full BER-TLV data
object as defined in 3GPP TS 31.111.
For MU609, STK proactive commands can be divided into three categories:
Category 1: proactive commands that must be processed by the CAT client, including
DISPLAY TEXT, GET INKEY, GET INPUT, PLAY TONE, SELECT ITEM, SET UP MENU,
LANGUAGE NOTIFICATION, and LAUNCH BROWSER.
Category 2: proactive commands processed by the module (the CAT client is still notified),
including
SEND SHORT MESSAGE
,
SEND SS
,
SEND USSD
,
SET UP EVENT LIST
,
and
REFRESH
.
Category 3: other proactive commands that are processed by the module (the CAT client is
not notified).
Only commands of categories 1 and 2 are reported using the +CUSATP interface.
Only terminal responses to commands of category 1 can be delivered using the AT
interface.
