3.5.4.4.5. More Message to Send - +CMMS
+CMMS – More Message to Send
AT+CMMS=[<n>]
Set command controls the continuity of SMS relay protocol link.
Multiple messages can be sent much faster as link is kept open.
Parameter:
<n>
0 – Disable (factory default)
1 - keep enabled until the time between the response of the latest message send
command (+CMGS, +CMSS, etc.) and the next send command exceeds 1-5
seconds (the exact value is up to ME implementation), then ME shall close the link
and TA switches <n> automatically back to 0.
2 - keep permanently enabled (ME closes only the link after each send sequence,
<n> is not switched back to 0).
AT+CMMS?
Read command reports the current value of the parameter <n>.
AT+CMMS=?
Test command reports the supported value of <n> parameter.
