Query List: AT!SMSRETRY=?
Purpose:
Configure the SMS retry period and interval for MO-SMS.
<period> (Number of seconds allowed for MO-SMS retry attempts):
<interval> (Number of seconds to wait between MO-SMS retry attempts):
Assume a retry attempt takes 2 seconds.
If <period> = 1 and <interval> = 8, and no attempts are successful:
Assume a retry attempt takes 2 seconds.
If <period> = 3 and <interval> = 5, and no attempts are successful:
Assume a retry attempt takes 2 seconds.
If <period> = 14 and <interval> = 5, and no attempts are successful:
Valid range: 0–255
Valid range: 0–255
Notes:
AT!SMSRETRY=<period>, <interval>
OK
Set the retry period and retry interval
AT!SMSRETRY?
!SMSRETRY:
<period>,<interval>
OK
Return the current <period> and <interval> settings.
Display the execution command format.
If <interval> is greater than <period>, a single retry attempt is made.
<interval> ignores the time spent actually performing a retry attempt.
If <interval> = 5, attempts are made at elapsedTime = 0, 5, 10, etc. until an
attempt is successful or <period> - elapsedTime < <interval>.
Time = 0: Retry attempt fails at time = 2. No more attempts are made
because <period> has expired.
Time = 0: Retry attempt fails at time = 2. No more attempts are made
because <period> will expire before the <interval> passes.
Time = 0: Retry attempt fails at time = 2; next attempt will begin at time=5
(the <interval> counts from the beginning of the previous attempt)
Time = 5: Retry attempt fails at time = 7; next attempt will begin at time=10
Time = 10: retry attempt fails at time = 12; No more attempts will be made
because the <period> will expire before another <interval> of 5 seconds can
pass.
