Queries / sets SMS retry period and interval
This command is used to configure the SMS retry period and interval for MO-
SMS.
Usage:
• AT!SMSRETRY? returns the current <period> and <interval> settings.
• AT!SMSRETRY=? reports the format used for AT!SMSRETRY.
• AT!SMSRETRY=<period>, <interval> sets the retry period and retry
interval
Parameters:
<period> (Number of seconds allowed for MO-SMS retry attempts):
• 0–255
<interval> (Number of seconds to wait between MO-SMS retry attempts):
• 0–255
Note: If <interval> is greater than <period>, a single retry attempt is made.
Note: <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>.
Example 1:
Assume a retry attempt takes 2 seconds.
If <period> = 1 and <interval> = 8, and no attempts are successful:
• time = 0: Retry attempt fails at time = 2. No more attempts are made
because <period> has expired.
Example 2:
Assume a retry attempt takes 2 seconds.
If <period> = 3 and <interval> = 5, and no attempts are successful:
• time = 0: Retry attempt fails at time = 2. No more attempts are made
because <period> will expire before the <interval> passes.
Example 3:
Assume a retry attempt takes 2 seconds.
If <period> = 14 and <interval> = 5, and no attempts are successful:
• 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.
