!SMSRETRY

Supporting chipsets:

• All

Set/return SMS retry period and interval

Configure the SMS retry period and interval for MO-SMS.

Usage:

• Execution: AT!SMSRETRY=<period>, <interval>

Response:

Purpose: Set the retry period and retry interval

• Query: AT!SMSRETRY?

Response:

!SMSRETRY:

Purpose: Return the current <period> and <interval> settings.

• Query List: AT!SMSRETRY=?

Purpose: Display the execution command format.

Parameters:

<period> (Number of seconds allowed for MO-SMS retry attempts):

• Valid range: 0–255

<interval> (Number of seconds to wait between MO-SMS retry attempts):

• Valid range: 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.
