Chapter 3 – Unsolicited AT Result Codes

General Indicator +WIND

Description: This is a general mechanism to send unsolicited non-standardized indications to the application. The identified unsolicited non-standardized indications are:

Indication during mobile originated call setup that the calling party is ringing.

Indication of the availability of the product to receive AT commands after boot.

The +WIND is overloaded with two functionalities:

1)posts non-standardized indications and

2)allows the user to specify indication level. For each of these indications, a “bit flow” has to be indicated.

Values:

<IndLevel>

 

 

1 (bit-0):

R-UIM Presence

 

2 (bit-1):

Reserved

 

4 (bit-2):

Reserved

 

8 (bit-3):

Indication that the product is ready to process all AT commands

 

16 (bit-4):

Reserved

 

32 (bit-5):

Reserved

 

64 (bit-6):

Network service available indication

 

128 (bit-7):

Network lost indication

 

256 (bit-8):

Reserved

 

512 (bit-9):

Reserved

 

1024 (bit-10):

Corrupted RF calibration values (checksum mismatch)

Note 1: If <IndLevel> is equal to 0, no unsolicited “+WIND: <IndNb>” will occur.

Note 2: If <IndLevel> bit 10 is set, the modem will transition to OFFLINE mode.

A combination (addition of the values) is used to allow more than one indication flow. 0 < In d Level ¡Ü 2047 For example: 128 (network lost indication) + 64 (network service available indication) = 192.

The response is OK if the values are in the previous range.

The unsolicited response will then be: +WIND : <event>

Example Result

The supported events are:
