Appendix A – GSM/GPRS +WIND Command

Multi-Tech Systems, Inc. IP Connectivity AT Commands for GPRS-F4 Wireless Modems (PN S000437C) 41

Appendix A – GSM/GPRS +WIND

Command

General Indications +WIND

Description: This command provides a general mechanism to send unsolicited non-standardized

indications to the application. The indicators are:

• Indication of a physical change on the SIM detect pin from the connector

(meaning SIM inserted, SIM removed)

• 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.

• NITZ indication (Network Information and Time Zone)

For each of these indications, a “bit flow” has to be indicated.

Values: <IndLevel>

0 No unsolicited “+WIND: <IndNb>” will occur. Default.

1 (bit-0) Hardware SIM Insert/Remove indications or SIM presence after

software reset.

2 (bit-1) Calling party alert indication.

4 (bit-2) Product is ready to process AT commands (except phonebooks,

AOC, SMS), but still in emergency mode.

8 (bit-3) The product is ready to process all AT commands at the end of init

or after swapping to ADN in case of FDN configuration

16 (bit-4) A new call identifier has been created (after an ATD command,

+CCWA indication)

32 (bit-5) An active, held or waiting call has been released by network or

other party

64 (bit-6) Network service available indication

128 (bit-7) Network lost indication

256 (bit-8) Audio ON indication

512 (bit-9) SIM phonebooks reload status

1024 (bit-10) SIM phonebooks checksum indication

2048 (bit-11) Interruption indication (only if FTR_INT is activated)

4096 (bit-12) Hardware rack open/closed indication

8192 (bit-13) NITZ indication

16384 (bit-14) SMS service ready indication

Combination (addition of the values) is used to allow more than one indication

flow: 0 ≤ IndLevel ≤ 32767

• To activate a specific WIND indication, <IndLevel> must have a value

described above.

AT+WIND=16384 only activates SMS service indication.

• To activate several WIND indications, <IndLevel> must have a value

just before the last indication required.

AT+WIND=32767 all unsolicited indications.

<event>

0 The SIM presence pin has been detected as “SIM removed”

1 The SIM presence pin has been detected as “SIM inserted”

2 Calling party is alerting

3 Product is ready to process AT commands (except phonebooks, AOC,

SMS), at init or after AT+CFUN=1

4 Product is ready to process all AT commands, end of phonebook init or

swap (FDN to ADN)

5 Call <idx> has been created (after ATD or +CCWA…)
