19.6AT^SSYNC Configure SYNC Pin

The AT^SSYNC command serves to configure the SYNC pin of the application interface. Please note that the SYNC pin may be assigned different functions: Depending on the design of the host application, the pin can either be used to indicate the current consumption in a transmit burst or to drive a status LED connected to the pin as specified in [2]. For detailed information on the SYNC pin and its LED functionality refer to [2]. Before changing the mode of the SYNC pin, carefully read the technical specifications.

Parameter Description

<mode>(num)

Operation mode of the SYNC pin. Setting is stored non-volatile.

0(D)

SYNC mode:

 

Enables the SYNC pin to indicate growing power consumption during a trans-

 

mit burst. You can make use of the signal generated by the SYNC pin, if power

 

consumption is your concern. To do so, ensure that your application is capable

 

of processing the signal. Your platform design must be such that the incoming

 

signal causes other components to draw less current. In short, this allows your

 

application to accommodate current drain and thus, supply sufficient current to

 

the GSM engine if required.

1

LED mode:

 

Enables the SYNC pin to drive a status LED installed in your application

 

according to the specifications provided in [2].

 

The coding of the LED is described in Section 19.6.1, ME status indicated by

 

status LED patterns.

2

LED mode:

 

Like <mode>=1, but, additionally, enables different LED signalization in SLEEP

mode depending on the status of PIN authentication and network registration. Please see AT+CFUN for details on SLEEP mode.
