Chapter 14 – Specific AT Commands

Ring Indicator Mode +WRIM

Description: This specific command sets or returns the state of the Ring Indicator Mode. In pulse RI mode, an electrical pulse lasting approximately 10µs is sent on the Ring Indicator signal just before sending any unsolicited AT response in order not to lose AT responses when client tasks are in sleep state. Still in RI mode, when receiving incoming calls, electrical pulses are sent on the RI signal.

In up-down RI mode, no pulses are sent before unsolicited AT response, and up-down signals are sent when receiving an incoming call.

Values:

<n>

 

 

0: up-down RI mode

 

 

1: pulse RI mode
