Call Controlled Switch

Call Controlled LED

This example uses ACTION_EVENT_MT_CALL to toggle state of some connected switch. The first incoming call sets switch on, the second call off. And the cycle repeates.

Note:

It is attractive to the user because this control does not cost a penny. The call connection is not established.

Possible modifications:

• check incoming number and implement access list
• use timer or ACTION_STATUS to switch off after delay
