Description

This interface provides access to extended signal quality information.

This interface will only be available once the modem is ready to be registered in the cellular network. 3GPP devices will require a valid unlocked SIM card before any of the features in the interface can be used.

Method Details

The Setup() method

Setup (IN  u rate);

Setup extended signal quality information retrieval.

Since: 1.2

IN u rate:

refresh rate to set, in seconds. 0 to disable retrieval.

Property Details

The "Rate" property

Rate  readable   u

Refresh rate for the extended signal quality information updates, in seconds. A value of 0 disables the retrieval of the values.

Since: 1.2
