A new SetupThreshold() method is added to configure and control the device signal notifications sent to the host. RSSI and error rate based thresholds are initially assumed, but the interface allows growing the method with additional threshold types. Includes updates by Aleksander Morgado to improve documentation of the new methods and properties.

|
|
@short_description: The ModemManager Signal interface.
|
|
|
|
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.
|
|
|
|
There are two different ways defined to use the interface: either enabling
|
|
peridic polling (with the Setup() method), or configuring the device with
|
|
thresholds so that it reports the value updates automatically (with the
|
|
SetupThresholds() method, since 1.20).
|
|
|
|
Both Setup() and SetupThresholds() can also be used at the same time if
|
|
required, e.g. if they report different signal quality measurement types.
|
|

|
Setup:
|
|
@rate: refresh rate to set, in seconds. Use 0 to disable periodic polling.
|
|
|
|
Enable or disable the extended signal quality information retrieval via
|
|
periodic polling.
|
|
|
|
Polling is less than optimal; a better way to be notified of extended
|
|
signal quality updates is to configure the modem to trigger the reports
|
|
when the signal changes, i.e. with SetupThresholds().

SetupThresholds:
|
|
@settings: threshold values to set.
|
|
|
|
Setup thresholds so that the device itself decides when to report the
|
|
extended signal quality information updates.
|
|
|
|
The thresholds configured via this method specify the delta between
|
|
specific signal quality measurements that would trigger a report by the
|
|
modem. For example, the user may want to be notified every time the
|
|
signal RSSI changes more than 10dBm, so a value of 10 would be
|
|
configured as <literal>"rssi-threshold"</literal>.
|
|
|
|
The device may not support this kind of threshold setting, and instead
|
|
support fixed signal levels as thresholds (e.g. trigger reports when
|
|
signal RSSI crosses -90dBm). On these devices, the threshold configured
|
|
by the user as a difference between measurements is converted to fixed
|
|
signal levels automatically, depending on the expected range for each of
|
|
the configured values. E.g. if the user configures 10dBm as
|
|
<literal>"rssi-threshold"</literal>, the fixed signal levels could be
|
|
automatically set to -100dBm, -90dBm, -80dBm, -70dBm and -60dBm.
