Class AdvancedSignal

Creates a Signal interface object for a provided Modem object. This provides "advnaced" detailed signal data from the modem.

Returns

Promise containing a new AdvancedSignal object

Since ModemManager 1.2

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().

Since ModemManager 1.20

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 "rssi-threshold".

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 "rssi-threshold", the fixed signal levels could be automatically set to -100dBm, -90dBm, -80dBm, -70dBm and -60dBm.
