1.5.1.5 VCC current consumption in low power idle mode (low power enabled)
The low power idle mode configuration is by default disabled, but it can be enabled using the AT+UPSV
command (see the SARA-R4/N4 series AT Commands Manual [2]).
When low power idle mode is enabled, the module automatically enters the low power mode whenever
possible, but it must periodically monitor the paging channel of the current base station (paging block
reception), in accordance to the 2G / LTE system requirements, even if connected mode is not enabled by
the application. When the module monitors the paging channel, it wakes up to the active mode to enable
the reception of the paging block. In between, the module switches to low power mode. This is known as
discontinuous reception (DRX) or extended discontinuous reception (eDRX).
Detailed current consumption values can be found in the SARA-R4/N4 series Data Sheet [1].
