The proprietary %NBRGRSRP command reads measured Reference Signal Received Power (RSRP) values of neighboring cells. The command issues a valid response only when the modem is activated. v1.0.x v1.1.x v1.2.x v1.3.x
Neighboring cell measurements are valid and available only when neighbors are being monitored, which means that the strength and quality of the current cell signal do not meet the network configured level. For more information, see the requirements in 3GPP TS 36.304.
To save energy, nRF9160 does not search and measure neighboring cells for mobility purposes if the level and quality of the serving cell signal are above the thresholds defined by the network.
