The antenna load isexpressed in kOhm.14.3.2 SyntaxType Syntax Response ExampleSet AT+UANTR=[] +UANTR: ,load>OKAT+UANTR=0+UANTR: 0,10OKTest AT+UANTR=? +UANTR: (list of supporteds)OK+UANTR: (0)OK14.3.3 Defined valuesParameter Type Description Number Antenna identifier (optional parameter)• 0 (default value): cellular antenna• 1: GPS antenna (RFU) Number Measured value in kOhm of the antenna load with a resolution of 1 kOhm. The rangegoes from -1 to 53 (only integer values can be assumed), where:• -1: open circuit• 0: short circuit• 1: 1 kOhm (minimum limit of the measurement range)...• 53: 53 kOhm (maximum limit of the measurement range)14.3.4 Notes• The load resistor values below the minimum limit of 1 kOhm are identified as short circuit (load>=0), while values above the maximum limit of 53 kOhm are identified as open circuit (load>=-1).• The reported value could differ from the real resistance value of the diagnostic resistor mounted insidethe antenna assembly due to antenna cable length, antenna cable capacity and the measurementmethod.14.4 Power saving control (Power SaVing) +UPSV+UPSVSARA-R410M-52BModulesSARA-N4Syntax PIN required Settings saved Can be aborted Response time Error referenceAttributespartial No Profile No - +CME Error14.4.1 DescriptionSets the UART power saving configuration, but it has a global effect on the module power saving configuration:• If the power saving is enabled (+UPSV: 4), the UART interface is disabled after 6 s of inactivity and themodule enters the idle mode automatically whenever possible
