A method for verifying a sensor system comprising a RF gesture sensor device and an application processor, the method comprising: transmitting, by a RF device of the RF gesture sensor device, an incident RF signal to a target; receiving, by a RF device of the RF gesture sensor device a reflected RF signal from the target, indicating information about a gesture of the target in three-dimensional space; and characterized by further comprising: transmitting by the RF gesture sensor device to the application processor over a digital interface (306, 406) digital sensor samples obtained from the received reflected RF signal; if a verification command is received by the RF gesture sensor device from the application processor: the digital sensor samples are not transmitted by the RF gesture sensor device to the application processor over the digital interface (306, 406) and a verification sequence having a predetermined quantity of repetitions of a predetermined random numeric sequence is transmitted by the RF gesture sensor device to the application processor over the digital interface (306, 406); the predetermined random numeric sequence is accessed by the application processor; the verification sequence received from the RF gesture sensor device correlated by the application processor with the accessed predetermined random numeric sequence; a quantity of correlations between the predetermined random numeric sequence and the received verification sequence is determined by the application processor; and a parameter of the RF gesture sensor device or the application processor is adjusted in response to the predetermined quantity of repetitions not equaling the quantity of correlations. transmitting, by a RF device of the RF gesture sensor device, an incident RF signal to a target;
