Description: Establishing 2 connections (or more) and executing the Channel Sounding procedure between CC2745R10Q1(car) to CC2745R10Q1 or CC2340R53(key) devices. For 2 loops of connect-disconnect with 1000 CS loops in each connection. During the execution of the CS procedure enable, beginning at a specific loop iteration, the procedure fails with status 40 and no distance value is reported for the remainder of the test. After some time, the procedure enable done event is not received at all for certain keys (which may include one or more keys). Side effect: at the end of the test, when the car node is trying to disconnect from the keys (the keys are doing rest XDS), no link termination event is received.
