1. A method for performing packet error rate (PER) measurement on a Bluetooth Low Energy (BLE) channel, the method comprising:
establishing an isochronous BLE connection between a test device and an implementation under test (IUT);
sending, by the test device, test data packets from the test device to the IUT;
receiving, by the test device, response data packets from the IUT, wherein a separate response data packet is sent from the IUT for each test data packet received by the IUT; and
measuring a PER on the established isochronous BLE connection between the test device and the IUT,
wherein the test data packets and the response data packets are transmitted in time slots of a predetermined time grid, and there is one or more empty data packets between a transmission of the a test data packet and a corresponding response data packet.
