Abstract
A method of testing a Bluetooth low energy device over-the-air is described, wherein a Bluetooth low energy connection is established. An enable test mode command is transmitted to the device under test. The testing is started with transmitting at least one of a test transmission command and a test receiving command. Test radio frequency test physical layer packets are transmitted in a channel to be tested. A channel switching sequence takes place. At least one of a stop transmission command and a stop receiving command is transmitted once the intended testing on the channel to be tested has been completed. Further, a testing system is described.
Claims20
A method of testing a Bluetooth low energy device over-the-air, comprising:
- establishing a Bluetooth low energy connection between a device under test and a tester;
- transmitting, via the tester, an enable test mode command to the device under test to enable a test mode on the device under test;
- transmitting, via the device under test, an acknowledgement signal indicating that the test mode is enabled on the device under test;
- starting the testing with transmitting, via the tester, at least one of a test transmission command or a test receiving command to start a transmission testing or a receiving testing, respectively, wherein said transmission testing and/or said receiving testing relates to performing transmission and/or receiving measurements of the device under test;
- transmitting, via the device under test, an acknowledgement signal in response to the test transmission command received or the test receiving command received, the acknowledgement signal indicating that at least one of the transmission testing or the receiving testing is started successfully;
- transmitting, via at least one of the tester or the device under test, radio frequency test physical layer packets in a channel to be tested during a connection interval of the Bluetooth low energy connection;
- changing, when the duration of the connection interval is over, the channel to a next hopping channel;
- transmitting a continue command from the tester to the device under test when the testing in the channel to be tested is incomplete;
- receiving from the device under test as a response to the continue command at least one of a null in the transmission testing or a receiving report in the receiving testing;
- changing the channel to the channel to be tested since the continue command effecting that the Bluetooth low energy connection is maintained in the channel to be tested;
- and
- transmitting, via the tester, at least one of a stop transmission command or a stop receiving command once the intended testing on the channel to be tested has been completed.

A testing system for testing a Bluetooth low energy device over-the-air, comprising a tester with at least one antenna, the testing system being configured to:
- establish a Bluetooth low energy connection between a device under test and a tester;
- transmit, via the tester, an enable test mode command to the device under test to enable a test mode on the device under test;
- transmit, via the device under test, an acknowledgement signal indicating that the test mode is enabled on the device under test;
- start the testing with transmitting, via the tester, at least one of a test transmission command or a test receiving command to start a transmission testing or a receiving testing, respectively, wherein said transmission testing and/or said receiving testing relates to performing transmission and/or receiving measurements of the device under test;
- transmit, via the device under test, an acknowledgement signal in response to the test transmission command received or the test receiving command received, the acknowledgement signal indicating that at least one of the transmission testing or the receiving testing is started successfully;
- transmit, via at least one of the tester or the device under test, radio frequency test physical layer packets in a channel to be tested during a connection interval of the Bluetooth low energy connection;
- change, when the duration of the connection interval is over, the channel to a next hopping channel;
- transmit a continue command from the tester to the device under test when the testing in the channel to be tested is incomplete;
- receive from the device under test as a response to the continue command at least one of a null in the transmission testing or a receiving report in the receiving testing;
- change the channel to the channel to be tested since the continue command effecting that the Bluetooth low energy connection is maintained in the channel to be tested;
- and
- transmit via the tester at least one of a stop transmission command or a stop receiving command once the intended testing on the channel to be tested has been completed.
