testing commands (test)#

Commands#

test_dtm_end#

This command can be used to end a transmitter or a receiver test. When the command is processed by the radio and the test has ended, a test_dtm_completed event is triggered.

Event	Description
test_dtm_completed	This event is received when the command is processed.

test_dtm_rx#

This command can be used to start a receiver test. The test is meant to be used against a separate Bluetooth tester device. When the command is processed by the radio, a test_dtm_completed event is triggered. This event indicates if the test started successfully.

Parameter phy specifies which PHY is used to receive the packets. All devices support at least the 1M PHY.

The test may be stopped using the test_dtm_end command. This will trigger another test_dtm_completed event, which carries the number of packets received during the test.

Event	Description
test_dtm_completed	This event is received when the command is processed.

test_dtm_tx#

This command can be used to start a transmitter test. The test is meant to be used against a separate Bluetooth tester device. When the command is processed by the radio, a test_dtm_completed event is triggered. This event indicates if the test started successfully.

In the transmitter test, the device sends packets continuously with a fixed interval. The type and length of each packet is set by packet_type and length parameters. Parameter phy specifies which PHY is used to transmit the packets. All devices support at least the 1M PHY. There is also a special packet type, test_pkt_carrier , which can be used to transmit continuous unmodulated carrier. The length field is ignored in this mode.

The test may be stopped using the test_dtm_end command.

Event	Description
test_dtm_completed	This event is received when the command is processed.

Events#

test_dtm_completed#

This event indicates that the radio has processed a test start or end command. The result parameter indicates the success of the command.

After the receiver or transmitter test is stopped, the number_of_packets parameter in this event indicates the number of received or transmitted packets.
