Testing Commands (test)#

test commands#

test_dtm_end#

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.

C API#

/* Function */  
struct gecko_msg_test_dtm_end_rsp_t *gecko_cmd_test_dtm_end();  
  
/* Response id */  
gecko_rsp_test_dtm_end_id  
  
/* Response structure */  
struct gecko_msg_test_dtm_end_rsp_t  
{  
  uint16 result;  
}  

Command does not have parameters (for BGAPI headers refer to#

link)

Response Parameters (for BGAPI headers refer to link)#

Events generated#

test_dtm_rx#

Start a receiver test against a separate Bluetooth tester device. When the command is processed by the radio, a test_dtm_completed event is triggered. This event indicates whether the test started successfully.

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

C API#

/* Function */  
struct gecko_msg_test_dtm_rx_rsp_t *gecko_cmd_test_dtm_rx(uint8 channel, uint8 phy);  
  
/* Response id */  
gecko_rsp_test_dtm_rx_id  
  
/* Response structure */  
struct gecko_msg_test_dtm_rx_rsp_t  
{  
  uint16 result;  
}  

Command Parameters (for BGAPI headers refer to link)#

Range: 0-39

Channel is (F - 2402) / 2,

where F is frequency in MHz

uint8 | phy | PHY to use

Response Parameters (for BGAPI headers refer to link)#

Events generated#

test_dtm_tx#

Start a transmitter test against a separate Bluetooth tester device. When the command is processed by the radio, a test_dtm_completed event is triggered. This event indicates whether 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. The parameter phy specifies which PHY is used to transmit the packets. All devices support at least 1M PHY. A special packet type, test_pkt_carrier , 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.

C API#

/* Function */  
struct gecko_msg_test_dtm_tx_rsp_t *gecko_cmd_test_dtm_tx(uint8 packet_type, uint8 length, uint8 channel, uint8 phy);  
  
/* Response id */  
gecko_rsp_test_dtm_tx_id  
  
/* Response structure */  
struct gecko_msg_test_dtm_tx_rsp_t  
{  
  uint16 result;  
}  

Command Parameters (for BGAPI headers refer to link)#

Range: 0-255

uint8 | channel | Bluetooth channel

Range: 0-39

Channel is (F - 2402) / 2,

where F is frequency in MHz

uint8 | phy | PHY to use

Response Parameters (for BGAPI headers refer to link)#

Events generated#

test events#

test_dtm_completed#

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.

C API#

/* event id*/  
gecko_evt_test_dtm_completed_id  
  
/* event structure*/  
struct gecko_msg_test_dtm_completed_evt_t  
{  
  uint16 result;  
  uint16 number_of_packets;  
}  

Event Parameters (for BGAPI headers refer to link)#

Only valid for test_dtm_end command.
