BT Test Command
Description
bt_connectionless_dut_loopback_mode
COMx
Cypress equivalent command
mbt
connectionless_dut_loopback_mode
This command sets up a connectionless loopback
test with an external tester for analyzing both RX
and TX.
Once the connectionless command is entered, the
unit will prompt for the interactive arguments below.
Remote_Device_BD_ADDR: This is the BD_ADDR
of the remote transmitting device. [Size: 6 bytes]
LT_ADDR: This is the logical transport address of
the BT link. [Size: 1 byte] [Range: 0x01 - 0x07]
Number_Of_Tests: This is the number of tests to be
executed. [Size: 1 byte] [Range: 0x01 - 0x10]
The following arguments repeat depending on the
number of tests:
Retry Offset: When a timeout occurs, subtract the
offset to go back to the earlier test.
[Size: 6 bits {31:26} in little endian uint32]
[Range: 0x01 - 0x3f].
Number_Packets: This is the number of packets to
be received for this test.
[Size: 15 bits {25:11} in little endian uint32]
[Range: 0x01 - 0x7fff].
TxPowerIndex: This is the power table index to use.
[Size: 3 bits {10:8} in little endian uint32]
[Range: 0x00 - 0x07].
RxChannel: This is the frequency offset in MHz
from 2402 MHz.
[Size: 7bits {7:1} in little endian uint32]
[Range: 0x00 - 0x7f].
Packet Table Type: This defines the type of the
packet.
[Size: 1bit {0:0} in little endian uint32].
0x0: Basic Rate Packet Types
0x1: EDR packet types
Retry Time Out: This is the time required to retry.
[Size: 1 byte] [Range: 0x01 - 0xff].
Test Scenarios:
[Size: 1 byte].
0x0: RX-TX Loop Back Mode.
0x1: RX only with BER stats.
