BT Test Command
Description
bt_radio_tx_test <bd_addr>
<frequency> <modulation_type>
<logical_channel> <bb_packet_type>
<packet_length> <tx_power>
Cypress equivalent command
mbt radio_tx_test
This command runs the connectionless transmitter
test.
bd_addr is the BD_ADDR of Tx device (6 bytes), for
example 00112233445566.
Frequency can be set to 0 to use a normal
Bluetooth hopping sequence or from 2402 MHz to
2480 MHz to transmit on a specified frequency
without hopping.
modulation_type sets the data pattern.
0: 0x00 8-bit Pattern
1: 0xFF 8-bit Pattern
2: 0xAA 8-bit Pattern
3: 0xF0 8-bit Pattern
4: PRBS9 Pattern
logical_channel sets logical channel to Basic Rate
(BR) or Enhanced Data Rate (EDR) for ACL
packets.
0: EDR
1: BR
bb_packet_type sets the baseband packet type to
use.
3: DM1
4: DH1/2-DH1
8: 3-DH1
10: DM3/2-DH3
11: DH3/3-DH3
14: DM5/2-DH5
15: DH5/3-DH5
packet_length can be from 0 to 65535. The device
will limit the maximum packet length based on the
baseband packet type. For example, if DM1
packets are sent, the maximum packet size is 17
bytes.
tx_power can be from
–25 dBm to +3 dBm.
