BR/EDR - Enter DUT mode

Enter Device Under Test (DUT) mode for automated Bluetooth Classic (BR/EDR) testing controlled over the air by external test equipment such as a CMW270. This is the recommended way to test Bluetooth Classic as it uses a standard test protocol. It should be used instead of locally initiated tests if test equipment is available.

No additional parameters are required to enter Device Under Test mode.

Once in DUT mode the external tester can connect to the device and perform required tests.

BR/EDR - Locally Initiated Connectionless Constant Packet Transmit

The Constant Transmit (tx) test transmits a continuous stream of packets of the specified packet type and with specified data pattern at the maximum power allowed for that combination. Transmission occurs either in a hopping mode across all channels or on a single fixed channel. If the hopping mode parameter is specified, the channel value is ignored. If hopping mode parameter is not specified transmission occurs on a single channel. The maximum possible packet length is used by default.

Note: BR/EDR channel numbering follows standard Bluetooth Classic numbering, with channel 0 at 2402MHz through channel 78 at 2480MHz.

Continuous Transmit hopping across all channels, using packet type 3DH5 with a PRBS9 data pattern

BR/EDR - Locally Initiated Carrier Wave Transmit

The Carrier Wave (cw) test transmits a carrier wave at the specified frequency. The signal is modulated based on packet type if a type is specified, otherwise it is unmodulated.

BLE - Constant Transmit

The BLE Constant Transmit (tx) test transmits a continuous stream of packets using the specified PHY and with specified data pattern at the maximum power allowed for that combination. This is a standard test defined by the Bluetooth Core specification. The packet length is maximum by default, but may be adjusted. Test Mode must be set to LE to perform this test.

Note: BLE channels in btlru are numbered from 0-39, and sequentially map to 2MHz channels starting at 2402MHz. This differs from the official BLE physical channel index to RF Channel/frequency mapping.

The PHY types are specified with the -t parameter as follows:

Parameter Description
1 1M PHY
2 2M PHY
LR2 Long Range/Coded PHY, S=2
LR8 Long Range/Coded PHY, S=8

Note: The Sterling LWBx radios do not support the optional 2M and LR PHYs.
