You can use a USB-UART tool and set the device address through HCI uart as follows:
1. Program the device with all 0xFF address with make target such as: demo.hello_sensor-CYW920706WCDEVAL download BT_DEVICE_ADDRESS=FFFFFFFFFFFF
2. Send Factory_Commit_BD_ADDR VSC (Vendor Specific Command) to set your own device address as: 01 10 FC 07 AA BB CC DD EE FF 00. Where the device is set to AA BB CC DD EE FF.
