Is it possible to enable loopback mode on the LWB5+ Bluetooth for testing purposes?
The LWB5+ Bluetooth UART with HCI (Host Controller Interface) supports an internal loopback mode that can be enabled.
There are two loopback modes available for testing purposes: a Local Loopback Mode, and a Remote Loopback Mode.
These modes are defined in the BLUETOOTH CORE SPECIFICATION Version 5.4 | Vol 2, Part F, Section 8
To send HCI Bluetooth commands, you typically use a tool or library in your programming environment, such as hcitool or gatttool in Linux, or a library like PyBluez if you're using Python.
