How do I control BLE Direct Test Mode with my LitePoint tester?
LitePoint provides application software known as IQfact+. IQfact+ is a test manager that runs on the PC and control both the tester and the DUT. The tester is controlled via Ethernet. For BLE applications, the most common method to control the DUT is through a 2-wire UART, so the PC normally has a USB to UART adapter.
IQfact+ support BLE “2-byte” commands (used by vendors such as Nordic) and “hci commands” used by vendors such as Dialog, TI, and many others.
