Does AT Interface application for Lyra include an RTOS?

Lyra 24Lyra

Answer

AT Interface is built on top of the Simplicity Studio bt_soc_empty application which is a basic BT template and does not include an RTOS. As the name implies, the application only provides the bare minimum to make a working Bluetooth application.
