Can I run with Lyra multiple firmware options simultaneously?

No, this is not possible. Lyra does not support the execution of multiple firmware options at the same time. You can only program and run one single firmware option. This includes our own AT Command Set Interface firmware, Wireless Xpress or any custom BLE application which was developed with the Simplicity 5 Studio IDE and the Silicon Labs Bluetooth Stack.

You can switch between the individual firmware options at any time by simply reprogramming the Lyra module via the Serial DFU (UART) or Serial Wire Debug (SWD) debug interface. Please find additional information in our latest Lyra Series − Firmware Options and Upgrading User Guide.
