What are the factory states for your Lyra DVKs and modules?

By default, our Lyra DVKs ship completely empty and erased with no bootloader and no application. Before getting started, please make sure to first program a bootloader and application image on your Lyra DVK.

All Lyra modules ship pre-programmed with our own Ezurio (formerly Laird Connectivity) bootloader type / configuration and a factory application. The bootloader enables firmware programming via Serial DFU (UART) on modules reset by triggering the BOOT pin and the factory application can be used to upload firmware over-the-air (OTA) via BLE for certain software options.

Please refer to our latest Lyra Series − Firmware Options and Upgrading User Guide document for more details about all available software options and firmware upgrade methods.
