SoftDeviceVariant

enum SoftDeviceVariant : Enum<SoftDeviceVariant> (source)

The Nordic SoftDevice an nRF52840 board's firmware is linked against. Static hardware fact, derived from the board's build.arduino.ldscript in meshtastic/firmware (nrf52840_s140_v6.ld / _v7.ld).

Load-bearing for factory erase: the erase images are linked for a specific application start address (0x26000 for 6.1.1, 0x27000 for 7.3.0) and the UF2 bootloader's write guard begins at MBR_SIZE (0x1000), so the SoftDevice region is writable. Flashing the 6.1.1 image to a 7.3.0 device erases the SoftDevice's last page, which needs SWD or serial DFU to recover. Never infer this value — an unresolved variant must refuse the operation.
