state

The state to reboot towards

Reboot the MCU Should not be called during flight or ciritcal operations.

• POWEROFF will go the deep sleep
• NORMAL will do a normal reboot (also to bootloader)
• FAST will try to skip the bootloader
• BOOTLOADER will try to keep the MCU in bootloader

  Parameters

  reboot_state

  The sate to reboot to
