 +====  RESET ====
 +
 +Reset (no additional data fields). No result will be sent.
 +
 +====  ALLOFF ====
 +
 +Turn everything off as if the power button would have been pressed (i.e. STM32 and radio). The CF won't be able to wake-up unless the power button is pressed. No result will be sent.
 +
 +====  SYSOFF ====
 +
 +Turn the STM32 off, but keep the NRF51 with radio awake. The CF can be woken up by: sending reset, pressing the power button, or sendind SYSON. No result will be sent.
 +
 +====  SYSON ====
 +
 +Turn the STM32 on. No result will be sent.
