1. Modem_HW51_915_RHU.hex - firmware for RHU: Modem HW 5.1 used as the
   receiver of the IMU sensor fusion stream of the mobile beacon (hedgehog).
   Upload this firmware into a Modem HW 5.1 to use it as RHU

2. DFU - folder with the DFU file of the RHU firmware

Please don't upload the RHU firmware into the modem of the system - the system
needs both: the modem and the RHU

While the RHU is being updated, the Dashboard puts the hedgehogs to sleep and
wakes them up after the update
