gives 82d4 and not 80bb - to be investigated. FIXME
FIXME - what happens if PDM and POD is moved apart after the first two packages but before the ACK from the PDM, i.e. the ACK doesn't reach the POD within reasonable time ? How does the POD response to that ? Starts to beep and request a deactivation or?
