Jitter
This field displays the current quality of reception
◦ for the signal from the BHM if the BHS is registered.
◦ from any beacon if the BHS is scanning.
An acceptable link has a jitter value between 0 and 4 in Release 4.0 and later releases or
between 5 and 9 in any earlier release. However, to achieve the best link possible, the
alignment of the module should balance good jitter values against good RSSI values.
