|
|
This width, expressed in bytes, is used to determine the length of the
|
|
'tick' used to measure the time between observable changes to a
|
|
resource. A tick is expressed internally as GCOAP_OBS_TICK_EXPONENT,
|
|
which is the base 2 log value of the tick length in microseconds.
|
|
|
|
The canonical setting for the value is 3 (exponent 5), which results in
|
|
a tick length of 32 usec, per sec. 3.4, 4.4 of the RFC. Width 2
|
|
(exponent 16) results in a tick length of ~64 msec, and width 1
|
|
(exponent 24) results in a tick length of ~17 sec.
|
|
|
|
The tick length must be short enough so that the Observe value strictly
|
|
increases for each new notification. The purpose of the value is to
|
|
allow a client to detect message reordering withing the network latency
|
|
period (128 sec). For resources that change slowly, the reduced
|
|
message length is useful when packet size is limited.
