<Oxx> Change breath data update rate

Allows the host to specify how often the Module sends a breath

data packet.

<Oxx> where xx (ASCII) is converted to a 8 bit binary number (yyzz

zzzz) with yy deﬁning how often the breath data is

updated.

If yy = 00 binary, Breath data packet update rate is deﬁned by

zzzzzz, where zzzzzz is in tenths of seconds. The 6

lower bits = (seconds × 10).

Odd values are rounded up

to even values.

If yy = 01 binary, Breath data packet update rate is every breath

where zzzzzz = doesn’t matter.

Exception: If the “no breath” condition occurs, data is sent

at 1 second increments.

If yy = 10 binary, Breath data update rate is when the data changes,

where zzzzzz = doesn’t matter.

Exception: If after 15 seconds the breath data has not

changed, data is sent after the next breath. This does not

guarantee a 15 second update; however, if the “no breath”

condition has occurred, the “no breath” timeout takes pre-

cedence.

Exception: If the “no breath” condition occurs, data is sent

at 1 second increments.

If yy = 11 binary, Not deﬁned.

Examples

<O05> send a breath data packet at .6 s interval (Odd values

rounded up)

<O40> send a breath data packet every breath

<O80> send a breath data packet every time the data changes

Special case:

<O00> no breath data sent (Note: Continuous CO

mode would

use this command.)
