KO Command – Low Power Mode / Sleep

Configure the system’s power saving mode to optimize battery life.

What is it for?

Use	Description
🔋 Battery saving	Reduces consumption when vehicle is off
😴 Sleep mode	Turns off GPS/GSM after inactivity period
⚡ Ultra low consumption	Extreme mode that even turns off CPU
⏰ Scheduled wake-up	Configure periodic wake-up cycles
🚗 Auto wake-up	Activates by movement or input changes

Description

Once configured, the device will only enter TOTAL SLEEP when the IGN value is zero. Both IGN connection and any activity on digital inputs will cause the device to “wake up” from power saving mode.

Syntax

Action	Command	Response
Configure	`SKOabbbbccccdddd`	`RKO...`
Query	`QKO`	`RKOabbbbccccddddeeeeffffgggg`

Parameters

Parameter	Description	Default
`a`	`E` = enabled, `D` = disabled	`D`
`bbbb`	Minutes for TOTAL SLEEP from REST	`0720`
`cccc`	Seconds to turn off GPS from IGN OFF	`0240`
`dddd`	Seconds for REST from IGN OFF	`0240`
`eeee`	Counter minutes for TOTAL SLEEP (read only)	-
`ffff`	Counter seconds to turn off GPS (read only)	-
`gggg`	Counter seconds for REST (read only)	-

Direct Actions

Command	Action
`SKO+`	😴 Force TOTAL SLEEP (if IGN is disconnected)
`SKO-`	🔄 Restart service, turn on GPS and GSM
`SKO++`	⚡ Force ULTRA LOW CONSUMPTION (includes CPU)

⚠️ Ultra Low Consumption Mode (SKO++): Can only be exited by impact sensor movement detection or G-force.

Associated Triggers

Trigger	Indicates
`KO00+`	Total sleep mode active
`KO01+`	Rest state active
`KO02+`	Full on mode active
`KO03+`	KO mode enabled
`KO04+`	KO++ mode inactive

Extended Ultra Low Consumption Mode

Variant of ultra low consumption mode that allows configuring periodic wake-up.

Extended Syntax

Action	Command	Response
Configure	`SKO++aaaabcdefg`	`RKO++...`
Query	`QKO++`	`RKO++aaaabcdefg`

Extended Parameters

Param	Description	Values
`aaaa`	Time to wake up	Seconds (`0000` = never). Prefixes: `m` = min, `h` = hours
`b`	Wake up by movement	`1` = yes, `0` = no
`c`	Wake up by inputs	`1` = yes, `0` = no
`d`	Cellular modem	`1` = on, `0` = off
`e`	GPS module	`1` = on, `0` = off
`f`	Internal source	`1` = on, `0` = off
`g`	External source 3.3V	`1` = on, `0` = off

Examples

Enable basic low power mode


>SKOE072002400240<     // Enable KO: 720min sleep, 240sec for GPS off and rest
>RKOE072002400240;ID=037883;*5A<

Force total sleep


>SKO+<                 // Force sleep mode (requires IGN=0)
>RKOK;ID=037883;*5A<

Low consumption cycle with periodic reports


>SRL01E;TRG=GPS+;ACC={GBR00L}<           // On GPS acquisition, generate report
>SRL02E;TRG=BU-;ACC={SKO++0060001000}<   // On buffer empty, enter KO++ mode

In this example:

When GPS position is obtained → generates BR type 00 report
Once buffer is downloaded → enters ultra low consumption mode
After 60 seconds → automatically wakes up and repeats the cycle
