Hibernation / Sleep Commands

This page documents AT commands for managing sleep, hibernation, and remote wake-up features in HaLow firmware 2.x modules.

Query:

AT+DSLEEP=?

Set Sleep Mode:

AT+DSLEEP=1

Response:

+DSLEEP:0
OK

Notes:

• In connected state: enters rest, sleep, and keep-alive mode
• In non-connected state: sleeps 60 seconds then wakes
• Cannot read parameters while in hibernation

Query:

AT+WAKEUP=?

Set Remote Wake-up:

AT+WAKEUP=11:22:33:44:55:66

Response:

invalid

*(if incorrect or STA not sleeping)*

Notes:

• Enter this command on the AP to wake a sleeping STA
• `mac_addr` = MAC address of target STA

* Use sleep mode to reduce power consumption in battery-powered applications. * Remote wake-up allows APs to wake specific STAs without manual intervention. * Always configure SSID, key, and networking before using sleep commands to ensure proper reconnection.
