The system will be reset after `OK` is sent. Note: If the input string contains multiple commands, the commands placed after `+RST` aren't executed. ### Operation type Execution ### Syntax | Command | Response | | --- | --- | | AT+RST | OK | ## AT+WRTMEM Source: [https://docs.qualcomm.com/doc/80-Y8730-10/topic/basic_at_commands.html](https://docs.qualcomm.com/doc/80-Y8730-10/topic/basic_at_commands.html) This command supports execution and set types: - Execution: Show command usage - Set: Set the specified value to the memory ### Operation type Set/Execution ### Syntax | Command | Response | | --- | --- | | AT+WRTMEM | +WRTMEM: <addr>,<size:1|2|4>,<value>

Before system sleep, a `lp_presleep` event is sent to the host. If the system fails to sleep, a `lp_sleepfail` event is sent to the host. ### Operation type Set/Execution ### Syntax | Command | Response | | --- | --- | | AT+DSLEEP | +DSLEEP=<1:AON timer wkup|2:Ext wkup>,<sleep duration in us(min 16000)>

This command also displays the time obtained from the NTP server. ### Operation type Query/Set/Execution ### Syntax | Command | Response | | --- | --- | | AT+TIME | AT+TIME: get usage of command



AT+TIME?: get RTC time

The `EVT:SYSCFG` response is sent out when the SSID or password is changed using the web server. ### Operation type Execution ### Syntax | Command | Response | | --- | --- | | AT+SYSCFG | +SYSCFG:<module>:<parameter1>:<parameter2>



OK | | N/A | +EVT:SYSCFG:<module>:<parameter1>,<parameter2> | ### Defined values - ``: Wi-Fi module - ``: SSID - ``: Password Last Published: Jun 03, 2026 [Previous Topic Introduction](https://docs.qualcomm.com/bundle/publicresource/80-Y8730-10/topics/qcc730_at_command_introduction.md) [Next Topic WLAN AT commands](https://docs.qualcomm.com/bundle/publicresource/80-Y8730-10/topics/wlan_at_commands.md)
