Dedicated Commands

This document provides a list of dedicated serial commands (Command Line Interface) that can be used for debugging the GrowSpace Gateway Q1 device on-site or for directly modifying network/MQTT se

In This Guide

we introduce the serial commands that allow you to directly check or modify key settings of the GrowSpace Gateway Q1 device, diagnose network issues, and check the MQTT server integration status.

By connecting to the device through a terminal (such as Tera Term), you can enter the commands below to perform flexible debugging based on the on-site situation.

---

Operating Environment

Item	Description
Connection Type	USB Serial (COM port)
Software	Tera Term or similar terminal tools
Baudrate	115200
Input Method	Command waiting state after booting is complete

---

Basic Commands

Commands	Description
restart	System Reboot
basicSetting=	Set MQTT ID, password, IP, Wi-Fi SSID/password, and UWB PanID all at once
basicSetting?	View all the information entered above at once

restart

restart

The gateway will restart immediately. This command is used to apply settings after making changes.

Input Example

restart

Output Example

rst:0xc (SW_CPU_RESET), boot:0x13 (SPI_FAST_FLASH_BOOT)
configsip: 0, SPIWP:0xee
clk_drv:0x00, q_drv:0x00, d_drv:0x00, cs0_drv:0x00, hd_drv:0x00, wp_drv:0x00
mode:DIO, clock div:2
load:0x3fff0030,len:1184
load:0x40078000,len:13232
load:0x40080400,len:3028
entry 0x400805e4

---

basicSetting=

It allows you to set MQTT, Wi-Fi, and PanID all at once, and the input should be in JSON format.

Input Example

basicSetting={"mqttID":"testID", "mqttPW":"testPW", "mqttIP":"192.168.0.123", "wifiID":"testWID", "wifiPW":"testWPW", "panID":"0001"}

Output Example

✅ mqttID Saved
✅ mqttPW Saved
✅ mqttIP Saved: 192.168.0.123
✅ wifiID Saved
✅ wifiPW Saved
✅ panID Saved: 0001
🔁 After setting changes, ESP restarts
(The reboot log will be the same as the one from the restart command)

Notes

• Only 2.4GHz Wi-Fi is supported (5GHz is not supported)

• Changes are saved immediately and the device will automatically reboot

---

basicSetting?

This command allows you to check the currently saved MQTT, Wi-Fi, and PanID settings.

Input Example

basicSetting?

Output Example

{
  "mqttID": "testID",
  "mqttPW": "testPW",
  "mqttIP": "192.168.0.123",
  "wifiID": "testWID",
  "wifiPW": "testWPW",
  "panID": "0001"
}
