Indicator light:

• 1.When No equipment is connected, the indicator light is Green fast flashing.
• 2.When there is device access, the indicator light is steady green.

Instructions:

• 1.When switching to the AP mode, the device will start the AP hotspot ATOM_PRINTER_XXXX, and the user can use a mobile phone or computer to directly connect to the AP (without password).
• 2.After the connection is successful, the connected device will automatically pop up the configuration page. You can directly enter the content on this page to print text, two-dimensional code, and one-dimensional code content.
• 3.At the bottom of the page is the WiFi configuration option, through which you can configure the device to connect to the specified WiFi and switch to work in MQTT mode.

MQTT mode

Indicator light:

• 1.When WiFi connection failed, the indicator light is Red flashing quickly.
• 2.When the WiFi&MQTT server is not connected, the indicator light is blue fast flashing.
• 3.When the WiFi&MQTT server has been successfully connected, the indicator light is steady blue.

Instructions:

• 1.Before switching to MQTT mode, you need to configure WiFi information for the device through the configuration page of AP mode. After completing the configuration, the device will automatically restart and enter MQTT mode.
• 2.If there are multiple times of WiFi connection failure, you can press the middle button of ATOM to switch to AP mode and reconfigure WiFi information.
• 3.After successfully connecting to the MQTT server, ATOM Printer will automatically print out the subscribed Topic information (Topic is the Mac address of the device).
• 4.Users can connect to mqtt through [UIFlow](https://flow.m5stack.com/) or other tools (such as [EMQ MQTT Tools](http://tools.emqx.io/)). m5stack.com (port 1883). Distribute Topic content corresponding to ATOM Priter device to realize remote printing.
