<span><span style="font-size: 16px">(1) When it is off, it means that it is self-configuring or losing connection with the route.</span></span>

<span><span style="font-size: 16px">(2) When the 0.5S flashes, the wifi module is configuring the wif account and password.</span></span>

<span><span style="font-size: 16px">(3) 2S slow flashing means the configuration is completed, and the connection with the mobile phone is started.</span></span>
