First boot

Assuming you've successfully Downloaded and Flashed the unispa software on your ESP8266, your device may perform the following actions upon the first boot:

1. Full File system format and Factory reset, indicated by the glowing on-board LED. This may take up to 10 minutes, so do not disconnect or reset the device during this phase. You can avoid this by selecting the factory install option when uploading the firmware.
2. Once the File system is ready and the Factory reset is complete, the device will boot up, indicated by 10 fast flashes of the on-board LED.
3. Following the first boot, the device will run without any wireless connection, indicated by a single flash of the on-board LED every 10 seconds. However, it will be fully responsive to the Serial port and the System button.

It's now up to you to set up the device. Specifically, you need to:

4. Connect the device to your Wi-Fi router.
5. Obtain the device's local network IP address.
6. Access the device via the Web Interface and perform a thorough setup.

Refer to the linked sections below for detailed assistance. Once the setup is complete, your device will operate as you defined. Check out our other Tutorials and Projects or Blog for inspiration on what you can do with your brand-new unispa device.

Connect to Wi-Fi

Most of the device's setup is done through the Web Interface, which requires the device to be connected to the local wireless network. However, the ESP8266's lack of a keyboard can make this task tricky. Here are several options how to overcome this and connect your ESP8266 to your local wireless network:

1. Access Point option: Generally the most reliable and fastest way to access your unispa device. In this mode, the ESP8266 acts as a Wi-Fi Access Point that you can connect to with your computer or mobile device. Use the built-in setup page to provide the target network's SSID and Password:

   

   Check out our detailed guide for more information.
2. Serial Port option: This method uses a USB cable connection between the ESP8266 and a computer. Using a standard serial console like PuTTY or similar software, send the target network's SSID and Password over the Serial COM port. For example, sending wifissid1 new_ssid and wifipass1 new_password via the PuTTY console will set the new Wi-Fi credentials, which may look somthing like this:

   When using the sensoraya control module or any other ESP8266 module lacking a dedicated on-board USB port, you will need an external USB to UART TTL converter to access it via the serial port.
3. Default network option: The last resort option is to create a separate network with SSID: aya_ssid and Password: aya_pass on an unused Wi-Fi router or mobile device hotspot. The unispa device will automatically recognize this network and connect to it immediately. From within this network, you can access the Web Interface and provide the target network's SSID and Password. This method is not preferred due to potential challenges and roadblocks.

Identify the IP address

After successfully connecting your device to the target wireless network, the next step is to identify its local IP address before accessing it through the Web Interface. There are several options how you may obtain it:

1. Display: The easiest way to identify the device's assigned local IP address is when the device features the Display (e.g. the sensoraya control module) in which case the device itself shows the address on which it can be accesses:

   

2. Access Point option: Besides what is described above, the Access Point mode menu also displays the device's assigned local IP address from the last valid STA connection at the bottom of the Info section:

   

   You can return to the AP mode after connecting to the target network to learn the IP address that will likely remain reserved for the device also for the subsequent reconnection. You can then reboot the device and provide the newly learned address to the Web Interface.
3. Serial Port option: The built-in Serial Interface has a dedicated command wifi info, which when submitted via the Serial COM port, the unispa device responds with basic wireless connection data, including the local IPv4 address:

4. Router option: In case you are an administrator of the target wireless network, the easiest option is to check the client list of your router. You will likely notice the new device named my_unicontrol connected, along with its assigned IP address:

   

Web Interface

Once you have connected your device to the wireless network and obtained its assigned IP address, you can access it via the Web Interface. To do this, you have, again, multiple options:

1. Local interface: Unpack the interface_[VERSION] folder from the downloaded archive and open the index.htm (or any other .htm) file inside. This will launch a locally hosted copy of the original HTML-based Web Interface, with an IP address field in the upper-right corner of the page.

   

   For a better convenience it is possible to host this folder on any webserver present within the local network.
2. Android app: The same HTML-based Web Interface can be opened as an android app available on Google Play. In the app, the IP address field is located in the CONN container.

   

Enter the identified IP address into the highlighted field and click Connect:

If the Connection panel is filled with your device's details and a green dot appears next to its IP address, the interface has successfully established a connection with your unispa device. You now have full control over it and can proceed to create your First pocess.
