As soon as the assembly is completed, your device can be put into operation. The device's battery is already pre-charged upon delivery. However, to ensure maximum runtime, the battery should be recharged via the micro USB port on the motherboard, which can be accessed via the back of the device. A full charge can take up to 5 hours.
|ⓘ Important Note|
|The device does not have a battery charge indicator. When the battery is low, the images are only built up incompletely. You should charge the battery at the latest then.|
Some images are already pre-installed at delivery. The time between automatic image changes is configurable and factory set to one hour. Most of the time your ArtFrame will spend in sleep mode to save the battery. Then the status LED is off. If it is on, the device is active.
If you now press the LED button briefly, the status LED will start to light up. After a few seconds, the image will change, after which the status LED will go out.
If, on the other hand, you press the LED button for longer than four seconds, the configuration mode starts instead, which is explained in the following chapter. If you now press the LED button a second time, the configuration mode is ended and a new image is displayed. The device now switches to the idle state and the status LED goes out.
To adjust the settings of your device, press and hold the LED button on the bottom of the device for approx. 4 seconds. The status LED immediately starts to light up and the words CONFIGURATION MODE appear on the display. Follow the instructions on the display.
If you are doing the configuration for the first time, a WiFi hotspot with the name ArtFrame will now be created. Connect your smartphone or laptop to this WiFi and then open the URL http://192.168.1.1 in the web browser.
|ⓘ Important note|
|On some Android devices, opening the URL only works when the mobile data connection is turned off.|
If you have already stored WiFi and Password in the settings, the device will first try to log into that WiFi and provide the configuration interface there. This way you can configure the device via your home network. The URL to be opened in the browser is different then. However, if the connection attempt fails, the WiFi hotspot described at the beginning is created instead.
|ⓘ Important Note|
|The device has an increased power requirement during configuration mode. To achieve the maximum runtime, you can charge the device via the micro USB port on the back after configuration.|
The behavior of your ArtFrame can be customized via the configuration interface. In addition, the version of the currently installed software is displayed in the lower right corner. The various settings are explained below.
This switch can be used to select between Local and Remote mode. Depending on the selection, various specific settings are visible.
In Local mode, the ArtFrame will display images from the local memory of the device.
In Remote mode, the images are loaded and displayed via the WiFi.
|ⓘ Important note|
|In Remote mode, image switching takes a bit more time than in Local mode. Thus, the battery life is slightly reduced in this mode.|
These settings are only relevant for the Local mode. Here you can manage the images stored on your ArtFrame. A status bar indicates the used storage space. Below there is a list of the images stored on your ArtFrame. An image can be deleted using the Trash icon. Using the Upload Files ... button, images can be selected and transferred to the ArtFrame. For each selected image a preview is displayed where contrast and brightness can be adjusted. A dashed line indicates the image section to be transferred. It can be moved and resized.
The adjustments are confirmed with the OK button. The image is now processed and transferred.
General settings can be changed here. Some of them are only relevant in Remote mode.
If your ArtFrame is to be operated in Remote mode, the WiFi via which the connection is to be established can be entered here. The WiFi must transmit via the 2.4 GHz band. 5 GHz is not supported.
|If this setting is not empty, your ArtFrame will first try to dial into the stored WiFi when starting the configuration mode. This way you can directly access the configuration interface within this WiFi. If the connection fails, a separate WiFi hotspot with the name ArtFrame will be started instead.|
If the WiFi to which your ArtFrame is to connect is password protected, the password must be entered here so that the connection can be established.
If your ArtFrame is to be operated in Remote mode, the URL from which the images are to be obtained can be entered here. For testing the URL http://framelabs.eu:8090/ is preset.
|The URL must consist of protocol, domain name, optional port, and a path. The path must not be empty. Therefore, in the example above, the / at the end must not be omitted.|
How to start up a self-hosted Image Server is described in the following chapter.
This setting determines how much time should elapse between image changes. The time interval can be set to the minute. We recommend an interval of one hour.
|The longer the interval, the longer the battery will last until it needs to be recharged.|
When you press this button, the settings are saved. The device exits the configuration mode, performs a picture change and enters sleep mode.
Your ArtFrame has the ability to download and display images over WiFi.
The software image_server.py is a Python program that serves images via an HTTP interface. For each request a random image is selected.
To display the images on your ArtFrame, it must be set to Remote mode, WiFi and Password must be entered correctly and the Image Server URL must be set to http://[IP address of server]:8090/.
The .rawz image format is a zlib-compressed framebuffer with 4 bit per pixel, starting line by line from the top left. Every byte contains two pixels, with the left pixel as the less significant bits. A sample implementation showcasing the conversion from and to the format can be found at https://github.com/framelabs-eu/tools.
Connect the micro USB port on the back of the device to a USB charger using the USB to micro USB cable. A full charge can take up to five hours. A red LED indicates the ongoing charging process. It is visible through the display and goes out as soon as charging is completed.

|The e-paper display retains its content even without power. In the event of an error, always check whether the status LED is lit first. Only then are any instructions on the display also up-to-date.|
Error messages that appear on the display or the configuration interface are usually external errors.
|Could not connect to WiFi||The device is running in Remote mode but cannot connect to the configured WiFi. Check the saved WiFi and Password and make sure that the WiFi is reachable on the 2.4 GHz band. If this does not remedy the situation, reduce the distance to the WiFi router.|
|Couldn't connect to server||The device is running in Remote mode but cannot receive data. Check the saved Image Server URL.|
|No pictures installed||The device is running in Local mode, but there are no images installed. First load images onto the device.|
|Error: Not enough space||The local storage of your ArtFrame is full. If you want to transfer more images to the device, you must first delete other images from its local storage.|
If unexpected behavior occurs during operation, but no error message appears, it is often an error that is caused by the battery level being too low. The following error pattern is typical for this: The new image could no longer be built up completely. In such a case, the battery should definitely be fully recharged.
Further problems and possible solutions are listed below.
|The configuration interface cannot be reached.||Check whether the status LED is lit. If this is not the case, the battery must be charged.|
|Check if your smartphone or laptop is connected to the WiFi that is mentioned on the display.|
|If you are using an Android smartphone, disconnect the mobile data connection and then try again.|
|Try to establish a connection with another device.|
|Check whether the ArtFrame reacts when you press the LED button briefly.|
|An image cannot be uploaded.||With very large images in connection with old smartphones, the phone can be overwhelmed when processing. Try again with a different browser, smaller image or with a smartphone with more RAM.|
|Images show artifacts, look incomplete, or are not fully displayed.||Charge the battery.|
|The status LED does not light up after the LED button has been pressed.||Charge the battery.|
|The status LED flashes once when you press the LED button and then goes out.||There is an error with the communication to the display driver board. Charge the battery. If this does not solve the problem, check the cabling.|
