Customizing a POP Kiosk
Overview
The POP Kiosk comes with default settings that make it suitable for use as an embedded kiosk, but many of these settings are fully customizable. You can easily change the default resolution, display output, control wireless radios or change the boot logo.
Configuring the Raspberry Pi at Boot
The Raspberry Pi computer uses the boot partition to configure the computer system at each boot[1] . You can edit these files by inserting the kiosk's SD card into a Windows or Mac computer and navigating to the boot drive that is automatically mounted.
Enabling Bluetooth
Open the /boot/config.txt text file in a text editor and search for the line dtoverlay=disable-bt. Add a hash mark # to the beginning of the line so it reads #dtoverlay=disable-bt. Save the file and insert the SD card back into the Raspberry Pi.
Enabling Wi-Fi
Open the /boot/config.txt text file in a text editor and search for the line dtoverlay=disable-wifi . Add a hash mark # to the beginning of the line so it reads #dtoverlay=disable-wifi. Save the file and insert the SD card back into the Raspberry Pi.
Connecting to a Wireless Network
Open the /boot/wpa_supplicant.conf file in a text editor. If it doesn't exist, create a new text file in the boot directory named wpa_supplicant.conf. It is common for Operating Systems to hide file extension, so you many need to verify this file is named wpa_supplicant.conf and not wpa_supplicant.conf.txt. This file needs to be formatted very specifically, according to Raspberry Pi specifications.
country=US # Your 2-digit country code
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
network={
ssid="YOUR_NETWORK_NAME"
psk="YOUR_PASSWORD"
key_mgmt=WPA-PSK
}Changing the Boot Logo
You can easily change the boot logo that is displayed while the kiosk is starting by replacing the /boot/splash.png image file. The file you replace it with must be a PNG file with the name splash.png.
