Headless WiFi Setup for Raspberry Pi : IoT Type Projects

RaspiWiFi: From Guided WiFi configuration software for the Raspberry Pi, Copyright (C) 2015 Jason Burgett jasbur@gmail.com with modifications from Makomo and this release mexmarv@gmail.com.

RaspiWiFi is a program to headlessly configure a Raspberry Pi's WiFi connection using any other WiFi-enabled device (much like the way a Chromecast or similar device can be configured). RaspiWiFi has been tested with the Raspberry Pi B+, Raspberry Pi 3, and Raspberry Pi Zero W.

 

• This version has been updated for use in Raspbian Stretch (as of June 2018 release).
• This version no longer affects /etc/network/interfaces. It now configures via /etc/dhcpcd.conf and runs dnsmasq for DNS server instead of isc-dhcp-server.

INSTALLATION INSTRUCTIONS:

To install:

git clone https://github.com/marvmex/IoT-RaspiWiFi.git
cd IoT-RaspiWiFi
sudo sh start.sh

This script will install all necessary prerequisites, copy configuration files, and reboot. When it finishes booting it should present itself in "Configuration Mode" as a WiFi access point with the SSID pi-IoT.

OBSERVATIONS:

• If you run a non-stock /etc/rc.local, modify rc.local.apclient and rc.local.apclient.template in /usr/share/configure_wifi/Reset_Device/static_files/
• /etc/rc.local will be overwritten everytime the system configured to act as a wifi access point for setting up a new network.
• If you happen to need a non-stock rc.local during the short time when the system is in the "Configure WiFi" configuration, modify rc.local.aphost and rc.local.aphost.template.
• su -c "cd /usr/share/configure_wifi/Configuration_App/ && rails s -b 10.0.0.1 -e production -p 10 -d" & if you need to start the rails web server on IP and port.

USAGE:

• Connect to the pi-IoT SSID Open Access Point using any other WiFi enabled device.
• Navigate to http://10.0.0.1:10 (Port:10 IP:10.0.0.1) using any web browser on the device you connected with. It may take several seconds (or a minute) before the server is ready to accept requests.
• If you're connected to the RasPi via WiFi, it will give you an IP in its network but the web page is timing out (web server still not loaded), then just wait a couple seconds till it appears (patiently)...
• Select the WiFi SSID connection you'd like your Raspberry Pi to connect to from the drop down list and enter its wireless password on the page provided. If no encryption is enabled, leave the password box blank.
• Click the Connect button.
• At this point your Raspberry Pi will reboot and connect to the access point specified.

The files for this process are stored in /usr/share/configure_wifi

RESETTING THE DEVICE:

• If GPIO 4 is pulled high for 10 seconds or more, the Raspberry Pi will reset all settings, reboot, and enter "Configuration Mode" again. It's useful to have a simple button wired on GPIO 4 to reset easily if moving to a new location, or if incorrect connection information is ever entered. Just press and hold for 10 seconds or longer.
• You can also reset the device by running: sudo python3 /usr/share/configure_wifi/Reset_Device/manual-reset.py

Enjoy!
