Enabling Simultaneous AP and Managed Mode WiFi on Raspberry Pi Zero W
Personal note: Running both an access point and a client configuration on the same network adapter (i.e., simultaneous Client/AP mode) requires support for so-called virtual interfaces. Whether a certain Wifi hardware and driver combo supports virtual interfaces and in which configurations can be found out by looking at iw list output (look for AP and … Continue reading Enabling Simultaneous AP and Managed Mode WiFi on Raspberry Pi Zero W
Raspberry Pi Serial Connection
Source: https://elinux.org/RPi_Serial_Connection The serial port is a low-level way to send data between the Raspberry Pi and another computer system. There are two main ways in which it can be used: Connecting to a PC to allow access to the Linux console. This can help to fix problems during boot, or to log in to … Continue reading Raspberry Pi Serial Connection
Set up WiFi through the command line terminal on Raspberry Pi
This method is suitable if you don't have access to the graphical user interface normally used to set up WiFi on the Raspberry Pi. It is particularly suitable for use with a serial console cable if you don't have access to a screen or wired Ethernet network. Note also that no additional software is required; … Continue reading Set up WiFi through the command line terminal on Raspberry Pi
Dynamic Host Configuration Protocol (DHCP) on Raspberry Pi
https://www.raspberrypi.org/learning/networking-lessons/lesson-3/plan/ In this lesson, students will learn how the Raspberry Pi can be used to demonstrate Dynamic Host Configuration Protocol on an isolated network. By now it will be clear that repeatedly changing the /etc/network/interfaces file is time-consuming and laborious. There are a number of disadvantages to giving static IP addresses to all computers on … Continue reading Dynamic Host Configuration Protocol (DHCP) on Raspberry Pi
Configure Raspberry Pi 3 as a WiFi Access Point (AP)
The tutorial below is for Raspberry Pi 3 ONLY. One of my thoughts was, can I use it as a SoftAP for some ESP8266 sensor nodes? As it turns out, you can, and it's not that difficult, as the BCM43438 chip is supported by the open-source brcmfmac driver! Packages The first step is to install … Continue reading Configure Raspberry Pi 3 as a WiFi Access Point (AP)

If you don’t want to check or remember the IP address of Raspberry Pi on LAN
The flexible way: Set up avahi / zeroconf. Zeroconf is 'a set of techniques that automatically creates a usable Internet Protocol (IP) network without manual operator intervention or special configuration servers.'[3]. Avahi is an implementation of zeroconf which 'ships with most Linux and *BSD distributions' [4], but not the Raspberry Pi's Debian distribution. Zeroconf will … Continue reading If you don’t want to check or remember the IP address of Raspberry Pi on LAN
