Starting hostapd when WiFi goes down #piday #raspberrypi @Raspberry_Pi
This is an interesting solution to wifi on a headless computer – when no wifi access point is found, automagically flip over to becoming an access point so it’s still accessible locally! From http://sirlagz.net/:
I’ve had issues with my WiFi in the past, and with my Pi running headless it’s sometimes a pain to get it connected back up to WiFi, so I’ve created this little script to start hostapd and dnsmasq whenever the WiFi connection went down, which allowed me to SSH into the Pi even though it wasn’t connected to the network, because it was broadcasting it’s own network !

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
