问题 I am having problems trying to display the RSSI values from my raspberry pi 3 to show on my server. Connection Success as you can see by the picture I have been able to successfully connect my client and server but no rssi data are showing. The following code is what I executed from the pi: var noble = require('noble'); //replace localhost with your server's IP; var socket = require('socket.io-client')('http://localhost:3000/scanner'); //replace with your hardware address var addressToTrack =

问题 I'm trying to setup a MACVLAN for my docker containers. I have a fresh Raspbian and Docker installation and followed the steps outlined to the Docker Documentation to create a MACVLAN: https://docs.docker.com/network/network-tutorial-macvlan.

问题 I am building a stand-alone VR headset using Raspberry Pi 3 model b. I am having a problem with splitting the screen as we see on our phone. I am still learning Python so I don't have much idea on how to do this. Here in this code, I have tried to solve the above-mentioned problem but when I run this code on Raspbian an error occurs that ImageGrab function works only on Windows and Mac. I tried to use pyscreenshot module also, although it works on my PC screen fairly when I connect it with my

问题 I am able to build my javafx11 application, but I get errors when running it using ./gradlew run The error I get says something about unable to open DISPLAY I have tried on both a terminal only install of raspbian and a full desktop install as well. So far I have done these things: 1) Install bellsoft full jdk 2) git clone gradle project 3) ./gradlew run What am I doing wrong? 回答1: Nevermind, I figured it out after much, much more googling. I ended up using nodm . 来源： https://stackoverflow

问题 I want to monitor air quality inside my flat (downstairs neighbor is an avid smoker). For so doing, I have a Raspberry Pie 3 Model B+ connected with an Enviro+. While in the terminal I can run the script that measures small particles. python particulates.py cf. https://github.com/pimoroni/enviroplus-python/blob/master/examples/particulates.py It then runs and display the data in the terminal, like in the picture below: (yes, I am better at lego-ing, than coding). I am interested in keeping a
