@codeadamca First of all you can also start python 3 with
python3 your-python-script.py. Now to the requests package: You could install it via the Debian package management: sudo apt-get install python-requests for python 2 or sudo apt-get install python3-requests for python 3.
@countsudoku Thanks! That worked for installing requests for Python3 and I can run requests using the terminal. However, when I use the EV3 Visual Studio Plugin, I get the error "ImportError: no module named 'requests'". I believe this is because the EV3 VSCode plugin uses micropython. Is there a way to install the requests package to micropython?
If you use micropython, you should use
urequestsa micropythen implementation of a subset of the requests funcionality. But I guess that's not the problem here. I don't use VSCode myself, but the problen might be, that requests is not installed in the environment VSCode uses.
So maybe you have to install the
requests package localy. But I am not sure if te EV3 plugin brings it own virtual environment. In this case you have to install the library in this environment.
I have a question for the hardware experts here: I accidentally broke the ribbon cable that connects the display in the EV3 to the main board, and I couldn't find a replacement online, neither for the cable alone, nor for cable+display. So I was wondering whether I could use the EV3 from my laptop without relying on the display. Like, can I ssh into the OS via a USB connection? Connecting via WiFi might be a bit tricky without the display, right? Any hints welcome! Thanks! PS: Sorry if this is slightly offtopic, but I thought this was the forum discussing topics closest to what I'm needing

But if you only want to set WiFi config, which is the 'wpa_supplicant' configuration (add it under '/etc/wpa_supplicant'), you can do it by mounting the SD card on another Linux machine. I am not completely sure if this work, because the brickman WiFi setup does not store the config there. Maybe you have to disable 'brickman' and activate 'wpa_supplicant' service explicitly.
There is also this option: https://www.ev3dev.org/news/2015/07/24/Color-LCD-on-the-EV3/
Hello. I have problems to find a working wifi dongle. I saw the github page with the dongles, but i run into issues, that the version of the chip is not correct, seller couldn't tell my which chip and which chip version it is. Can someone recommend me a wifi dongle, which is working with the ev3dev and where i could buy it? Best case Europe/Germany.
https://www.conrad.nl/p/edimax-ew-7611ulb-wifi-stick-usb-20-wifi-bluetooth-150-mbits-1491083 Be sure not to buy the V2 version. This store (Netherlands) seems to have both. I think this is the right one, but do check it.
Do i have to do some extra steps to get it running except put the usb inside?
If your USB VID:PID doesn't match that one, you will need to research which driver might support your dongle and replace the VID:PID and

Which one are you using?

Hey, hello. I am looking for an example how to use a touchsensor as an toggle switch in ev3dev python. Can anyone give advice?
Hello! I meet some difficulties in using mindsensor RFID reader for ev3(see http://www.mindsensors.com/ev3-and-nxt/213-rfid-tag-reader-for-nxt-and-ev3-with-tag-kit?search_query=rfid+ev3&results=1). I want to use python3 instead of micropython to drive this rfid reader, but only micropython code is provided in the official website. Could any one help me?
@KWSmit Thanks for your suggestions. I decided to change my code to pybricks-micropython so that I can use the mindsensor RFID easily. However, I meet another troublesome problem, that is about umqtt.robust. I used the same code as https://github.com/JorgePe/ev3-mqtt-micropython/blob/master/main.py, and it cannot work. The return error is OSError:[addrinfo error -8], and I don't know why. The mqtt broker I used is mosquitto broker 2.0.11.
Hi folks, I'm trying now for 2 days getting lms2012-compat up and running on my EV3. I tried different things first with the newest R3 Release, now I'm on a fresh R2 Release, but still the same error: "Unsupported Platform" after entering
sudo FK_MACHINE="LEGO MINDSTORMS EV3 + lms2012-compat" flash-kernel. I also checked that cat /proc/device-tree/model; echo and the line Machine in db.all match. My lms2012-compat version is 1.99.7. On this Release i did the sudo apt get update && apt get install lms2012-compat now I'll try also the sudo apt get upgrade but I'm not confident that this is it. I would really appreciate any help as I need lms2012 getting to work. Because I want a connection to Matlab for my university project. Alternatives for connecting Matlab with EV3 and Third-Party Equip (motor multiplexer and wifi-dongle in this case) are also very welcome :D

update: while upgrading with sudo apt get upgrade there was a proplem with the initramfs-tools package (once again, had this also in previous try with the R3-release) and it exited with 1 error.
So I did it again and it showed me:
update-initramfs: Generating /boot/initrd.img-4.14.117-ev3dev-2.3.5-ev3
I: The initramfs will attempt to resume from /dev/zram0

Now no more errors and everything upgraded. But still "Unsupported Platform." :(
