Re: USB Wi-Fi card on Raspberry Pi 2 doesn't work even with drivers installed

Reinstalling the OS and repeating the process does not work.

Re: USB Wi-Fi card on Raspberry Pi 2 doesn't work even with drivers installed

This reply was delayed because I had a huge spike in homework load and I took the SAT on the weekend. Unplugging and replugging my wi-fi card after booting my pi does not work. Unplugging everything for a while and trying again does not work. Having country=US does not work. rfkill unblock wlan does...

Re: USB Wi-Fi card on Raspberry Pi 2 doesn't work even with drivers installed

The only part I was missing from the sample file you provided was the country code, and adding that did not fix the issue. I thought it was only required on the 3B+. Is that not correct? I tried blacklisting r8188eu by adding the line "blacklist r8188eu" to /etc/modprobe.d/8188eu.conf.According to e...

USB Wi-Fi card on Raspberry Pi 2 doesn't work even with drivers installed

I originally tried at https://www.raspberrypi.org/forums/viewtopic.php?f=28&t=257352 to get my wi-fi working, but the instructions provided didn't help and I got ghosted.

Re: Cannot connect to wi-fi

I managed to follow some tutorials. Mr. Engman had an install script somewhere. The only difference it makes is that now the LED on my card flashes slowly all the time, when it used to only flash when scanning. I still cannot connect, and it still throws nonexistent device errors. Blacklisting r8188...

Re: Cannot connect to wi-fi

Sorry for late reply, I just had a chance to look at this now. I don't quite understand what I'm supposed to do there. I found the git repo at https://github.com/Hexxeh/rpi-firmware/tree/master and the relevant files within that repo. How do I install a ko file?

Cannot connect to wi-fi

I have a raspberry pi 2 running Raspbian Buster that I need to connect to wi-fi using a wi-fi dongle based on an RTL8188EU chip. I read that this chip is supposed to be supported out of the box in the newer versions of Raspbian, so I have not installed anything. The setup screen that appears on firs...

Re: Asynchronously send email in python?

1. That's good. I'll prioritize the threading, but I'll make sure to add ctrl+C handling at some point. 2. I've got a 3B+. I feel like running the CPU at full power will consume a few extra cents of electricity per year. I'm not the one paying the electric bill here, but I don't want to get addicted...

Re: Asynchronously send email in python?

Thanks for the link to the topic. That looks like almost exactly what I want. If I understand correctly, this will allow the main thread to continue with its monitoring and executing while the secondary thread will handle the emails, right? If both threads are doing processing, then it switches betw...

[SOLVED] Asynchronously send email in python?

I have my raspberry pi monitoring something that may change fairly frequently. I want it to send me an email when that happens. I already have it working almost perfectly, except emails the monitoring gets blocked for 15 seconds to a minute when the email is being sent. If something happens while th...

Re: fun idea pi4 as a gpu?

I would think it would be possible, but it might be difficult to do if software that does that doesn't already exist. You would also need to find a way to get the pi to act as a USB slave rather than a USB host.

Re: Can I connect an arduino directly to GPIO using a 10k ohm resistor?

I'm going to keep the 1k ohm because with just the 4.7k, it will be 3.4V. I read somewhere that the GPIOs can tolerate 4V, but I'm not going to take the chance. The Pi is cheap, but not cheap enough that I would consider it expendable. I read that the activation threshold is 1.8V, so I'd rather have...

Re: Can I connect an arduino directly to GPIO using a 10k ohm resistor?

It's an Uno, and I know for sure it is 5V. The existing code checks an ultrasonic sensor and turns on a pin based on the values. I'm limited to the resistors I have under my bed. Can I use 4.7k (yellow-purple-red) + 1k (brown-black-red) for a total of 5.7k as my "first resistor" and 10k (brown-black...

[SOLVED] Can I connect an arduino directly to GPIO using a 10k ohm resistor?

I know this is going to be very hacky. I'll make a proper solution later. I need to build something with my raspberry pi on short notice, and I determined that it would be less time consuming to interface my Arduino running some of my pre-existing code with my Pi than it would be to port the circuit...

Re: Cannot connect to Wi-Fi

I have hundreds of gigabytes of data from using my pi as a server, so migrating it will be a big hassle. I can migrate to a new image if it is really necessary, but I don't want to.

Cannot connect to Wi-Fi

I have a 3B+ and I'm in the process of upgrading to Buster. I just lost my wi-fi connection, and I am unable to reconnect. Clicking the normal wi-fi icon tells me that there are no interfaces, which obviously isn't true because wi-fi is built in. A new icon appeared in the taskbar that looks like tw...
