I've found the issue. In the example they tell you to use raspi-config to disable the OS from using the serial port. This is done via this guide: https://www.cube-controls.com/2015/11/02/disable-serial-port-terminal-output-on-raspbian/ What happens when I use disable the serial port via raspi-config...

I'm having trouble using Pi4J at the moment. I've copied their example and changed it a bit. I've connected my pin8 and pin10 with eachother, since these are the UART pins. I've written code that writes some string to the serial and then reads it. However I am getting an error: Unable to connect to ...

Great! Thanks again You really helped a lot!

Great thanks for the help so far! If I do connect the rx and the tx pins, should I put a resistor in between the two pins? I am quite a noob on the electrical engineering part...

Thanks a lot! Is it possible to debug my serial code by simply connecting the Tx and the Rx of the Pi. This way the Pi will send data over it's Tx and this data will be looped back to the Rx, making it echo what it send. Am I right?

Hello there, Currently I'm working on a personal project. This project contains a Raspberry Pi and a RN2483. The RN2483 has a ASCII command interface over UART. So in order to use the RN2483 chip connected to my Pi, I'll have to use UART... Can I use Pi4J and its Serial example to start off implemen...

For some reason the problem solved itself. For the first time in like 2 years I've gotten a new IP from my ISP. And since I got that new IP the ssh works from all systems I use/own. I haven't changed anything in my ssh settings on both my client and server. I think it had something to do with my ISP...

It doesn't just only not work on my university's network. It doesn't work from anywhere...

I know about that issue! I already put my sshd on another port. I also disabled the functionality to login as root, so no harm could be done. When I tail -f my /var/log/auth.log I dont see as many login attempts anymore as when sshd was on port 22. This still doesn't fix the problem tho. Still thank...

Hey there, I just installed Raspbian on my Raspberry Pi and really want to get SSH working. I already forwarded port 22 in my router and gave the pi a static IP. Whenever I SSH the pi via its local IP on either Windows or Linux I get a connection and I can start using SSH. The problems start at usin...
