0x5344 from the oemid means SD as in SanDisk. Type is probably not easy; I guess it is their internal name. Read more at https://www.cameramemoryspeed.com/sd-memory-card-faq/reading-sd-card-cid-serial-psn-internal-numbers/

is there a way to set the raspberry automatically wake on after a power failure (such as a black out)? Since there is no power button this will happen automatically. When you plug a Pi in, it turns on, so the same thing will happen when the power comes back. Beware that cutting the power arbitrarily (such as in a black out) risks filesystem corruption.1 ...

Yes, it's called VNC Viewer, and you'll find it in the "Recommended Software" app (under Preferences in the Raspbian desktop menu). Or, if you prefer the command line, you can do "sudo apt install realvnc-vnc-viewer".

I had the same exact problem, after searching through I found that problem was related to authentication and following line helped me to resolve the issue. I forgot which Stack Exchange I found the answer from. Here are the steps that I took: Connect to your Raspberry Pi through ssh command. ssh pi@your raspberry ip Then enter your password to your ...

This is not a Pi problem. Devices used as hotspots generally DO NOT allow through connections. Similar issues arise using Internet Connection Sharing on a PC.

Reading the comments to @joan's answer, it occurs to me that you might be open to "Low Power" in lieu of "Zero Power". If that's the case, and your RPi model is 4B you can reduce the current draw to about 35-40 mA (200mW) by changing a couple of configuration variables in your EEPROM bootcode. See this answer for details. You can schedule ...

You can't use a script running on the Pi to switch the Pi on when off. I leave it to you to work out why a script will not work if the Pi is not powered. You need an external device to switch the power on. Why do you need to switch the power on and off? You could use a script to reboot the Pi.

As per microsoft implementation you can take only one RDP session at a time. If you want to use more than one RDP session then you need to check the Terminal Service under Windows Server where it requires configuring an Windows Server with CAL license which will cost you too much. There are other ways to achieve this using RDP Wrapper but by taking that ...

Raspbian is using a thing called mDNS, which allows you to access your raspberry pi by a hostname raspberrypi.local. So, you don't need to search for an IP address anymore, just connect like so: ssh pi@raspberrypi.local

Try this first: arp -a | grep -E --ignore-case 'b8:27:eb|dc:a6:32' The two hex strings (b8:27:eb|dc:a6:32) in this command reflect the two OUI values used by "The Foundation" for production of all RPi devices - through RPi ver 4B as of this writing. If your RPi isn't in your arp cache this command won't yield anything useful. If that's the case, ...

You can create a RealVNC account. By the time you do that, the Raspberry Pi will get in your address book. Security Be careful! If you just forward the port on which your VNC server works on, your data could be exposed to hackers. You must use the SSL/TLS protocol to ensure secure communication and a DNS.

Though this is an old post, I hope I can help someone else that is looking for a simple solution. I found this platform a while ago - https://www.upswift.io I use their Remote Access feature in order to connect to my rpi4 using VNC. I basically followed this guide: https://www.upswift.io/post/remote-access-to-your-linux-iot-device-through-vnc?utm_source=...

Sydney regularly tops 40C in summer, and Pi works without problems. Whether you need heatsinks/fan depends on model and application. It would obviously be prudent NOT to leave the Pi in direct sunlight. Personally I would be more concerned about humidity.

EDIT: This only seemed to fix the problem temporarily! FOUND THE SOLUTION! It seems it was an issue with the router. My DHCP IP range was set to be 10.0.1.100-10.0.1.200. This seemed to cause an issue with how the router handled the traffic between devices and would drop connections. I set the DHCP range to 10.0.1.2-10.0.1.202 and it seems to work fine now....

It's not an error message, it's a directory index. "Index of /" means "this is the index of the root directory". And "Name Size Date Modified" are the column headers. But vsftp is unable to list any files. I suspect you have a permissions or file corruption problem.

I found my error. I was scanning for wrong ip address range in the 'advanced ip scanner'. Thank you @Andyroo , i found my answer in your reply. I'm a beginner in this, so that's why I couldn't figure out such a minute problem.

I assume that you are trying to connect to an iPhone (which you should mention). If so the character is NOT an apostrophe - it is another Unicode character. If you search my answers in this Forum you will find a suggestion, but it is far easier to change the iPhone to a sensible SSID.

What probably happens is, that your directory libs gets chmodded first. Chmodding recursively always requires a bit of attention. To have access to a directory, it must be executable for you. 0644 means that the directory is not executable, and therefore not accessible. Instead of your recursive chmod try the following: find libs -type d -exec chmod 0755 {} \...

It's been a year since the last reply, but just to add -- there's also a hardware way of doing this. There are small devices which plug into a HDMI-port and emulate a monitor. If you use such a device on a Pi, the Pi will think there's an actual monitor connected. The ones I've seen are normal sized HDMI connectors, but I'm sure there will be micro-HDMI ones ...

The Raspberry Pi 4 has OTG capabilities on its USB-C Port. You can free that up by powering the board using the GPIO pins. Since the Pi already has a camera input, you probably get a better picture with something inputting video to the camera head. There are several boards on Ali express that do that (search HDMI to CSI-2, if you really need VGA, you could ...
