Problem solved! It seems that even though I added the gateway information into the interfaces file, wlan0 didn't really have a default gateway.

No, the Pi Zero does not support ethernet over HDMI.
Unfortunately the schematics for the Pi Zero are not available (edited: an overview schematics is available now, see updated information below). However since it is essentially an minimized Pi 1 I'd bet that the HDMI circuitry is (nearly) the same - though the Pi 1 features a standard sized HDMI connector ...
This applies to Raspbian Wheezy prior to 2015-05-05 for later (and Jessie/Stretch) See How do I set up networking/WiFi/Static IP
As suggested by the community, my answer extracted from the question.
I got it working right now so I'll share all my configuration files with the community. Firstly lets look at the wpa_supplicant.conf file:
pi@raspberrypi ~ $ ...
This feature is called CEC. It allows a device to be controlled with a remote from a TV through the HDMI cable. You can even switch on/off automatically a device when you switch on/off your TV.
It works out of the box with many devices such as PlayStation 3, A/V receivers, and Raspberry Pi as well (from my exprience, only with the OpenELEC distribution, but ...
HOW TO REPLACE SSH HOST KEYS ON RASPBIAN W/O BOOTING INTO IT
Note: I had this happen with a recent download and install of Raspian full... it occurred on a headless pi zero W and a headless pi 3B+. This solved it in both cases. Not sure what was wrong with the keys but I suspect something may have been broken in the distribution.
If your ssh "connection ...
If a device does not have internet access or other access outside the local subnet, then you should eliminate the gateway. Listing a gateway on both interfaces is likely the culprit.
If the ethernet is for the local subnet only remove that gateway.
The way I initially connected was with a USB serial dongle at the PC end connected to the Pi's UART and ground.
You can then use terminal emulator software to log in to the Pi. You then have the old fashioned 80x25 text window to enter commands etc.
I think Windows users tend to use a tool called putty for the emulator (there was a tool called ...
You don't mention which OS you are using, but there area couple of ways to do this:
You can try ssh pi@raspberrypi or ssh raspberrypi.local (this will may need to be adjusted if not using Raspbian - the first part is the username (pi) the second is the host name).
You can login to your router and check the device list.
You can ping the entire subnet using ...
From a programming perspective, messages on networks are transferred via sockets. There are two predominant forms of networking, connection (aka. stream) based and connectionless (aka. packet) based. The latter uses the UDP protocol and the former the TCP protocol. TCP connections are established between servers and clients; some applications maybe ...
You could try executing the following through the command prompt:
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
wait for reboot
sudo branch=next rpi-update
wait for reboot
This should grab the latest firmware and updates to make your Pi be able to successfully find networks and connect to them....
A USB OTG connection seems like the best option here. It will be much faster than about any alternative (certainly faster than I2C or UART), and with the g_ether driver you will be able to use it as a regular network, so your videos can be either streamed or saved as files and transmitted using HTTP, FTP, netcat etc.
You will need a micro USB cable and a ...
By far the easiest options for moving large amounts of data between Pi Zeros and other Pis are USB OTG, which has already been covered by Dmitry Grigoryev's answer, and ethernet or WiFi.
While USB OTG will work great if your Pis are fairly close together, the run length specification for USB tops out at around about 5 metres. Further apart than that and ...
NO. That setup won't work. The GPIO pins are not suitable to drive equipment directly, due to the fact that:
They can only provide a very limited current (up to 50mA, although this might be higher on the rPi2)
They have no protection against flyback currents etc., so driving a load with a motor or relay in it will possibly kill your rPi
You will need the ...
SSH is a good way to access the command prompt over a network, via ethernet or wifi. VNC is a good way to access the desktop of your pi over a network. https://www.raspberrypi.org/documentation/remote-access/ssh/
The manual on the Trancend Website (see pjc50's answer) suggests that the unit will be recognised by a PC if a USB lead is connected to the mini-USB connector (C) on the SIDE of the case (not the full size one on the back). It says that a Linux kernel 2.4 or greater is required then any memory card inserted in the unit will appear for the PC to access (and ...
I solved the problem.
First I updated my settings as suggested in the link that Miliways provided in a comment in my original answer.
That alone didn't solve it, what I actually had to do is change the configurations in my router:
The WiFi was set to WPA2/WPA -> I changed that to WPA2 only and now I can finally connect to the network without problems.
You could also try and ping 220.127.116.11 to see if you are actually able to get packets out to the internet. If you are then check your DNS settings as per
You would expect to see something like
Check that the DNS server in there is actually live and working. If not, edit it using something like nano, then see if it ...
The RPi and the PC need to be in the same logical network, which they are not.
The computer is in the 192.168.225.0/24 network, and the Pi is in the 192.168.137.0/24 network.
You need to change the IP address of the Pi to be in 192.168.225.0/24 (example: 192.168.225.10 with subnet mask 255.255.255.0).
I had this exact problem, down to every detail stated in the original question. Upon additional searching, I saw this question (with the same wording) was cross-posted in the raspberrypi.org forums where a user suggested this solution:
The poster of the ...
I have read through this post, I don't know how many times, but just today I noticed:
iface eth0 inet static
I know this is an old, "fixed" issue, but did you maybe correct the spelling of "autho eth0" along the way, one day? It's good to get things working, but better to know how you ...
Usually these types of WAP's use something called Captive Portal, which intercepts http traffic on port 80, then redirects it to their login page until the user is logged in.
Try getting the terminal web browser package links and browsing to a website using a http (not https) and it should redirect you and allow you to log in.
It has exactly the same programming interface as the HC-SR04.
You send a trigger pulse of 10µs or more on the trigger line.
Shortly after the trigger line goes low the echo line will go high. The echo line will stay high until the echo has returned (or the echo times out). The echo line high time is the time the sound took to travel to the detected ...
The AM7338 is a dedicated Digital Picture Frame System on Chip (DFP SOC). It is a all in one single chip solution for DFPs, handling typical functions of buttons, IR remote, memory card and flash reading, USB host and slave, and most important, direct LVDS display interfacing.
It is in the same family as other AM733x chips, and they all use the same general ...
Does your motor driver support controlling 2 motors?
Have you thought about talking to your motor driver(from the Pi)?
keep in mind the Bluetooth does use up the Pi's UART! (see comments for more information)
For quick wiring, those are great, either many of them, or in bulk like the one I just found(you could also tear them apart when needed)
For solid ...
The Raspberry Pi DSI (Digital Serial Interface) connection. The problem is that not all LCD/TFT screens use the same implementation. DSI is a simple interface but the LCD/TFT controller needs to work with that protocol.
The Raspberry Pi DPI (Parallel Display Interface) is another way to communicate with RGB type displays and can be configured as documented ...
The obvious way is to use the Pi's Ethernet port and network them with a switch or router.
Using the GPIO will be far more complicated and much slower.
This question has nothing to do with the Pi in the way you have asked. It is a general network question.
"Houston, we have a problem"...
Just as an aside, and before I try to provide some answers, I should tell you I am really NOT very keen on troubleshooting project designs and blog posts that people drag into this forum. I think @joan's comment above reflects a similar sentiment. Why do I say this - why do I feel this way? I feel that if you're following a ...
This is not a question belonging to Raspberry Pi. It is a problem with MS Windows. But because it is an often seen problem together with Raspberry Pi I will give a hint.
Raspbian uses a Link-local address if there is no DHCP server present. For these addresses there is a top level DNS domain .local reserved so you can address link-local addresses with this ...
I borrowed the RPI 3B from a friend's friend. hence I don't know the
hostname so that I can ping the RPI to know its IP address.
Raspberry Pi is a board without any internal storage hence it doesn't matter where you got this. You installed your own operating system (a downloaded image file) on the SD-Card and because of that, you have formated (remove any ...
The setup should not be a big problem because there are no routing requirements. The wired subnet is isolated from the wireless subnet. So you can just connect wireless to the internet router with wpa_supplicant as usual. The wired connections should work out of the box when only using static ip addresses and no name resolution. To be more comfortable you ...
