I am also having this same issue. I have an access point up and working under Jessie and started with that configuration under Stretch. If you have yours working, I could sure use your suggestions. Thanks! Apologies but I eventually gave up as I was gifted a mini hotspot gizmo by a friend that also...

Hi all, I'm trying to set up my Pi Zero W as an access point, as per the official tutorial here: https://www.raspberrypi.org/documentation/configuration/wireless/access-point.md However, I'm having some trouble getting dhcpcd to play nice. After adding the following to /etc/network/interfaces : allo...

Thanks very much for looking into it in such detail!
Much appreciated.

80Hz is a ballpark figure for the frequency at which I need to step the motors on the bot.
The PID loop will be running at ~30Hz since that is the maximum sampling frequency of my accelerometer

Hi all, I need to run a control loop for a robot at 80Hz in Python. Obviously there are various ways to do this using time/datetime etc, starting each loop iteration once dt has elapsed. I have two questions: 1) I have heard that when using time/datetime, the values may not always be accurate at the...

Thanks for your reply. There is no error from Python, the only output I get is that SPI invalid argument error. I'm using this library, which uses Cython to essentially allow use of the Arduino RF24 library. Cheers, your approach might likely be the way I end up going, but I'd like to see if there's...

Hi all I'm using the PyRF24 library to try and use an nRF24L01+ radio module with my Pi. When I run this code: from pyRF24 import pyRF24 radio = pyRF24("/dev/spidev0.0", 8000000, 18, retries = (15, 15), channel = 76, dynamicPayloads = True, autoAck = True) I get the following error: can't send spi m...

This is what /etc/resolv.conf contains: domain home search home nameserver 192.168.1.254 Also wifi doesn't connect on boot, I have to connect it to ethernet, ssh it then manually bring the wifi up. It then doesn't stay on for more than a few minutes. I also now cannot ssh it over ethernet using mypi...

Thanks Mr Engman :) I added that line and it now works fine, I can ssh it from other devices in the network. However, when I try to ping google.com I get Connect: Network is unreachable This puzzled me so I tried it with ethernet and got the following ING google.com (173.194.34.68) 56(84) bytes of d...

Someone else having wifi problems - using Edimax EW-7811UN. I've trawled through various solutions but have had no luck so would appreciate some help :) cat /etc/network/interfaces auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.1.50 gateway 192.168.1.1 netmask 255.25...

Update:
I can now launch the GUI by doing
xinit /usr/bin/lxsession
But still no luck with startx.
The message that I get after running startx is the same one I get if I close the GUI.

Hi all I've been running my Pi headless for quite a few months now, and a few days ago I decided to plug in a monitor, mouse and keyboard, partly because I wanted to have a play with the Arduino IDE. Anyway. Booted to user credential entry, I logged in as pi, which is the user I use. Ran "startx". T...

Hi all I'm looking to buy a wireless keyboard and mouse that both transmit to one USB dongle which plugs into the Pi. I was wondering whether anyone has any experiences of these and any thoughts on which are the best models. My only requirements are that it's a real mouse not a trackpad, and that bo...

Hi there :) I've been using this tutorial to get my dht-11 temperature sensor working: http://blogs.sequoiainc.com/blogs/raspberry-pi-home-brew-temperature-monitor The attached file shows the output. As you can see, most of the outputs don't work, and when it does, sometimes it gives random readings...

Hi there. I'm a fair beginner to the Pi, and have a question for the pi gods :) The one thing that I find tedious when using the shell is doing "ls" after every time I do "cd". (I'm lazy) Just wondering, how easy would it be to create a function combining cd and ls, say "cdl", that I could execute a...
