Distilled to the essentials, Arduino and Pi single board computers (SBC) are not similar at all.
Pi single board computers have no onboard operating system (OS) and is a huge advantage. The OS is on the micro SD card, and the Pi ROM merely loads the OS from the SD card. This is different from Arduino. Arduino’s are good process controllers, lousy computers. Rant closing now.
Your brief insight is appreciated!
I am up and running. I do need to enable SSH and see if I can change the SSID and password that way.
Thanks to everyone for your help.
Just to summarize what I’ve observed: Special characters in passwords cause problems, even if they’re quoted or escaped (with a back-slash).
If you have Monitor & Keyboard connected to RPi, issue following commands (assuming you are using piaware sd card image)
sudo touch /boot/ssh
sudo reboot
.After reboot, the SSH will be enabled.
The PiAware SD card image has a Raspbian OS with a default language of UK English. My setup is thus and makes sense since RPi is a UK company. The " and \ characters are located on different keys on US and UK keyboards. The ? character is the same on both layouts. So if you were banging in input on a US keyboard it may be interpreted differently than what you think. Just a thought on what your issue may have been.
That’s an interesting thought. But if I see a backslash character (glyph), that’s what I’d expect the software to interpret it as. The numeric representation of backslash in ANSI (Latin-1, to be more precise) should match the glyph, regardless of what keystroke generates it.
Just because you seem to be curious, you can check this command after modifying /boot/piaware-config.txt and rebooting:
cat /etc/wpa_supplicant/wpa_supplicant.conf
That’s the file that will have the actual wifi configuration.
Also you’ve been using the keyboard your used to when configuring the sd-card before putting it into the RPi.
So that would be the file to edit if I want to change the WiFi configuration (i.e. change SSID/Password)?
Well no, on the piaware sd-card image that file will be automatically generated from /boot/piaware-config.txt wifi settings.
But you can check what happens.
