Hello,
I installed GoPiGo OS on my GoPiGo3 and I want to connect it to the internet. The problem is GoPiGo OS doesn’t see the built in Wi-Fi adapter in the raspberry and the WIFI dongle works as a hotspot and can’t be used to connect to my WIFI.
Can anyone help to connect the raspberry pi to the internet ?
That is a serious issue, indeed, that I faced a few years back with a Raspberry Pi 3 and Raspbian Jessie.
I have read that GoPiGo OS 3.0.1 cannot be configured for local router access over a USB WiFi dongle, so my suggestion is to use Raspbian For Robots pre-configured with your network specifics and ssh.
The official instructions are here
This is how I do the setup “headless” - preconfiguring my router SSID/password and ssh remote access, (so I do not need to attach a keyboard, display, mouse, and ethernet cable):
GoPiGo3 Setup (Public Version)
*** Download Raspbian For Robots (2020_10_17 version is no longer available)
https://sourceforge.net/projects/dexter-raspbian-for-robots/files/2019_12_12_Raspbian_For_Robots_Buster_experimental_by_Dexter_Industries.zip/download
*** Current Instructions
https://www.dexterindustries.com/howto/install-raspbian-for-robots-image-on-an-sd-card/
*** Flash SD card with Raspberry Pi Imager / Etcher
Select the Raspian For Robots zip file
Select the 16GB SD Card
Flash
=== Mount the card to allow headless configuration
- Pull card out, reinsert for next steps
=== Enable SSH
- create a file called "ssh" (or ssh.txt) in the Boot partition
(touch /boot/ssh)
=== Setup WiFi Headless
- create the file /boot/wpa_supplicant.conf
(quote chars must be straight up/down, traditional, not slanted/matched Unicode chars
use ssid="XXXX"
country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid="XXXX"
psk="XXXX"
key_mgmt=WPA-PSK
}
=== disable ipv6
Browse the disk (boot)
Rt Click on System Volume Information->Open Terminal Here
cd ..
cp /boot/cmdline.txt /boot/cmdline.txt.bak
nano cmdline.txt
add to end of line/file:
ipv6.disable=1
save, exit editor
- eject disk
==== Raspbian First Boot
-insert micro SD card
-power on
- on mac: arp -a to check IP
=== First Login
ssh pi@10.0.0.XX
The default login for Raspbian For Robots is username pi with the password robots1234
=== is see SSH HOST KEY verification failed
on mac: ssh-keygen -R 10.0.0.XX
Login: username: pi password: robots1234
=== Configure for locale, timezone, and expand filesystem to fill card
$ sudo raspi-config
(You can exit menus by using Tab key, move to Finish, enter key)
change password to XXXXX
Network Options: change hostname to XXXX
change Localisation:Locale -> remove en_GB, add en_US.UTF8
default local: en_US.UTF-8
change Localisation:Timezone-> US->Eastern
change Localisation:WiFi Country->US
Interfacing:PiCamera enable
reboot now yes
=== LOG IN Again
pi:XXXXXX
=== Change TightVNC password ====
at a terminal:
vncpasswd
<new password>
<new password>
n (do not set up a view only "no password" login)
=== update now
sudo apt-get update
sudo apt-get full-upgrade
==== Check TEMPERATURE
To view the Pi's temperature
vcgencmd measure_temp
It's generally a good idea to keep the core temperature below 70 degrees

====== Raspian4Robots WiFi Indicator ====
When in Raspbian or Raspbian for Robots, once the GoPiGo3 is connected to a WiFi access point, the antenna LED will be a pale yellow, very different from the green and blue for DexterOS.
This gives the user a nice feedback that the robot is connected to Wifi and removes the guessing game.
This means a new service is installed: antenna_wifi.service which runs every 10 seconds, for less than 0.2 sec on average. A user can always choose to disable this service with the standard
sudo systemctl disable antenna_wifi.service
