On boot...the Pi logs in stating some app is waiting..... the ip address and etc showing....
Here I'm assuming you are referring to plugging the pi into a monitor with a keyboard, after installing the pre-built image? On boot, the pre-built image will launch a node process to run the webserver. If you plug the pi into a monitor, you'll see the stdout of that process. I'm guessing this is what you are referring to when you say
"the ip address and etc showing...".
In order to use the command line when connecting to the pi with keyboard + monitor, you'll have to login as a user. The default username
pi and password
raspberry are still in place. These are standard with raspbian releases, but I just updated the scanner docs to note the login info as we'd like to avoid confusion wherever possible. After you see the boot sequence and info, and finally the output from the node webserver process, go ahead and try typing. It will prompt you for a login by showing something like
pi-dev-raspbian login: where "pi-dev-raspbian" is the hostname. It is asking for a login username. Type the default raspberry username
pi, and it should prompt you for a password. Type the default raspbian password
raspberry and you should have access to the command line. At which point you can run
sudo raspi config and perform the file system expansion from the GUI or simply enter the commands from the command line directly.
If you are not using a keyboard + monitor, then you can perform all of this more simply by ssh'ing into the rPi. Getting familiar with this process will make it easier to upgrade and modify the code on the rPi. Simply connect to the
Pi3-AP network, and then ssh into
172.24.1.1 with username
pi and password
raspberry. From a non-windows device you can likely use the hostname
pi-dev-raspbian instead of the IP address, but the IP address should work from any OS.
directions talk about version updates... I'm assuming you'd do a apt-get update xxxxxx but how from a browser? ...the commend line login is required isn't it?
The pre-built images are meant to make it easier for people to get started with a modified raspbian image. We'll try to release new images frequently, but the project uses a few codebases that update frequently, such as the sweep-sdk and sweep-3d-scanner. To stay up to date on bugfixes, tinker with the code yourself, or contribute to the project, you'll want to use the latest code. If you see new updates or bugfixes in sweep-sdk or sweep-3d-scanner that haven't yet made it into a pre-built image, you can simply ssh into the pi and pull the updated code from git. I've updated the wiki with some basic docs on how to update the code. Scroll down the bottom section titled "Updating existing code". This isn't necessary right now, as the latest image is up to date. But code changes daily.
Glad to hear you are diving into the project. You're one of the first, so if you encounter hiccups or would like some improved documentation, please let me know! And expect things to evolve rapidly.
