I’ve got a Pi Zero 2W in my travel bag to tinker while I travel, but I’m discovering the difficulties of getting this little thing on a new wifi network without ethernet, monitor, and keyboard.
I’ve seen a number of posts addressing this, both DietPi and Raspbian, and understand the options to flash a new card and modify dietpi-wifi.txt or find a way to access wpa_supplicant and modify that. However, flashing a new card wipes anything I have setup, and my Mac doesn’t let me get to wpa_supplicant in the ext4 sector (though it seems like maybe some 3rd party paid software might enable this).
Is it possible to enable USB ssh with DietPi so I can access my Zero2 directly from my Mac with a USB cord, then add the wifi network? I tried the steps in (this blog post) on a fresh dietpi flash and it seemed to work, as an “Allow RNDIS/Ethernet Gadget” request popped up.
But then what? Of course it won’t be ‘ssh pi@raspberrypi.local’ like in that blog, I tried ‘root@dietpi.local’ and a couple similar variations with no luck.
Any ideas?
(Also open to alternative ideas of how to add my Zero2 with current configuration to a new wifi network with only a macbook, a usb cord, and a microSD reader.)
The question is: What is the use case? What are you planning to do with the Zero 2? Do you want to connect to the WiFi of a hotel? Perhaps you can describe your scenario in more detail.
Yes, that’s just like the blog I linked, but both ssh to pi@raspberrypi.local … what’s the .local address for dietpi? I tried a few guesses and none worked
yes, I want to connect the Zero2 to other wifi such as hotel, airbnb, relative’s house, etc. I don’t always know the wifi credentials before arriving, so I can’t add them while still at home on my own network.
I guess this is not workin in gadget mode, not sure which IP address is used in this case.
@brtravel what are you planning to do once connected to WiFi? because it could be a challange to access the device as you might not know the IP and some hotels might block communiction between device connected to hotel wifi.
Well in this scenario it’s not on any network yet, which is the whole difficulty, trying to give a headless device the wifi credentials when it’s not yet on any network. I assume like in that blogpost that using .local is the way to do this with USB SSH.
I’ll try again when I’m back at computer, I left the default settings on device name and I tried both root@dietpi.local and root@DietPi.local
yeah, that was a reply to Jappe who was suggesting using the IP set by DHCP or static, which in this case wouldn’t exist yet(?)
my use case is pretty open still, I got this Pi Zero 2 just to tinker and threw it in my minimalist travel bag and am currently visiting family and realized I’m unable to easily get it on the network. Tailscale, Pihole, and Samba likely.
