Problem

Unable to configure wlan

I was able to configure WLAN easily in Raspbian OS using /etc/dhcpcd.conf as shown here on the same Raspberry Pi.

Add your dhcp config to /etc/network/interfaces.d/wlan0 and try again.
Feel free to reopen this issue again if it is not working.

@firecyberice Can you please give an example and update the user data here as well?

Please have a look at: hypriot/blog#60

The next HypriotOS 1.8.0 will be easier to activate WiFi.

I thought that adding this to your YAML files was supposed to take care of this? I have been trying a few dozen different things and this isn't working for me either. Have most recent version of flash.

By the way, great work. Loving everything so far. Issues are very few.

With HypriotOS up to 1.7.1 you have to change the /boot/config.txt and turn off uart. Hypriot 1.8.0 will have another default so you don't have to care about that.
