== Wifi ==
Most of the information regarding Wifi can be found in the [[Wifi|Wifi wiki page]]. <br>
For this kit, the setup should already be preinstalled, and you can skip to [[Wifi#Wireless_Networking| Wifi: Wireless Networking]] <br>
If when attempting to establish a connection in step 6 with:
<syntaxhighlight lang="text">/etc/init.d/wpa_supplicant start</syntaxhighlight>
the command seems to do nothing, attempt to restart the connection with:
<syntaxhighlight lang="text">/etc/init.d/wpa_supplicant restart</syntaxhighlight>
== Bluetooth ==
On the DEV-IOT6U, bluetooth is disabled by default. Enable it by:
<syntaxhighlight>gpioset gpiochip0 5=1</syntaxhighlight>
For serially connected bluetooth devices, you need to attach to them using hciattach:
<syntaxhighlight>hciattach /dev/ttymxc3 -t 30 bcm43xx 921600 noflow</syntaxhighlight>
Use '''hciconfig''' to check that hci0 device interface is enabled, and use <syntaxhighlight>hciconfig hci0 up</syntaxhighlight> to open and initialize the HCI device. See [https://linux.die.net/man/8/hciconfig hciconfig manual] for more information on configuring your Bluetooth device.<br>
<br>
From there
