MediaTek LinkIt™ Smart 7688 Get Started Guide 1. Get Started With the LinkIt™ Smart 7688 Development Platform Welcome to the LinkIt Smart 7688 development platform quick start guide, this guide is based on using Windows with examples created in Python, however the same steps apply to Mac and Linux and for node.js — unless specifically noted otherwise. 1.1. Get the Hardware and Software This section describes the hardware and software you need to get started.
MediaTek LinkIt™ Smart 7688 Get Started Guide Step 3: Install Bonjour Print Service (For Windows 7 only) The LinkIt Smart 7688 development board uses mylinkit.local as its local domain. In Windows 7, you’ll need to install the Bonjour print service because mDNS is not supported. This helps your computer discover the LinkIt Smart 7688’s IP address within the local domain. For Windows 8 and later, Mac OS X and Linux, mDNS is supported and you can use mylinkit.local without additional software.
MediaTek LinkIt™ Smart 7688 Get Started Guide Figure 1 Providing power to the LinkIt Smart 7688 board After boot loader initialization, the boot up process begins, which takes about 30 seconds. Next, the Wi-Fi LED turns off; this means the system is ready to accept a Wi-Fi connection. Figure 2 shows how the Wi-Fi LED status matches the system state.
MediaTek LinkIt™ Smart 7688 Get Started Guide Step 2: Connect your PC to the LinkIt_Smart_7688 AP Open the Wi-Fi connection utility on your computer and connect to the access point named LinkIt_Smart_7688, as shown in Figure 3. Figure 3 Connecting to LinkIt_Smart_7688 AP The red LED will blink three times per second after you’ve connected to the LinkIt_Smart_7688 AP. If you have multiple LinkIt Smart 7688 boards, power only one of them to prevent a name collision.
