PAN9028 Wi-Fi/Bluetooth Module 2 Overview
Quick Start Guide Rev. 1.0 Page 6 of 34
2 Overview
The PAN9028-IMX is a development platform for the Wi-Fi/Bluetooth®PAN9028.
The PAN9028 requires a fairly powerful host processor that executes the low-level Wi-Fi driver
as well as some high-level Wi-Fi application software. Because of this, the Wandboard was
chosen as the hardware platform. It is based on the well-known and powerful
NXP®i.MX6 processor and provides a separate µSD card slot for attaching peripheral devices
like the PAN9028-MSD.
A Linux®-based installation was chosen as the software platform. The Linux kernel provides an
established environment for running a Wi-Fi driver and the available Wi-Fi applications make it
possible to use the PAN9028 to its full extend.
Two different software environments are available for the PAN9028-IMX: Ubuntu Linux and
Yocto Project Linux.
The Ubuntu Linux based environment is available to showcase all the different possibilities of
the PAN9028 which also allows the user to experiment with the system, using a
graphical user interface (GUI). This environment is described in this Quick Start Guide.
The Yocto Project Linux based environment is available to showcase the easy integration into a
customer-specific build environment. This environment is described in the “Development Guide”
which is available separately.
Both environments provide access to the Wi-Fi and Bluetooth features of the PAN9028 by
supplying a web server running on a Wi-Fi access point. After a connection to that access point
has been established, it is possible to interact with the PAN9028 with the browser.
The Ubuntu Linux based environment additonally provides a GUI that many are familiar with
and that allows the user to explore the PAN9028 using a full-featured Linux desktop
environment.
For related documents please refer to 9.2 Product Information.
2.1 Wi-Fi Features
The PAN9028 provides a web server interface through a Wi-Fi access point that devices can
connect to. It can simultaneously connect to another Wi-Fi access point and relay any internet
connectivity from there.
All Wi-Fi features can be controlled from the GUI as well.
2.2 Bluetooth Features
It is possible to select different Bluetooth applications through the user interface, provided by
the web server. The Bluetooth Basic Rate A2DP profile allows the PAN9028-IMX to become a
Bluetooth audio sink. It is possible to playback audio from a remote device that is connected via
Bluetooth Basic Rate.


PAN9028 Wi-Fi/Bluetooth Module 2 Overview
Quick Start Guide Rev. 1.0 Page 7 of 34
Alternatively, the PAN9028-IMX may become a Bluetooth Low Energy proximity beacon, using
the AltBeacon Protocol, which may be used for indoor navigation.
All Bluetooth use cases have been implemented, using Blue SDK from OpenSynergy.


PAN9028 Wi-Fi/Bluetooth Module 3 Installation
Quick Start Guide Rev. 1.0 Page 8 of 34
3 Installation
The PAN9028-IMX consists of the following components:
•PAN9028-MSD (µSD card form factor)
•Wandboard Dual (WB-IMX6U-BW)
•USB power cable as power supply
•µSD card with Ubuntu Linux image (already inserted)
The following additional components are not included, but may be required depending on the
use case:

Inserting µSD
Ideally the µSD card with the Ubuntu Linux image is already inserted in the µSD card slot on the
system-on-module, so that the Wandboard will boot from it, if not:
1. Turn around the Wandboard. The audio connectors are facing downwards.
2. The µSD card slot of the system-on-module can be found on the left side.
3. Gently press the connector.
➔The µSD card will spring out.
Remember the orientation of the contacts. The contacts must face upwards
when the µSD card is inserted.
3.2 Using Device for Remote Control
Certain functions of the PAN9028-IMX can be remote controlled via Wi-Fi. A Wi-Fi capable
device for controlling is needed.
Disabling a Mobile Data Plan
If a mobile device is used that has a SIM card, which supports a mobile data plan for accessing
the internet, it is recommended to switch off the mobile data plan while working with the
PAN9028-IMX. The Wi-Fi access point, provided by the PAN9028 initially, does not provide
access to the internet.
If a mobile plan is available, Android may route any network traffic through the mobile data plan
to the internet, instead of using the seemingly non-functional access point.
To avoid confusion and force Android to route the network traffic through the access point of the
PAN9028, it is recommended that the mobile data plan is switched off.
