2 Setting up the evaluation board
2.1 Evaluation board setup
The EVK-NINA-W1 is delivered with the u-blox connectivity software installed on the module.
Before connecting the module, download and install the latest u-blox s-center evaluation software from the
u-blox website.
Plug in external supply power at connector J23 or connect J8 (USB type Micro B) to a USB host using the USB
cable. The status light (DS8) will turn green, indicating that the internal EVK 3.3 V is on.
When using the EVK-NINA-W131, before powering up the EVK, ensure that you have connected
the 2.4 GHz antenna with the U.FL antenna connector (J21). Failing to do so may cause
undesired operation. The EVK-NINA-W132 has an onboard antenna.
Be careful to check polarity before connecting external power supply to the EVK-NINA-W13
evaluation board. Center conductor is positive (+) and the ring is negative (-).
The current consumption during startup of the EVK can be high.
The operating system will install the correct COM port drivers automatically. The drivers will need to be installed
only when you connect the unit to a new computer for the first time. For more information about the COM
ports and their configuration, see the FTDI FT4232H Datasheet [3].
One COM port will automatically be assigned to the unit by the Windows OS. To view the assigned COM ports
on Windows 7, follow the steps mentioned below:
•
Open the Control Panel and click Hardware and Sound.
•
Click Device Manager in Devices and Printers. This will open the Device Manager window where you
can view the assigned COM ports.
2.2 Starting up
Perform the following steps to enable communication with the module:
1. Start the u-blox s-center evaluation software.
2. Use the default baud rate 115200, 8N1 with flow control.
3. You will now be able to communicate with the module through AT commands.
For a list of available AT commands, see the u-blox Short Range AT Commands Manual [2].
