Setting up the evaluation board
The EVK-NINA-W10 is delivered without any software (open CPU) and the software must be
developed by the user.
The EVK-NINA-B2, EVK-NINA-W13 and the EVK-NINA-W15 is delivered with the ublox connectivity
software pre-flashed on the module.
⚠
The module is designed to be used only with the applicable software and only compatible software
can be flashed 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 evaluation board with external antenna, 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.
⚠
Be careful to check polarity before connecting external power supply to the evaluation board.
Center conductor is positive (+) and the ring is negative (-).
⚠
The current consumption during startup of the evaluation board 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 [6].
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.
2.1
EVK without software (open CPU)
The chapter is applicable to the following EVKs.
•
EVK-NINA-W101
•
EVK-NINA-W102
When using the NINA-W10 open CPU variant, it is not possible to download the u-blox connectivity
software. Use the software developed and compiled using the Espressif SDK on this variant.
Information on how to build and FLASH the module when using Espressif SDK is available at the
following URL - http://esp-idf.readthedocs.io/en/latest/get-started/index.html.
This URL webpage provides information on how to set up the software environment using the
hardware based on the Espressif ESP32 such as NINA-W10 and also how to use the ESP-IDF
(Espressif IoT Development Framework).
The following steps must be performed to compile, flash, and execute a program on NINA-W10:
•
Set up the Toolchain
o
Windows, Mac, and Linux is supported
•
Get the ESP-IDF
