1. Introduction
This document provides basic information on WB2072-00 Module development kits
hardware and software setup operations. It also describes the key information about the
associated software development package STSW-BNRGLP-DK and some common
troubleshooting cases.
The WB2072-00 is a low power Bluetooth® Low Energy (LE) module, compliant with the
Bluetooth® specification and supports master, slave and simultaneous master-and-slave
roles. The device also supports the Bluetooth Low Energy data length extension feature, 2
Mbps, Long Range and extended advertising features.
The following WB2072-00 kits are available:
• WB2072E00A development platform
The WB2072E00A development platform embeds a CMSIS-DAP programming/debugging
interface and features hardware resources for a wide range of application scenarios:
sensor data (accelerometer, pressure and temperature sensor), human interface (buttons
and LEDs), digital MEMS microphone and serial communication through USB virtual COM.

2. Getting Started
The WB2072E00A evaluation board is preprogrammed with Bluetooth LE Sensor
demonstration application for ST BLE Sensor app which allows to set and establish a
connection with a smartphone (iOS or Android) running the ST BLE Sensor smartphone app
(previously known as ST BlueMS).
Once connected, the WB2072-00 Module sends the data collected from the accelerometer
sensor and environmental sensor (pressure and temperature) to the ST BLE Sensor
smartphone app, which displays this information.
2.1 Powering up the evaluation board

When powered through USB, the evaluation board is also recognized on Windows Device
Manager as CMSIS-DAP device.

Note:
1. In Windows 10, no specific driver installation is required.
2. In Windows 7, the following driver must be installed before plugging the evaluation
platform:
https://os.mbed.com/docs/mbed-os/v6.0/program-setup/windows-serial-driver.html
3. The composite device (WebUSB: CMSIS-DAP) installation is not required, as this
functionality is not used.
In this context, once the evaluation platform has been recognized, it should also appear
under Device and drivers as a ST IDB011VX mass storage device:

Method one
Step 1. Press and hold the [PUSH1] button.
Step 2. Copy and paste the "BLE_SensorDemo_BlueMSapp_WB2072E00A.bin" binary
image into the [ST IDB011V1] mass storage device.

Method two
Step 1. Open BlueNRG-X Flasher Utility v4.0.0
Step 2. Select image file
Step 3. Select COM port
Step 4. Press “Flash”

2.3 Install the ST BLE Sensor app for smartphones (central role)
Launch the ST BLE Sensor app on the smartphone
It starts scanning for the Sensor Demo peripheral device. A device called “WB-2072LP”
appears on the screen.
Tap on the “WB-2072LP” name to connect to the selected WB2072E00A platform. The ST
BLE Sensor app enables notifications on the acceleration characteristic and on the
environment characteristics (pressure and temperature) and it displays the received
environment characteristics values on the screen.

3. Troubleshooting
The following section reports some tips to be followed if the WB2072E00A platform is not
recognized as a CMSIS-DAP device once connected to a PC USB port, or if user is not able to
connect/debug to the selected platform through a CMIS-DAP programmer/debug tool:
1. The WB2072E00A platform starts always in “MAINTENANCE” mode.
a. The USB_CMSISDAP firmware is not loaded. Follows the instructions in the
WB2072E00A user guide, section 2.9.4“USB_CMSISDAP firmware update” in order to
load the USB_CMSISDAP firmware. Please notice that this condition is not expected,
since the USB_CMSISDAP firmware is programmed at WB2072E00A manufacturing
time.
b. The application loaded in the WB2072-00 module makes the device continuously reset.
Since the RTSN signal is used at the startup by the USB_CMSISDAP firmware for
choosing to start in “MAINTENANCE” mode or not, it is necessary to disconnect the
RSTN signal of the WB2072-00 module from the USB_CMSISDAP. In order to do it, user
must perform the following steps:
1.) Remove the jumper JP4.

2.) Unplug the USB cable (if plugged).
3.) Plug the USB cable.
4.) The mass storage device “ST IDB011VX” should be present among the devices in
Windows “Devices and drives”.
5.) Put back the jumper JP4 (fitted position).
6.) Now user should able to use the USB_CMSISDAP firmware in order to fix the code
in the WB2072-00 module.
2. It is not possible to connect to the WB2072E00A, WB2072-00 module with the on board
CMSIS-DAP debugger/programmer.
a. The WB2072-00 could be under reset, or the SWD pins have been configured in a
different mode at the startup of the application, or the application sets the device in
DEEPSTOP modes which powers off the debug port.
In such cases, it is possible to recover the WB2072-00 status as follow:
1. Plug the USB cable in order to power up the board.
2. Press and hold the PUSH1 button.
3. Press the RESET button.
4. This operation activates the internal UART bootloader: now it is possible to connect
the CMSIS-DAP debugger/programmer to the WB2072-00 module.
