1 Development platforms
The STEVAL-IDB011V1 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.
Figure 1 STEVAL-IDB011V1 development board
2 Getting Started
The STEVAL-IDB011V1 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 BlueNRG-LP device 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
Two power options are available:
•Batteries - To power the selected evaluation board using batteries, 2 AAA batteries must
be inserted into the battery holder BATT1 placed at the rear of the board or, alternatively, a
coin cell battery (CR2032) must be placed on BATT2 region. Jumper JP2 set to position
BAT.
•USB - To power the selected evaluation board through USB, jumper JP2 set to position
USB. Connect a USB cable to the micro-USB connector and to a PC USB port.

Figure 2 . Board power options (JP2)
When powered through USB, the evaluation board is also recognized on Windows
Device Manager as CMSIS-DAP device.
Figure 3 Windows Device Manager - CMSIS-DAP
NOTEs:
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:
Figure 4 ST IDB011VX mass storage device
Once powered (batteries or USB), the Sensor Demo application for ST BLE
Sensor app starts advertising, waiting for a smartphone to connect to it.
2.2 Install the ST BLE Sensor app for smartphones (central role)
Two versions (Android and iOS) of the smartphone ST BLE Sensor app are
available for download on the specific web pages (Table 2. Reference
information, Android & iOS Sensor App).
Install the ST BLE Sensor App on the selected smartphone.
2.3 Run ST BLE Sensor app for smartphones
Launch the ST BLE Sensor app on the smartphone
•It starts scanning for the BlueNRG-LP Sensor Demo peripheral device. A device
called “BlueNRGLP” appears on the screen.
•Tap on the “BlueNRGLP” name to connect to the selected STEVAL-IDB011V1
platform. The ST BLE Sensor app enables notifications on the acceleration
characteristic and on the environment characteristics (pressure and

5
temperature) and it displays the received environment characteristics values on
the screen.
Figure 5 ST BLE Sensor smartphone app environment characteristic notifications
User can also plot the received acceleration values, by selecting the ST BLE Sensor app, Plot
Data window, Accelerometer option. The STEVAL-IDB011V1 accelerometer sensor values (X, Y,
Z) are displayed on a graphical chart.

3 Software demonstration applications
In order to develop a software application for the STEVAL-IDB011V1 evaluation
board, it is recommended to start with the reference demonstration applications
provided within the BlueNRG-LP Development Kit SW package for BlueNRG-LP
devices (STSW-BNRGLP-DK) available on the STEVAL-IDB011V1 web page:
•Unzip the file, launch the related installer and follow installation steps.
•Wait for the package installation to complete.
•The Projects folder in SW package contains the available demonstration
applications, projects, sources and header files.
The Bluetooth LE Sensor Demo application for ST BLE Sensor app projects
and header and source files are available on
•Projects\BLE_Examples\BLE_SensorDemo_BlueMSapp folder.

7
IAR Embedded Workbench for ARM (EWARM) and Keil MDK-ARM tools
are needed for building the software applications running on the BlueNRG-
LP microcontroller.
NOTES:
1. For a description of the available BlueNRG-LP demonstration
applications and supported platforms, refer to BlueNRG-LP
development kits user manual (Table 2. Reference information,
UM2735).
2. The BLE_SensorDemo_BlueMSapp.hex prebuilt binary image for
BlueNRG-LP platform is also provided within the Development Kit
software package, in the
Firmware\BLE_Examples\BLE_SensorDemo_BlueMSapp folder.

4 Troubleshooting
The following section reports some tips to be followed if the STEVAL-IDB011V1 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 STEVAL-IDB011V1 platform starts always in “MAINTENANCE” mode.
a. The USB_CMSISDAP firmware is not loaded. Follows the instructions in the
UM2735 manual (Table 2. Reference information, UM2735), 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 STEVAL-IDB011V1 manufacturing
time.
b. The application loaded in the BlueNRG-LP device 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 BlueNRG-LP from the USB_CMSISDAP. In
order to do it, user must perform the following steps:
1. Remove the jumper JP5.
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 JP5 (fitted position).
6. Now user should able to use the USB_CMSISDAP firmware in order to fix the
code in the BlueNRG-LP.
2. It is not possible to connect to the STEVAL-IDB011V1, BlueNRG-LP device with the
on board CMSIS-DAP debugger/programmer.
a. The BlueNRG-LP 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 BlueNRG-LP 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 BlueNRG-LP.
NOTES:
1. Please refer to the STSW-BNRGLP-DK, C:{Installation_Path}\
ST\BlueNRG-LP DK x.x.x\Docs\BlueNRG-
LP_Debugging_Guidelines\BlueNRG-LP_Debugging_Guidelines.html
document for useful guidelines to be followed in these scenarios:
•CMSIS-DAP programming vs BlueNRG-LP running application in low
power modes
•Debugging vs BlueNRG-LP running application in low power modes.
