1 Evaluation platforms
The STEVAL-IDB011V1, STEVAL-IDB011V2, STEVAL-IDB012V1 evaluation platforms
embed 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 STEVAL-IDB011V1, STEVAL-IDB011V2, STEVAL-IDB012V1 evaluation
boards are 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, BlueNRG-LPS 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
Three power options are available:
•Batteries - To power the selected evaluation board using batteries, 2 AAA batteries must
be inserted into the battery holder placed at the rear of the board or, alternatively, a coin
cell battery (CR2032) must be soldered Jumper JP2 set to position BAT on STEVAL-
IDB011V{1|2}. No change is required on STEVAL-IDB012V1 JP_VBRD jumper.
•USB - To power the selected evaluation board through USB, jumper JP2 set to position
USB on STEVAL-IDB011V{1|2}. No change is required on STEVAL-IDB012V1 JP_VBRD
jumper. Connect a USB cable to the available USB connector and to a PC USB port.
•External DC voltage: The supply voltage must be provided through JP2 pin 2 on
STEVAL-IDB011V{1|2}. The supply voltage must be provided through JP_VBRD pin 1 on
STEVAL-IDB012V1. The USB connection is not needed
Figure 4 . STEVAL-IDB011V{1|2} boards power options jumper JP2
When powered through USB, the evaluation board is also recognized on Windows
Device Manager as CMSIS-DAP device.

Figure 5 Windows Device Manager - CMSIS-DAP
NOTEs:
1. In Windows 10, no specific driver installation is required.
2. 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 (BlueNRG-LP kits) or a ST
IDB012VX (BlueNRG-LPS kit) mass storage device:
Figure 6 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, BlueNRG-LPS Sensor Demo peripheral
device. A device called “BlueNRGLP” appears on the screen for both BlueNRG-LP
and BlueNRG-LPS devices.
•Tap on the “BlueNRGLP” name to connect to the selected 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.

User can also plot the received acceleration values, by selecting the ST BLE Sensor app, Plot
Data window, Accelerometer option. The kit platform 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 evaluation board, it is
recommended to start with the reference demonstration applications provided
within the BlueNRG-LP, BlueNRG-LPS Development Kit SW package for
BlueNRG-LP, BlueNRG-LPS devices (STSW-BNRGLP-DK) available on the
STEVAL-IDB011V1, STEVAL-IDB011V2, STEVAL-IDB012V1 web pages:
•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.

8
IAR Embedded Workbench for ARM (EWARM) and Keil MDK-ARM tools
are needed for building the software applications running on the BlueNRG-
LP, BlueNRG-LPS microcontrollers.
WiSE-Studio IDE (GCC toolchain) is also supported from
STSW-BNRGLP-DK v1.1.0 or later.
Reference demonstrations applications are also provided.
NOTES:
1. The BlueNRG-LP, BlueNRG-LPS patches for IAR, EWARM and KEIL,
MDK-ARM toolchains are available on Project/Utility folder.
2. For a description of the available BlueNRG-LP, BlueNRG-LPS
demonstration applications and supported platforms, refer to
BlueNRG-LP, BlueNRG-LPS development kits user manual (Table 2.
Reference information, UM2735).
3. The BLE_SensorDemo_BlueMSapp.hex prebuilt binary image for
BlueNRG-LP, BlueNRG-LPS platforms are 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/STEVAL-
IDB011V2/STEVAL-IDB012V1 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. STEVAL-IDB011V1 platform is used as
reference on following guidelines:
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_LP 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

9
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_LPS 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, BlueNRG-LPS running
application in low power modes
•Debugging vs BlueNRG-LP, BlueNRG-LPS running application in low
power modes.
