2.2.1.1 s-center evaluation software
s-center is convenient to use together with ANNA-B412 when running the AT commands supported
in u-connectXpress. It also includes predefined functions. Install
s-center evaluation software [7] and
set the baud rate to 115200 with 8N1 configuration and flow control. All available AT commands are
described in the u-connectXpress AT commands manual
[3] .
To get started with the u-connectXpress software for USB-ANNA-B412, see the user guide [5] .
USB-ANNA-B402
ANNA-B402 is the Open CPU variant of ANNA-B4. You can use the legacy Nordic SDK or nRF Connect
SDK for application development, but the latter is recommended for use with the USB-ANNA-B402
evaluation board.
2.2.2.1 nRF Connect SDK
The nRF Connect SDK allows developers to include new features, such as Bluetooth Direction Finding
and Bluetooth LE Audio, into customer applications. To use USB-ANNA-B402 together with the
Zephyr-based nRF Connect SDK:
• Create your own board definition
• Build the examples in the nRF Connect SDK to use this board definition
For more information about performing these tasks, see the Software section of the ANNA-B4
system integration manual
[1] . Reference code for u-blox Open CPU modules is available from the
u blox short range open CPU github repository [6] .
2.2.2.2 Nordic Semiconductor SDK
The older (not recommended for new designs) nRF5 SDK is natively a “bare - metal” kit that does not
depend on a Real Time Operating System (RTOS). Notably, new features beyond Bluetooth LE 5, like
Bluetooth Direction Finding and Bluetooth LE Audio, are not supported in this SDK.
To use the USB-ANNA-B402 together with the legacy Nordic Semiconductor SDK:
• Create your own board file
• Adapt the examples in the Nordic Semiconductor SDK to use this board file
For more information about these tasks, see the Software section of the ANNA-B4 system
integration manual
[1] . See also the u-blox short range open CPU github repository [6] .
2.2.2.3 Software debug options
To debug using the onboard J-Link connector on USB-ANNA-B402, use an external debugger
connected to the J-link 6-Pin Needle Adapter with the SEGGER J-Link software
[4] .
2.2.2.4 Flashing software
USB-ANNA-B402 can be flashed using the J-link connector or over UART using the preflashed
bootloader on the ANNA-B402 module. See also the ANNA-B4 SIM
[2] .
