While the bootloader is running, send the u-connectXpress
NINA-B31X-SW-3.0.0-0.005.bin
file
to NINA-B3. The file is sent using XMODEM protocol.
5.
Once the binary file has been sent, NINA-B3 displays the greeting text
+STARTUP
. Enter the
Software version identification
AT+GMR
command again to make sure that the latest software
version is now installed.

Updating both the SoftDevice and u-connectXpress connectivity software
The SoftDevice is updated with AT commands using dual-banked approach, and as a SoftDevice
update overwrites the application currently flashed in the module it is also necessary to flash the
ConnectivitySoftware application after the SoftDevice update.
☞
You can send AT text commands to NINA-B3 to execute tasks using open-source terminal
emulator software that supports XMODEM, like TeraTerm or ExtraPuTTy. Alternatively, you can
send all AT commands described in this section using the s-center software in AT mode. See also
the s-center user guide [6].
Procedure
The examples in this procedure have been created and tested on EVK-NINA-B31 using TeraTerm.
