2.3.1.2.2 Updating u-connectXpress connectivity software only
☞ 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.
1. Setup the serial port connection. See also Setting up the serial port.
2. Enter Software version identification AT+GMR command to find out the current version of your
u-connectXpress software.
3. Prepare the module to accept a binary file for download and start the bootloader at the
appropriate baud rate. Enter the Update software AT+UFWUPD command together with the
ConnectivitySoftware values defined in the NINA-B31X-CF-<version>.json file and the signature
in the NINA-B31X-SI-x.x.x-xxx.txt file. The bootloader must be running when the software is
“sent” to the module in the next step. Note particularly that <mode>=0,
<name>=ConnectivitySoftware, and <flags>=rwx. See also Prerequisites and Command
syntax.

NINA-B3 returns a series of “C” characters for as long as the bootloader is running.
