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
Connectivity Software values defined in the
NINA-B22X-CF-<version>.json
file and the signature
in the
NINA-B22X-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.
NINA-B2 returns a series of “
C
” characters for as long as the bootloader is running. The XMODEM
download is ready to begin from the host.
4.
While the bootloader is running, send the u-connectXpress
NINA-B22X-SW-4.0.0-0.003.bin
file
to NINA-B2.
5.
Once the binary file has been sent, NINA-B2 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.
For more information about the parameters, see the Software update
+UFWUPD
command in
u-connectXpress AT Commands Manual [1], u-connectXpress bootloader protocol specification [8],
and u-connectXpress user guide [5].
