In contrast to the s-center configuration, UART hardware flow is not used for updating software
using AT commands. The file download uses standard XMODEM-CRC16 protocol and 128 byte
packets.
Prerequisites
As a prerequisite to updating software using AT commands, you must open the JSON file included in
the download container and make note of the defined values to be parsed with the update command.
You also need to copy the signatures given in the related txt files, as shown in
. This
information is needed during the install. The defined values to include in the command, together with
the signature file (
NINA-B31X-SI-x.x.x-xxx.txt
), are shown in

Command syntax
You use the software update command
AT+UFWUPD
with following syntax to update both the
u-connectXpress and SoftDevice software.
AT+UFWUPD=<mode>,<baud_rate>[,<id>,<size>,<signature>,<name>,<flags>]
The defined values for each parameter are shown in
