Updating software with AT commands
☞
You can send AT commands to NINA-B3 to execute certain tasks over the serial interface, 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. The examples given in this procedure have been created and tested on EVK-NINA-B31
using TeraTerm. See also the u-connectXpress AT command manual
and Bootloader protocol
The bootloader must
be running when the software is “sent” to the module.
You start the bootloader
using either:
•
AT commands
•
Pressing the SW1 and SW2 buttons simultaneously during a module reset (initiated by setting
RESET_N
low).
The bootloader prompt “
>
” is seen
when the boot loader mode has started.
