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-B4 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
