The
bin
fi
le
contains only the application code and requires the
RAK DFU Tool
to upload it to the module.
The
hex
fi
le
includes both the bootloader and the application code. To upload it, you need to use the
STM
32
CubeProgrammer
.
WARNING
Uploading the
.hex
fi
le using STM
32
CubeProgrammer will erase all con
fi
gured data on the device.
RAK
3272
S uses UART
2
serial pins to upload the latest
fi
rmware.
NOTE
The
RAK
3272
S
should automatically enter BOOT mode when the
fi
rmware is uploaded using the
RAK DFU Tool
or
WisToolBox
.
If BOOT mode is not initiated, send the
AT+BOOT
command to start bootloader mode.
