iOS devices may not show the live device name "DFUxxx" that is placed in the
radio packets due to internal look-up table use. It will only update the device
name after a connection was successfully established. Vice versa, when re-
booting the device after using the FOTA mode, iOS will still show "DFUxxx" as
device name until a connection has been setup to the module again.
Now, any Bluetooth
®
LE device hosting an application that understands the commands of the
Nordic nRF52 Bluetooth
®
LE DFU Bootloader can connect in order to update the Proteus-II
firmware.
The DFU application of the used App (see Table
) is such an application. For more details,
please refer to chapter
. As soon as a connection has been set up,
turns off
again and
turns on.
The implemented Nordic nRF52 Bluetooth
®
LE DFU bootloader uses a dual
bank method to update the firmware. Thus, the old firmware is only replaced
once the new firmware has been transferred and authenticated successfully.
This prevents the module from being flashed with a faulty firmware.
An OTA firmware update will take several minutes to be performed, the duration
is also dependent how much of the firmware shall be updated (application only
or complete update).
