DFU process & bonding

[Mohamed O.Abouzeid]

I loaded the "dfutarg" dfu program "dual bank version" to the development kit & then used this dfu program to perform firmware over the air, the firmware I need to upload to the development kit through fota is secured by bonding & MTIM, also this firmware includes dfu to be able to perform updates to the firmware, my problem is that when I try to update the firmware " I already downloaded throgh FOTA " again using teh Dfu service, it didn't work, it didn't advertise the DK as "dfutarg" & I can't update it again,

I think that's due to the security feature of the firmware, the "dfutarg" has no security, no bonding, no MTIM & the link between the central & the device "FOTA firmware" is secured link !! what do you think? ?

thank you for your great effort ;)

Once the firmware is uploaded, it will be executed so so you will not see dfu. There is a button (don't remember which) to press at boot time to get back into dfu mode.

@Nguyen Hoan I'm using buttonless DFU, the dfu service in the new firmware will be responsible for jumping into the dfu mode which is not happened since I added the MITIM & bonding
