So you have added the code from the experimental buttonless dfu example to the ANCS example in SKD 12?

and softedevice S110 version not S130

@Bjørn Spockeli it was SDK 10

When you say "it was working previously" was this with SDK v11 or an older version(not SDK v12)?

but it was previously working with bonding, I don't think that this is the problem !!! , I put it like that but no gain.

Is this for the nRF52 or nRF51? It should be set to a multiple of the flash page size, 4kB on the nRF52 and 1kB on the nRF51.I suggest that you set it to 3* flash page size, i.e. 0xC00 for the nRF51 and 0x3000 on the nRF52.

So, it's used in bootloader what is the value to be set on DFU_APP_DATA_RESERVED ? it's now 0x0000

The header file is used in the bootloader, not the application. If you're using the bootloader example from SDK 12, then it should be a part of the project.

I mean my code is not using this file, should I just include it without any calls for its parameters ? ?

RE: DFU & IOS & Bonding

Mohamed O.Abouzeid — Thu, 22 Sep 2016 08:05:41 GMT

@Bjørn Spockeli I don't include this file, can u send me the version you have ?

@mohamed: The DFU_APP_DATA_RESERVED define is found in nrf_dfu_types.h.

@Hungbui I didn't find APP_DATA_RESERVED at all, what should I do and how to define it and how ?

RE: DFU & IOS & Bonding

@mohamed: Have you found and modified APP_DATA_RESERVED as suggested ? It's the AppData part as shown here.

@hungbui here is my pstorage configuration:

				#elif defined NRF52
				#define BOOTLOADER_ADDRESS           (PSTORAGE_FLASH_EMPTY_MASK)
				#endif

				static __INLINE uint32_t pstorage_flash_page_end()
				{
				   uint32_t bootloader_addr = BOOTLOADER_ADDRESS;
				  
				   return ((bootloader_addr != PSTORAGE_FLASH_EMPTY_MASK) ?
						   (bootloader_addr/ PSTORAGE_FLASH_PAGE_SIZE) : NRF_FICR->CODESIZE);
				}

				#define PSTORAGE_FLASH_PAGE_END pstorage_flash_page_end()

				#define PSTORAGE_NUM_OF_PAGES       2

@HungBui yup, I'm pairing by this pop up notification to pair or cancel, then it's paired in application mode. okay I'm reading your link now & would see if it's applied in my code or not but I tried it before and it was working with me. I'm using the device manager and pstorage.

RE: DFU & IOS & Bonding

Hung Bui — Thu, 08 Sep 2016 11:04:57 GMT

@mohamed: How did you bond to the device (when the "Pair with this device?"pop up appear) ? You bond when you are in bootloader mode or you bond when you are in application mode (ANCS)?

If you bond in application mode and you don't want to lose bond after you do DFU, you would need to define how much space you want to reserve for the bond information.

If you are using the secure bootloader from SDK v12, you can have a look here

You would need to match the APP_DATA_RESERVED size with the size of the fds (or pstorage) you used for peermanager/device manager. On SDK v12 it's 3 virtual page (3kB on nRF51 and 12kB on nRF52)

@RogerClark , I can't use buttons in my application, I'm entring the bootloader by enable notification on DFU packet control & send 0x01 on the same characteristic, before it disconnects immediately & start advertising as "dfutarg" but no it discconnects but take some time & advertise as dfutarg with erasing bonds and I can't connect to it or even my application again. if it's possible I would try on both IOS and android but it seems to be useless for IOS because once it's added to paired devices, I couldn't jump even to the bootloader.

RE: DFU & IOS & Bonding

Roger Clark — Thu, 08 Sep 2016 03:16:22 GMT

How are you entering the bootloader ? Via a button on a GPIO pin, which is pressed during power cycling (or resetting)?
