Pairing code examples for an NRF51822 based peripheral.

[Robin]

Hello nRF world,

We have custom peripheral board based on the nRF51822 and need to be able to pair it with a host.  Does anyone have a well documented example of code for doing so?

Thank you kindly,

An update:  I have taken the advice of a related ticket and merged our code into the ble_app_gls example to attempt pairing. 

However, although all modules compile independently, there appears to be a memory segmentation problem when linking.  It appears to be associated with the fstorage for fds code, but I cannot determine the fix.  The initial error messages are as follows:

Output/Debug/Exe/iDrink.elf section `.fs_data' will not fit in region `UNPLACED_SECTIONS'

Subsequently several errors ensue...

region `UNPLACED_SECTIONS' overflowed by 16 bytes

Output/iDrink Debug/Obj/fstorage.o: In function `check_config':

undefined reference to `__start_fs_data'

undefined reference to `__stop_fs_data'

... and on ad-nauseam...

What file might I be missing to define this unplaced section in memory?

Thanks again, in advance,

You just needed to add one line in flash_placement.xml file in your project

  <MemorySegment name="$(FLASH_NAME:FLASH)">
    ....
    ....
	<ProgramSection alignment="4" keep="Yes" load="Yes" name=".fs_data" address_symbol="__start_fs_data"  end_symbol="__stop_fs_data" />
  </MemorySegment>

After that your project compiles fine.

Hello Susheel,

I believe peer manager is in the code.  Do you not see it in the uploaded project?

I missed to see that, I will see if there is any initialization of peer manager in that project tomorrow, Its late here in Norway now.

Hello Susheel,

I am closing this case I have changed the scope and added a new case for adding secure pairing/bonding to a ble_uart based application.  Please remove all attached files and make this case public.

Thanks

Hello Susheel,

I am closing this case.  Most of the question have been resolve and we are on to the next set of concerns.  I have generalized where we are and what needs to be done next and the help we could use in case # 220048.

Thank you for your continued assistance.  I look forward to your responses in the mentioned case.
