This case is more than 5 years old at this point, and the Simon you're looking for is no longer with Nordic I'm afraid. Please open a new ticket where you describe your issue in detail. I'd strongly recommend moving to the nRF Connect SDK or at the very least nRF5 SDK v17.1.0, where we added a lot of fixes to the peer manager and more support for the nRF52833 SoC.

Best regards,

Simon

Device: nRF52833 on CorvoDWM3001C (pca10100)
Soft Device: s140
SDK Version: 15.0

Hi Simon

I am trying to use your code examples. But despite adding files related to peer manager to file explorer and User Include Directories i still get some errors. i try different versions of SDKs and even compare sdk_config.h file line by line with ble_app_gls example which has secure key option. i get following errors. Is there any chance that you share the whole zip file or sdk_config.h file? Also I am adding my sdk_config.h file to attach.

ERROR:
Output/Debug/Obj/ble_app_uart_pca10056_s140/main.o: in function `pm_evt_handler':

Are you using any of the DFU bootloader examples in the SDK? The DFU Bootloader examples in the SDK does not use the Peer Manager, except for the Buttonless DFU application, which doesn't contain any DFU functionality itself (need to flash a bootloader in addition), only the possibility enter DFU mode.

Could you be more specific? What DFU example are you using? One of the DFU Bootloader examples (located in SDK\examples\dfu)? The Buttonless DFU example or do you have your own custom solution.

I don't think

I have used the code you gave me, I can add static key connections and bindings, but I have another point that I don't understand. I need to use peer_manager when using static keys; I am also using DFU function; DFU Also includes peer_manager; both functions use peer_manager; how to avoid conflicts in configuring peers?

I have attached two examples, respectively the ble_app_uart central and peripheral examples, where I have modified the projects to bond using a static key (For some reason it didn't work uploading the whole project in zipped format, so I attached the main.c files). Use the examples as a reference when implementing your solution. Be aware that the solutions may contain bugs/errors since I haven't tested it extensively.

This seems to be very useful, but unfortunately, my English is very poor, it is difficult to understand the contents, please help provide the client input key routine

Thanks.

I would recommend you to take a look at the Peer Manager, which is a library used to simplify the security process (bonding, pairing and encryption). Use the Message Sequence charts for passkey bonding when implementing your solution.

Best regards,

Simon
