Thanks for the response! I'll give the solutions above a try.

Hi,

You are working with a very old nRF5 SDK, the latest nRF5 SDK for the nRF51-series is nRF5 SDK v12.3. I could find some example for nRF5 SDK v10 below that may be helpful if you want to stay on older SDK.

Typically you set DEVICE_MANAGER_MAX_BONDS to something larger that the number of bonds you want to support, you should in any case delete the bonds that are not needed/used.

To delete one bond you can use:
https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk51.v10.0.0/group__dm__cntxt__mgmt__api.html?cp=4_0_2_6_2_11_4_2_3#gaf267e34f237c41665fd9df15dd32c531

Also, maybe you can check out this thread on devzone:
https://devzone.nordicsemi.com/question/39249/how-to-use-dm_device_delete/

Alternatively, I do notice than one example we have on github do execute a system_reset() after all bonds are deleted. Likely to ensure that state machine and variables are set back to the correct state afterwards:
https://github.com/NordicSemiconductor/nRF51-ble-peripheral-bond-handling/blob/master/main.c

It's slightly brute force method, but it will always work.
