Error on disconnection when bond manager save data : NRF_ERROR_DATA_SIZE

[Sébastien Despont]

Dear developer zone,

I am using nRF51822 with soft device and SDK 4.4.2

My device return an error on disconnection when the ble_bondmngr_bonded_masters_store function call the soft device function sd_ble_gatts_sys_attr_get which return error "0x0C" : NRF_ERROR_DATA_SIZE

It occurs each times, but only when a central has been paired.

Is there someone to help me?

Best regards

Unfortunately, the person who really help me by posting the comment above has no account in this developer zone.

Therefore, I post the answer in his name and thanks him a lot for figuring my problem out!

I had the same problem and fixed it by increasing BLE_BONDMNGR_CCCD_COUNT in the ble_bondmngr_cfg.h file. Not sure if that will work for you. It depends on how many CCCD's you have.
