How To Add AES128 bit encription in my Application

[Murugan]

Dear Nordic Team,

Thanks for supporting.

I want support for AES18bit Encription. Need basic tutorials and how to add my existing code.

Hi Murugan, 

 Decimal 4352 is 0x1100. The following defines and reasoning for this error in peer_manager_types.h:

#define PM_CONN_SEC_ERROR_BASE 0x1000  /**< @brief The base for Peer Manager defined errors. See @ref PM_SEC_ERRORS and @ref pm_sec_error_code_t. */
#define PM_CONN_SEC_ERROR_DISCONNECT         (PM_CONN_SEC_ERROR_BASE + 0x100) /**< @brief Pairing or encryption did not finish before the link disconnected for an unrelated reason. */

So it looks like the device disconnects before the pairing or encryption procedure completed.

Can you provide the full log output from the failing device? If you could set NRF_LOG_DEFAULT_LEVEL to 4 in your sdk_config.h file, that should provide more details.

What device are you testing against?

Can you provide a sniffer trace between the two devices when trying to perform bonding? You can use nRFSniffer v2 for that.

This thread might help.
