Glad it worked. Thanks for the update. You may also want to check that you are not calling sd_ble_gatts_sys_attr_set() as the peer manager is responsible for calling this function too.

Thank you Vidar.

This was the problem " You can also get this error if you are calling sd_ble_gap_sec_params_reply('BLE_GAP_SEC_STATUS_PAIRING_NOT_SUPP') from your application code outside of the peer manager module."

I am able to get the LESC pairing working now.

Thank you again,

Anil

Hi Anil,

The peer manager on the peripheral will return BLE_GAP_SEC_STATUS_PAIRING_NOT_SUPP if a pairing request is rejected as Einar mentions in this post: https://devzone.nordicsemi.com/f/nordic-q-a/37837/sdk15-paring-problem/145821#145821. You can also get this error if you are calling sd_ble_gap_sec_params_reply('BLE_GAP_SEC_STATUS_PAIRING_NOT_SUPP') from your application code outside of the peer manager module.

Regards,

Vidar

Hi Vidar,

I was able to build my application with LESC flag enabled (used GLS example) however I am still getting "Pairing not supported" error.

#define BLE_GAP_SEC_STATUS_PAIRING_NOT_SUPP 0x85 /**< Pairing not supported. */

I am using Nordic nRF52840 softdevice S132 peripheral.

My central device connects in LEGACY_ONLY mode however not with LESC_ONLY.

Any inputs are greatly appreciated.

regards,

Anil

Thank you Vidar, I am putting all the missing dependencies together for now and will late you know if further help is needed.

Thank you Jimmy for the suggestion.

As Jimmy suggested, it's best to start with an example that has LESC enabled by default. For instance, the ble_app_hrs example. There are quite a few crypto related dependencies you will have to add manually if you start with another project that don't include LESC.

1. Yes, the Softdevice supports it. Which chip are you using? I can make you a 's113' project for the ble_app_hrs example if it helps.

2. If you have enabled the LESC settings, then the linker errors are likely caused by missing dependencies.

I think you can refer to the HRM or HID example which has the LESC example.

It has the sdk_config.h to specify the LESC option.
