pc-ble-driver bonding sd_ble_gap_authenticate get error code 0x4 NRF_ERROR_NO_MEM

Question

Hi, I am trying to implement LESC Security Mode 1 Level 4 with a peripheral ble_app_hrs on PCA10040 and a central via pc-ble-driver example heart_rate_collector_v6 with PCA10059 . I am following MSC Bonding: Passkey Entry: User Inputs on Central My first step is to add sd_ble_gap_authenticate when BLE_GAP_EVT_CONNECTED comes. I have not yet implemented the full bonding sequences. However, the call of sd_ble_gap_authenticate returns with 0x4 * @retval ::NRF_ERROR_NO_MEM The maximum number of authentication procedures that can run in parallel for the given role is reached. I am running everything under Ubuntu 18.04. Peripheral ble_app_hrs is modified based on nRF5_SDK_15.2.0_9412b96 with a little change: //----------------------------------------------------------------------- //ble_srv_common.h /**@brief Security Access enumeration. * @details This enumeration gives the possible requirements for accessing a characteristic value. */ typedef enum { SEC_NO_ACCESS = 0, /**< Not possible to access. */ SEC_OPEN = 1, /**< Access open. */ SEC_JUST_WORKS = 2, /**< Access possible with 'Just Works' security at least. */ SEC_MITM = 3, /**< Access possible with 'MITM' security at least. */ SEC_SIGNED = 4, /**< Access possible with 'signed' security at least. */ SEC_SIGNED_MITM = 5, /**< Access possible with 'signed and MITM' security at least. */ SEC_LESC_MITM = 6 /**< SM1 Level4. */ }security_req_t; //----------------------------------------------------------------------- //ble_srv_common.c /**@brief Function for setting security requirements of a characteristic. * * @param[in] level required security level. * @param[out] p_perm Characteristic security requirements. * * @return encoded security level and security mode. */ static inline void set_security_req(security_req_t level, ble_gap_conn_sec_mode_t * p_perm) { BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS(p_perm); switch (level) { case SEC_NO_ACCESS: BLE_GAP_CONN_SEC_MODE_SET_NO_ACCESS(p_perm); break; case SEC_OPEN: BLE_GAP_CONN_SEC_MODE_SET_OPEN(p_perm); break; case SEC_JUST_WORKS: BLE_GAP_CONN_SEC_MODE_SET_ENC_NO_MITM(p_perm); break; case SEC_MITM: BLE_GAP_CONN_SEC_MODE_SET_ENC_WITH_MITM(p_perm); break; case SEC_SIGNED: BLE_GAP_CONN_SEC_MODE_SET_SIGNED_NO_MITM(p_perm); break; case SEC_SIGNED_MITM: BLE_GAP_CONN_SEC_MODE_SET_SIGNED_WITH_MITM(p_perm); break; case SEC_LESC_MITM: BLE_GAP_CONN_SEC_MODE_SET_LESC_ENC_WITH_MITM(p_perm); break; } return; } //----------------------------------------------------------------------- //ble_app_hrs peripheral main.c #define SEC_PARAM_BOND 1 /**< Perform bonding. */ #define SEC_PARAM_MITM 1 /**< Man In The Middle protection not required. */ #define SEC_PARAM_LESC 1 /**< LE Secure Connections enabled. */ #define SEC_PARAM_KEYPRESS 0 /**< Keypress notifications not enabled. */ #define SEC_PARAM_IO_CAPABILITIES BLE_GAP_IO_CAPS_DISPLAY_ONLY /**< Display Only. */ #define SEC_PARAM_OOB 0 /**< Out Of Band data not available. */ #define SEC_PARAM_MIN_KEY_SIZE 7 /**< Minimum encryption key size. */ #define SEC_PARAM_MAX_KEY_SIZE 16 /**< Maximum encryption key size. */ //...... // Here the sec level for the Heart Rate Service can be changed/increased. hrs_init.hrm_cccd_wr_sec = SEC_LESC_MITM; hrs_init.bsl_rd_sec = SEC_LESC_MITM; Central pc-ble-driver example is modified based on "2019-03-06 08:55 Ken A.

Thanks and best regards! Chencheng

I managed to get sd_ble_gap_authenticate() to succeed with sd_api_v6 and your example. I simply set ble_cfg.gap_cfg.role_count_cfg.central_sec_count equal to 1 in examples\heart_rate_collector\main.c in the function ble_cfg_set(..) . Then I got: "sd_ble_gap_authenticate succeeded". 
 Best regards, 
 Simon
