I used ble_app_hrs Demo to test bonding. However, I have been unable to bpnd successfully. I'll give you my bonding parameters.
#define SEC_PARAM_BOND 1
#define SEC_PARAM_MITM 1
#define SEC_PARAM_LESC 1
#define SEC_PARAM_KEYPRESS 0
#define SEC_PARAM_IO_CAPABILITIES BLE_GAP_IO_CAPS_KEYBOARD_DISPLAY
#define SEC_PARAM_OOB 0
#define SEC_PARAM_MIN_KEY_SIZE 7
#define SEC_PARAM_MAX_KEY_SIZE 16
static void peer_manager_init(void)
{
ble_gap_sec_params_t sec_param;
ret_code_t err_code;
err_code = pm_init();
APP_ERROR_CHECK(err_code);
memset(&sec_param, 0, sizeof(ble_gap_sec_params_t));
// Security parameters to be used for all security procedures.
sec_param.bond = SEC_PARAM_BOND;
sec_param.mitm = SEC_PARAM_MITM;
sec_param.lesc = SEC_PARAM_LESC;
sec_param.keypress = SEC_PARAM_KEYPRESS;
sec_param.io_caps = SEC_PARAM_IO_CAPABILITIES;
sec_param.oob = SEC_PARAM_OOB;
sec_param.min_key_size = SEC_PARAM_MIN_KEY_SIZE;
sec_param.max_key_size = SEC_PARAM_MAX_KEY_SIZE;
sec_param.kdist_own.enc = 1;
sec_param.kdist_own.id = 1;
sec_param.kdist_peer.enc = 1;
sec_param.kdist_peer.id = 1;
err_code = pm_sec_params_set(&sec_param);
APP_ERROR_CHECK(err_code);
err_code = pm_register(pm_evt_handler);
APP_ERROR_CHECK(err_code);
}
At the same time, I use another device, can bind successfully. The parameters are the same.
