In sdk9.0 s130,I want to pairing with phone,I have changed sec_param,but in the phone not display the entry passkey window.

[lifangcheng]

this is my sec_param:

sec_param_bond   1
sec_param_mitm   1
sec_param_io_capabilities   ble_gap_io_display_only
sec_param_oob        0
sec_param_min_key_size     7
sec_param_max_key_size     16
passkey_length    6
static passkey   123456

this is on_ble_peripheral_evt:

case ..
case ble_gap_evt_sec_params_requset:
sec_param.bond  = 1
sec_param.mitm  = 1
sec_param.io_capabilities =  ble_gap_io_display_only
sec_param.oob     =  0
sec_param_min_key_size  =   7
sec_param_max_key_size   =  16
sec_param.kdist_periph.enc=1;
sec_param.kdist_periph.id=1;
err_code=sd_ble_gap_sec_params_reply(m_conn_handle_peripheral,ble_gap_sec_status_success,&sec_params,NULL);
APP_ERROR_CHECK(err_code);
case ..

Do any of your characteristics need authentication/encryption to be read?

This is normally what trigger the central device (phone) to send a pairing request.

You can have a look at rx_char_add() here.

Specifically:

BLE_GAP_CONN_SEC_MODE_SET_ENC_WITH_MITM(&attr_md.read_perm);
BLE_GAP_CONN_SEC_MODE_SET_ENC_WITH_MITM(&attr_md.write_perm);
