Can only access 2 bytes of data during BLE_GATTS_EVT_RW_AUTHORIZE_REQUEST

[Bloq]

Hello,

I am using nrf52840 and sdk15.  I have enabled read and write authentication and am having trouble accessing all of the data from p_ble_evt->evt.gatts_evt.params.authorize_request.request.write.data.  Similarly the len value seems to always be 2.  Lastly, am also trying to write 32 bytes, is this possible in one write?  Below is the characteristic configuration.

static uint32_t security_char_add(status_serv_t * p_status_serv)
{
    ble_add_char_params_t add_char_params;

    VERIFY_PARAM_NOT_NULL(p_status_serv);

    memset(&add_char_params, 0, sizeof(add_char_params));

    add_char_params.uuid                = SECURITY_UUID;
    add_char_params.uuid_type           = 0;
    add_char_params.max_len             = 32;
    add_char_params.char_props.read     = 1;
    add_char_params.char_props.write    = 1;
    add_char_params.read_access         = SEC_JUST_WORKS;
    add_char_params.write_access        = SEC_JUST_WORKS;
    add_char_params.is_defered_read = 1;
    add_char_params.is_defered_write = 1;

    return characteristic_add(p_status_serv->service_handle, &add_char_params, &p_status_serv->security_handles);
}

Thanks in advanced,

Are you sure it is the same write request on the characteristic you are interested in? Does the peer actually send a write request with 32 bytes length?
