Dear author,
why send Hermes::BoardAvailableData() by downstream or send MachineReadyData by upstream,it will close the connected?

void boardAvailable_data(void* ptrstream, void* ptrsink)
{
assert(ptrstream != nullptr);
assert(ptrsink != nullptr);
auto streamptr = (Hermes::Downstream*)ptrstream;
auto sinkptr = (Hermes::DownstreamSink*)ptrsink;
auto avd = Hermes::BoardAvailableData();
std::ostringstream oss;
oss << avd;
std::cout << oss.str();
streamptr->Signal(sinkptr->m_sessionId, avd);
}

void bachine_ready_data(void* ptrstream, void* ptrsink)
{
assert(ptrstream != nullptr);
assert(ptrsink != nullptr);
auto streamptr = (Hermes::Upstream*)ptrstream;
auto sinkptr = (Hermes::UpstreamSink*)ptrsink;
streamptr->Signal(sinkptr->m_sessionId, Hermes::MachineReadyData());
}
