C++: Fails to connect USB in streaming mode

[hexabyte23]

Hi All,

Not familiar with protobuf and Meshtastic packet, I try to send a request want_config_id to USB serial port streaming mode, but my Heltec Lora32 V3 is keeping protocol in plain text instead of Protobuf.

Any thoughts ?

void MeshtasticProtocol::encodeFrame(const  QByteArray &input, QByteArray &output)
{
   output.clear();
   output.append(START1);
   output.append(START2);
   output.append(input.size() / 256);  // MSB of protobuf length
   output.append(input.size() % 256);  // LSB of protobuf length
   output.append(input);
}

bool MeshtasticProtocol::sendPacket(const ::google::protobuf::MessageLite *packet)
{
   QByteArray input;
   input.resize(packet->ByteSizeLong());
   packet->SerializeToArray(input.data(), packet->ByteSizeLong());
   QByteArray output;
   encodeFrame(input, output);
   qint64 ret = port_->write(output);
   return (ret != -1);
}

void MeshtasticProtocol::requestWantConfigID()
{
   meshtastic::ToRadio packet;
   packet.set_want_config_id(0x10F2C); // request only my nodeinfo and skip other nodes in the db ?

   if(sendPacket(&packet))
      qDebug() << "meshtastic want_config_id sent";
}

Thanks,
Thierry
