### __Zum aktivieren von GDBStub:__
```c
#include <GDBStub.h>

...

void setup() {
  Serial.begin(460800);
  gdbstub_init();
```

### __Achtung !__
GDB muss dafür compiled werden
GDB-Version aus Arduino Toolchain hat Support

```sh
$ ./start_xtensa_gdb_stub.sh
```

### __Achtung !__
Don`t forget __\r__

ESP-OTA wird von ufw oder Defender geblockt.
- Windows -> Python needs to be granted with rights
- Linux -> open udp port in ufw -> 

```sh
platform.ini 
upload_flags =
  --host-port <PORT>
...
$ sudo ufw allow tcp/<PORT>
```


```c++
server.streamFile(f, mime::getContentType(SRH::_path), requestMethod);

=====>

const String& p = SRH::_path;
if(p.endsWith(".gzip")) {
    server.sendHeader("Content-Encoding", "gzip");
    server.streamFile(f, mime::getContentType(p.substring(0, p.length()-5)), requestMethod);
}
else
    server.streamFile(f, mime::getContentType(SRH::_path), requestMethod);
```


Webserver on v0.3.0 now working with LittleFS
TODO:
- check dir for files automatic
- move handleNotFound to httpserver.h
- maybe compress files ?
