B4R Question Callback from Inline C to B4R Sub with parms

[KMatle]

I try to pass the two variables from Inline C (without using global variables): from and &msg to a sub in B4R giving

b4r_main.cpp:85:35: error: no matching function for call to 'b4r_main::_newmessage(uint32_t&, String*)'

void receivedCallback( uint32_t from, String &msg ) {
  Serial.printf("Received from %u msg=%s\n", from, msg.c_str());
  b4r_main::_newmessage(from, &msg);
}

Sub newmessage(node As ULong, m As String)
    Log(node,"->",m)
End Sub

The second one seems to be a String pointer. Can someone give me a hint here?

B4RString is no the same thing as String. Check this code: https://www.b4x.com/android/forum/threads/how-to-convert-string-to-b4rstring.138236/post-875169
