First of all, I would like to say thank you for MySensors.
It seems to be doing all the things I expected for a longtime, and I have been trying to do it all by myself before...
So, I am new to MySensors, not to Arduino / ESP8266, etc...
I have been able to make a Gateway & a Sensor talk together.
I have been able to connect to my io.adafruit.com MQTT server, as well...
I am using the "void receive(MyMessage &msg)" routine to read incoming messages from my Sensor (a DHT22 based one).
But I cannot figure out how to get the data from it !
The variable I use doesn't seem to be a String, and I am pretty sure I coud get something like : MyNode = MyMessage.NODE_ID... but I can't find the explanation of how to read incoming messages...
Hint : I am a hardware engineer from 1985, and I developed my programming skills very late...
Here is the bit of code I use :
void receive(MyMessage &msg)
int MsgLen = MyMessage.length();
String Humid = MyMessage.substring(12, MsgLen);
The result is that MsgLen (Length of MyMessage) = 0. So to me this is not a String...
Thanks for your help,
