send receive TEXT Virtuino6 VirtuinoCN - xmilav - 01-28-2024
Hello, I am doing a project with Arduino Mega2560 and Virtuino6 (version 6.0.34) communication via Bluetooth. I use Serial1 and the VirtuinoCN library.
I am interested in passing text strings from Virtuino6 to the Arduino, and from the Arduino to the Virtuino6.
Is it not supported?
I can't find any example.
Can someone show me an example?
Thank you.

Hi, this is an example for the Ethernet connection.
The only you have to do is to change the connection type lines.
https://virtuino.com/downloads/examples/virtuinoCM/Ethernet_ex3_send_receive_text.zip
On the top of the code declare two Strings:
String T0="";
String T1="";
On the void loop do something with the strings:
if (T0=="ENABLE PIN 5") digitalWrite(5,HIGH);
else if (T0=="DISABLE PIN 5") digitalWrite(5,LOW);
T1= "Hello Virtuino "+String(random(100));
Make these changes to the onReceived and onRequested methods
Code:
void onReceived(char variableType, uint8_t variableIndex, String valueAsText){
if (variableType=='V'){
float value = valueAsText.toFloat(); // convert the value to float. The valueAsText have to be numerical
if (variableIndex<V_memory_count) V[variableIndex]=value; // copy the received value to arduino V memory array
}
else if (variableType=='T'){
if (variableIndex==0) T0=valueAsText; // Store the text to the text variable T0
else if (variableIndex==1) T1=valueAsText; // Store the text to the text variable T1
//else if (variableIndex==2) T2=valueAsText; // Store the text to the text variable T2
//else if (variableIndex==3) T3=valueAsText; // Store the text to the text variable T3
}
}
String onRequested(char variableType, uint8_t variableIndex){ Code:
if (variableType=='V') {Code:
if (variableIndex<V_memory_count) return String(V[variableIndex]); // return the value of the arduino V memory arrayCode:
}Code:
else if (variableType=='T') {Code:
if (variableIndex==0) return T0; Code:
else if (variableIndex==1) return T1; Code:
//else if (variableIndex==2) return T2; Code:
//else if (variableIndex==3) return T3; Code:
}Code:
Code:
return "";Code:

Good evening Ilias, thank you for your prompt response.
I have already built a program with your comments but in the Virtuino6 APP, when selecting the memory in the "Test value display" field, the "T" option does not appear.
I attach screenshots of the mobile.
As I said, I use the Virtuino6 Pro 6.0.34 version.
Thanks for the help.
Xavier.

Hi, I sorry for the previous answer.
The T variable has been deprecated by Virtuino.
You can use the V variable for the text.
