Hi There
I am upgrading a project that runs for 2 years already
I am trying to add the reading of virtual pins from BLYNK app
This project ran on ESP8266 while adding BLYNK_WRITE command the compiler
creates the following error with the ARDUINO 1.8.12 and 1.8.13 version
b_global:180:59: error: variable or field ‘BlynkWidgetWrite1’ declared void
b_global:180:24: error: ‘BlynkReq’ was not declared in this scope
b_global:180:71: error: expected primary-expression before ‘const’
exit status 1
variable or field ‘BlynkWidgetWrite1’ declared void
I will appreciate your assistance - I am working on this bug for a long time now

// Blynk Dispaly App
char auth[] = "XXXXXXX";
//char ssid_B[] = "";
//char pass_B[] = "";
WidgetLED led20(V20); // Keep alive Blue Led
#define Blynk_KeepaLive_time 1 // define x sec interval to send keep-a-Live to
// This function will be called every time Slider Widget
// in Blynk app writes values to the Virtual Pin V1
BLYNK_WRITE(V1)
{
int pinValue = param.asInt(); // assigning incoming value from pin V1 to a variable
// process received value
}
void loop()
