Bridge causes error message

Solved

Hi there
I´m trying to change my code from a Yun board to a wemos d1 mini.

It´s a simple bridge example that performs well using Yun.
But when I compile it using the d1 Board I get this error message:
xtensa-lx106-elf-gcc: error: libraries\Bridge\Bridge.a: No such file or directory

Any idea?

My code:

/**************************************************************
  Detects the status of Garage door by RED switch and
  send´s it to:
  ~ TOR_Receiver which will blink the BUILTIN_LED when door is open
  ~ Blynk APP Tor_Status Value V11
  ~ Blynk APP Tor_Status LED

#define BLYNK_PRINT Serial    // Comment this out to disable prints and save space
#include <Bridge.h>
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
#include <MY_WiFi.h> // MY_personal WiFi credentials
#define MY_switch D1

char auth[] = "xxxxxxxx"; //Tor-Status-ESP-D5EFEB
WidgetBridge bridge1(V1); // Bridge widget on virtual pin 1


void setup()
{ pinMode(BUILTIN_LED, OUTPUT);  // initialize onboard LED as output BUILTIN_LED=D4
  pinMode(MY_switch, INPUT_PULLUP);
  delay (1000);
  Serial.begin(9600);
  Blynk.begin(auth, ssid, pass);

  interrupts();
  //********************************************************
}


BLYNK_CONNECTED() {
  bridge1.setAuthToken("yyyyyyy"); // Place the AuthToken of the second hardware here  Tor-Receiver-ESP-D5F066
}

void loop()
{
  Blynk.run();

  if (digitalRead(MY_switch) == HIGH)
  {
    Serial.println("HIGH");
    bridge1.digitalWrite(4, HIGH);  // Digital Pin 9 on the second board will be set HIGH
    bridge1.virtualWrite(V5, 1); // Sends 1 value to BLYNK_WRITE(V5) handler on receiving side.
    Serial.println(F("write HIGH"));
  }
  else
  {
    Serial.println("LOW");
    bridge1.digitalWrite(4, LOW); // Digital Pin 9 on the second board will be set LOW
    bridge1.virtualWrite(V5, 0); // Sends 0 value to BLYNK_WRITE(V5) handler on receiving side.
    Serial.println(F("write LOW"));
  }
}

BLYNK_WRITE(V5) {  //This is only for example to demonstrate the board is still running
  int pinData = (param.asInt() * 255); // pinData variable
  digitalWrite(BUILTIN_LED, pinData);
}

void timer0_ISR (void) //this is for example only change it to your ISR needs
{
  digitalWrite( BUILTIN_LED, digitalRead( BUILTIN_LED ) ^ 1 ); // blink 1/sec
  timer0_write(ESP.getCycleCount() + 80000000L); // 80MHz == 1sec

}

May be I found it my self.
the include bridge.h is not present within the actual example of bridge
I deleted it in my sketch and could compile with out error message.

I hope that it will now work without the include ???

Where did you get the bridge.h file? It’s not part of the Blynk lib nor is it required.

4

Bridge.h is for Yun only, it is not part of Blynk Library and it is not related to Bridge Widget

5

I do not remember where it is from.
I used the blynk examples to perform my first steps together with Yun and blynk.

@vshymanskyy
Sorry but I have to correct you.
But it is provided together with blynk.
When I load the < example < blynk < boards_wifi < Arduino_yun
It will load the sketch like below
and bridge.h is included.

@Brummer sorry but you’re wrong ))) … so don’t correct me this time.

@brummer, hopefully our online example browser will help you to mix examples together

@Brummer Bridge.h is a standard Arduino library that just happens to be used by the Yun but it has no relation to Blynk’s Bridge widget.

@Costas,
thank you for your clarification.
@vshymanskyy
sorry for my mistake, because it has been provided together with the yun blynk example I assumed that it uses to blynk.

Yes, but it is really needed on Yun, but not for Blynk Bridge. Glad you got the idea…
