Need Help with the Iduino Yun Shield on a Mega2560

Post by charcuterie » Sun Sep 18, 2016 10:04 am

Hi, I am new to Arduino but I have managed to get my board to run a temp/humidity sensor and upload the data to thingspeak via ethernet cable.

I now want to do this via wifi so I dont need the connected ethernet cable.

I have an Arduino Mega 2560 board and have placed the Iduino Yun shield V1.2 onto it,

I have been able to connect directly (Laptop<->iduino yun shield) via wifi to the shield and set it up and then reconnect via my home wifi network (Laptop<->wifi network WPA2<->iduino yun shield), this all seems to be working fine.

I have placed the jumper on the mega16u2 bridge mode reset pins on the Arduino mega 2560 board (though 1 site says you dont need to do that now)

I have uploaded sketches both directly from the arduino IDE and have also tried via hex file upload via the iduino yun shield settings page)

I have updated the Geeetech Iduino Yun shield (v1.2) to the dragino firmware V 2.0.7 (one site suggested this will help)

I initially had troubles updating the board.txt file but a great text editor called Boards.txt helped sort that out

I have added and tried both these settings for dragino and arduino in the board.txt file

Now I am able to upload this following sketch..................................


#include <Console.h> //use Console class for Arduino IDE debug over WiFi, similar to Serial class,
String name;

void setup() {
// Initialize Console and wait for port to open:
Bridge.begin();
Console.begin();

// Wait for Console port to connect
while (!Console);

Console.println("Hi, what's your name?"); //Data flow: Arduino --> Yun Shield --> Arduino IDE
}

void loop() {
if (Console.available() > 0) {
char c = Console.read(); //read the next char received, data flow: IDE --> Yun Shield--> Arduino
// look for the newline character, this is the last character in the string
if (c == '\n') {
//print text with the name received
Console.print("Hi ");
Console.print(name);
Console.println("! Nice to meet you!");
Console.println();
// Ask again for name and clear the old name
Console.println("Hi, what's your name?");
name = ""; // clear the name string
}
else { // if the buffer is empty Console.read() returns -1
name += c; // append the read char from Console to the name string
}
}
}



But when I open the serial monitor in the arduino V1.6.11 IDE is dosnt connect and says is the sketch using the bridge?

I suspect there is a problem either with my sketch or the bridge or some uploading issue of the sketch, though it appears to upload correctly.

there is a section talking about bridge issues and sketch upload issues on this webpage but it seems very technical to me
http://www.geeetech.com/wiki/index.php/ ... Yun_Shield


I have spent 3 days trying to make this work, I have scoured the forums but I now submit to needing some help with this. As I mentioned I am new to this technology and I am sure I am missing something simple.

Thanks for the reply,

I have spent 3 days going over the manual, I seem to be able to upload the sketch via the arduino IDE but if I upload a HEX version from within the idunino yun shield i get

Uploading sketch...
Bootloader stk500v2/stk500boot_v2_mega2560.hex will be added to the sketch
Previously running Bridge terminated.
Error while running avrdude

avrdude: AVR device not responding
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.


When I have uploaded a sketch via the arduino IDE and open the serial monitor I get
Unable to connect...retrying
.....
....
Unable to connect : is the sketch using the bridge?

What should I try next???

Thanks for that last link William Kwok,

I needed the 5V jumper, i initially placed it as per your diagram in the link but it didnt work so I tried the other jumper setting and it worked but when i looked at the board under a magnifying glass the 5V was the correct setting just back to front from the diagram.

Once again thankyou very much

yun shield is not stable. i have same issues with some shield.. ethernet port shutdown... unconnected uno board.. depending of shield..
anyway with the v1.1 and firmware 2.07 i had better issue
you should use the new board list : http://www.dragino.com/downloads/downlo ... index.json
with any uno/mega without jumper
in your sketch use

#include <Bridge.h>

setup
Bridge.begin();
Console.begin();

Console.print("blabla"); to see result in serial monitor

do not use pins 10/11/12/13 for other purpose and RX/TX as weel to maintain connection between uno and yu shield
hope this can help
