Gopro wifi control with Arduino

Projects Discussion and Showcase Device Hacking

Hi all, I'm hoping someone has played with this before but perhaps i'm the first.

I have a GoPro HD2 camera with WiFi attachment - It acts as a wireless access point.

I have paired with this, a wireless AP in Client mode - i.e it's acting like a computer connecting to the camera but connects to the network so i can access it via any 'pc' on the network.

The camera is controlled via HTTP GET requests in the form of http:///bacpac/PW?t=&p=%01

I can jump on my PC and enter the string above into a browser and it turns the camera on - Beatutiful i think!

I created an arduino sketch to connect to the camera and turn it on:

#include <SPI.h>
#include <Ethernet.h>

byte mac[] = {  0x00, 0x28, 0x8B, 0x62, 0xC9, 0xED };
byte ip[] = { 10, 5, 5, 110 }; 
IPAddress server(10,5,5,9); // GoPro

// constants won't change. They're used here to 
// set pin numbers:
const int sensorpin = 18;     // the number of the pushbutton pin
const int ledPin =  2;      // the number of the LED pin
const int solenoid = 3;
boolean movement = 0;

EthernetClient client;

void setup() {
  
   Serial.begin(9600);
  // start the Ethernet connection:
  Serial.println("Starting Network");
  if (Ethernet.begin(mac) == 0) {
    Serial.println("Failed to configure Ethernet using DHCP");
    // no point in carrying on, so do nothing forevermore:
    for(;;)
      ;
  }
  
//  Ethernet.begin(mac,ip);
  
  delay(1000);
  Serial.println("Connecting to GoPro");
  // Try to get the status of the gopro
  if (client.connect(server, 80)) {
    Serial.println("connected");
    // Make a HTTP request:
    Serial.println("Powering on GoPro");
    client.println("GET /bacpac/PW?t=blahblah&p=%01 HTTP/1.0");
    client.println();
  } 
  else {
    // if you didn't get a connection to the server:
    Serial.println("connection failed");
  } 
  // initialize the LED pin as an output:
  pinMode(ledPin, OUTPUT);      
  pinMode(solenoid, OUTPUT);
  digitalWrite(ledPin, HIGH);
  digitalWrite(solenoid, HIGH);
  
  // initialize the pushbutton pin as an input:
  pinMode(sensorpin, INPUT);    
  digitalWrite(sensorpin, LOW); 
}

but it bombs out at the client.connect line i.e can't even open port 80 as if there is no IP or there is no physical connection but from the PC i can ping the Arduino and the camera fine.

I know this is a very specific thing and i'm probably strugling for someone to have an answer off the bat but has anyone tried anything like this before?

here is mine.....

using wifi module + digilent duino. (sorry, cant find my mini arduino boards :smiley: :smiley: :smiley: )
ill try your code once i find my tplink running openwrt.

thanks to the guys here: Howto Livestream to PC and view files on PC/Smartphone! - Page 16 - GoPro Forum
saves me time sniffing on gopro's iOS and android official apps....

i tested your code with arduino + ethernet shield with tplink wifi client router connected to gopro. and it worked without issue. here is the test video:

here are some photos of my diy arduino board with ethernet shield on a case

and here is the actual code i used in the video

#include <SPI.h>
#include <Ethernet.h>

byte mac[] = {  0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED };
IPAddress server(10,5,5,9);

EthernetClient client;

void setup() {
  Serial.begin(9600);
  if (Ethernet.begin(mac) == 0) {
    Serial.println("Failed to configure Ethernet using DHCP");
    for(;;)
      ;
  }
  delay(1000);
  Serial.println("Connecting...");

  if (client.connect(server, 80)) {
    Serial.println("Photo mode:");
    client.println("GET /camera/CM?t=<goprohero>&p=%01 HTTP/1.0");
    client.println();
  } 
  else {
    Serial.println("Connection failed");
  }
}

void loop()
{
  if (!client.connected()) {
    Serial.println();
    Serial.println("Connection lost!.");
    client.stop();
    for(;;)
      ;
  } else {
    if (!digitalRead(5)){
      Serial.println("Click!");
      client.println("GET /bacpac/SH?t=<goprohero>&p=%01 HTTP/1.0");
      client.println();
      delay(500);
    }
  }
}

cool!
I can connect simultaneously to 5 gopro?
using a single wireless card
