Did you guy manage a solution for this problem?

Thanks

Mistake by me i always have bad request event if temp is more the 1 degree, If i put it manually like this everything is find and update:

Code:

ether.browseUrl(PSTR("/data_request?id=variableset&DeviceNum=48&serviceId=urn:upnp-org:serviceId:TemperatureSensor1&Variable=CurrentTemperature&Value=7"), "", website, my_callback);

How the do i include the temerature after the=

Maybe that when it convert the 0 in the first bytes, bytes is null? Could that be my problem and if so could a byte be 0 not null.

If value of the sensor is more then 1 , data is send to the server and i receive a ok message. as soon as the temperature is 0, i receive a bad request error 400.

Really dont understand your answer

Hi again,
             could it be possible that when temperature is start with 0, it unable to send the url it give me a error?

Code:

if ((timing ==1) && (millis() > timer)) {
    timer = millis() + 5000;
    sensors.requestTemperatures();
    Serial.println();
    Serial.println("<<< REQ ");
    float sensor1 = (sensors.getTempCByIndex(1));
    char buffer[10];
    dtostrf(sensor1, 5, 2, buffer);
    Serial.println("Sensor2 temperature is:");
    Serial.println(buffer);
    timing = 0;
    delay(500);
    ether.browseUrl(PSTR("/data_request?id=variableset&DeviceNum=48&serviceId=urn:upnp-org:serviceId:TemperatureSensor1&Variable=CurrentTemperature&Value="), buffer, website, my_callback);
   

Thanks,
           yes it will help. could you tell me how to read it after that.

got it thanks

Code:

  ether.packetLoop(ether.packetReceive());
  if (millis() > timer) {
    timer = millis() + 5000;
    sensors.requestTemperatures();
    Serial.println();
    Serial.println("<<< REQ ");
    float sensor1 = (sensors.getTempCByIndex(0));
    char buffer[10];
    dtostrf(sensor1, 5, 2, buffer);
    Serial.println(buffer);
    delay(500);
    ether.browseUrl(PSTR("/data_request?id=variableset&DeviceNum=38&serviceId=urn:upnp-org:serviceId:TemperatureSensor1&Variable=CurrentTemperature&Value="), buffer, website, my_callback);

I need to put a delay before sending the url cause it was giving me sometime some bad number.

Hi again,
             i finally got my sketche working with the enc28j60. Now i'm able to send to my domotic box the temperature of a one-wire sensor. The only problem that i have is it dont take in concideration the . and the to number next to it so if temperature is 21.56 only 21 will be sent.
Here the code:

Code:

void loop () {
  ether.packetLoop(ether.packetReceive());
  if (millis() > timer) {
    timer = millis() + 10000;
    sensors.requestTemperatures();
    Serial.println(sensors.getTempCByIndex(0));
    Serial.println();
    Serial.println("<<< REQ ");
    char myIntAsString[24]; // 7 bytes is enough to contain any int, including minus sign and terminating zero
    itoa((sensors.getTempCByIndex(0)), myIntAsString, 10);
    Serial.print(myIntAsString);
    ether.browseUrl(PSTR("/data_request?id=variableset&DeviceNum=38&serviceId=urn:upnp-org:serviceId:TemperatureSensor1&Variable=CurrentTemperature&Value="), myIntAsString, website, my_callback);
}
}

Here the result in the serial print:

Code:

P:  192.168.2.124
GW:  192.168.2.1
DNS: 192.168.2.1
SRV: 192.168.2.19
19.25

<<< REQ
19>>>
HTTP/1.1 200 OK
content-Type: text

...

So before convert it to a compatible const char*, sensor read 19.25, but it send 19.

Any idea
Thanks

 

Thanks,
           i try what you say and now i'm able to compile it without error.
The problem now is that it give me a bad request. If i print the temp, it give me the temperature. If i replace the temp with "88", no error occur and value 88 is updated. I'm lost

Try with int and float, same problem, ethercard seems to need a const char* in the formule: ether.browseUrl(PSTR.....
How could i declare a const char* that could be variable.

Thanks in advance

Hi all,

        My problem is i want to put a variable for the temperature but i have an error: error: invalid conversion from 'char' to 'const char'
 here the code:

Code:

// Demo using DHCP and DNS to perform a web client request.
// 2011-06-08 <jc@wippler.nl> http://opensource.org/licenses/mit-license.php

#include <EtherCard.h>

// ethernet interface mac address, must be unique on the LAN
static byte mymac[] = { 0x74,0x69,0x69,0x2D,0x30,0x31 };

byte Ethernet::buffer[700];
static uint32_t timer;

char website[] PROGMEM = "192.168.2.19";
static byte hisip[] = {192,168,2,19};
char temperature;

// called when the client request is complete
static void my_callback (byte status, word off, word len) {
  Serial.println(">>>");
  Ethernet::buffer[off+300] = 0;
  Serial.print((const char*) Ethernet::buffer + off);
  Serial.println("...");
}

void setup () {
  Serial.begin(57600);
  Serial.println("\n[webClient]");

  if (ether.begin(sizeof Ethernet::buffer, mymac, 10) == 0)
    Serial.println( "Failed to access Ethernet controller");
  if (!ether.dhcpSetup())
    Serial.println("DHCP failed");

  ether.printIp("IP:  ", ether.myip);
  ether.printIp("GW:  ", ether.gwip); 
  ether.printIp("DNS: ", ether.dnsip); 
  ether.copyIp(ether.hisip, hisip);
  ether.hisport = 3480;
  ether.printIp("SRV: ", ether.hisip);

  if (!ether.dnsLookup(website))
    Serial.println("DNS failed");
}

void loop () {
  ether.packetLoop(ether.packetReceive());
 
  if (millis() > timer) {
    timer = millis() + 10000;
    temperature = 77;
    Serial.println();
    Serial.print("<<< REQ ");
    ether.browseUrl(PSTR("/data_request?id=variableset&DeviceNum=49&serviceId=urn:upnp-org:serviceId:TemperatureSensor1&Variable=CurrentTemperature&Value="), temperature, website, my_callback);
}
}

Ok other method, let say i want to insert value in the url:

Code:

ether.browseUrl(PSTR("/data_request?id=action&DeviceNum=(((HERE))&serviceId=urn:upnp-org:serviceId:SwitchPower1&action=SetTarget&newTargetValue="), "1", website, my_callback);

In python i use the s% function like this:

Code:

"/data_request?id=action&DeviceNum=%s&serviceId=urn:upnp-org:serviceId:SwitchPower1&action=SetTarget&newTargetValue=" $ devid

but is there a way in arduino code
thanks

Normally to call it i use String not string, if i put string, it say that i have not  declare it.

maybe it late here but i don't understand what you means?
Sorry
