I have problem with html code used with a server that used CC3000 wifi shield
the code inside loop is:
void loop(void)
{
// Try to get a client which is connected.
Adafruit_CC3000_ClientRef client = httpServer.available();
if (client) {
Serial.println(F(“Client connected.”));
// Process this request until it completes or times out.
// Note that this is explicitly limited to handling one request at a time!
// Clear the incoming data buffer and point to the beginning of it.
bufindex = 0;
memset(&buffer, 0, sizeof(buffer));
// Clear action and path strings.
memset(&action, 0, sizeof(action));
memset(&path, 0, sizeof(path));
// Set a timeout for reading all the incoming data.
unsigned long endtime = millis() + TIMEOUT_MS;
// Read all the incoming data until it can be parsed or the timeout expires.
bool parsed = false;
while (!parsed && (millis() < endtime) && (bufindex < BUFFER_SIZE)) {
if (client.available()) {
buffer[bufindex++] = client.read();
}
parsed = parseRequest(buffer, bufindex, action, path);
}
// Handle the request if it was parsed.
if (parsed) {
Serial.println(F(“Processing request”));
Serial.print(F(“Action: “)); Serial.println(action);
Serial.print(F(“Path: “)); Serial.println(path);
// Check the action to see if it was a GET request.
if (strcmp(action, “GET”) == 0) {
// Respond with the path that was accessed.
// First send the success response code.
client.fastrprintln(F(“HTTP/1.1 200 OK”));
// Then send a few headers to identify the type of data returned and that
// the connection will not be held open.
client.fastrprintln(F(“Content-Type: text/plain”));
client.fastrprintln(F(“Connection: close”));
client.fastrprintln(F(“Server: Adafruit CC3000”));
// Send an empty line to signal start of body.
client.fastrprintln(F(””));
// Now send the response data.
client.fastrprintln(F(“Hello world!”));
client.fastrprint(F(“You accessed path: “)); client.fastrprintln(path);
//nuovo codice
// now output HTML data starting with standart header
// client.println(“HTTP/1.1 200 OK”);
// client.println(“Content-Type: text/html”);
// client.println();
// client.print(“ARDUINO Controllo LED via WEB”);
//send first heading
client.println(“
LED CONTROL by internet connection
”);client.println(”
”);
client.println(“
LED control
”);//printing LED status
client.print(“LED status: “);
if (LEDON) {
client.println(“ON”);
}
else
{
client.println(“OFF”);
}
client.print(“
ACCENDI | SPEGNI
”);client.println(””);
readString=””;
//nuovo codice
}
else {
// Unsupported action, respond with an HTTP 405 method not allowed error.
client.fastrprintln(F(“HTTP/1.1 405 Method Not Allowed”));
client.fastrprintln(F(""));
}
}
// Wait a short period to make sure the response had time to send before
// the connection is closed (the CC3000 sends data asyncronously).
delay(100);
// Close the connection when done.
Serial.println(F(“Client disconnected”));
client.close();
}
}
// Return true if the buffer contains an HTTP request. Also returns the request
// path and action strings if the request was parsed. This does not attempt to
// parse any HTTP headers because there really isn’t enough memory to process
// them all.
// HTTP request looks like:
// [method] [path] [version] \r\n
// Header_key_1: Header_value_1 \r\n
// …
// Header_key_n: Header_value_n \r\n
// \r\n
bool parseRequest(uint8_t* buf, int bufSize, char* action, char* path) {
// Check if the request ends with \r\n to signal end of first line.
if (bufSize < 2)
return false;
if (buf[bufSize-2] == ‘\r’ && buf[bufSize-1] == ‘\n’) {
parseFirstLine((char*)buf, action, path);
return true;
}
return false;
}
// Parse the action and path from the first line of an HTTP request.
void parseFirstLine(char* line, char* action, char* path) {
// Parse first word up to whitespace as action.
char* lineaction = strtok(line, " ");
if (lineaction != NULL)
strncpy(action, lineaction, MAX_ACTION);
// Parse second word up to whitespace as path.
char* linepath = strtok(NULL, " ");
if (linepath != NULL)
strncpy(path, linepath, MAX_PATH);
}
// Tries to read the IP address and other connection details
bool displayConnectionDetails(void)
{
uint32_t ipAddress, netmask, gateway, dhcpserv, dnsserv;
if(!cc3000.getIPAddress(&ipAddress, &netmask, &gateway, &dhcpserv, &dnsserv))
{
Serial.println(F(“Unable to retrieve the IP Address!\r\n”));
return false;
}
else
{
Serial.print(F("\nIP Addr: “)); cc3000.printIPdotsRev(ipAddress);
Serial.print(F(”\nNetmask: “)); cc3000.printIPdotsRev(netmask);
Serial.print(F(”\nGateway: “)); cc3000.printIPdotsRev(gateway);
Serial.print(F(”\nDHCPsrv: “)); cc3000.printIPdotsRev(dhcpserv);
Serial.print(F(”\nDNSserv: ")); cc3000.printIPdotsRev(dnsserv);
Serial.println();
return true;
}
}
I can’t see the code in browser
client.println(“
LED CONTROL by internet connection
”);client.println("
");
client.println(“
LED control
”);//printing LED status
client.print("LED status: ");
if (LEDON) {
client.println(“ON”);
Where is the error? I tried fastrprint with F or not.
Thanks for help!!
