Hey guys, I had a working code running in my Spark Core. The compile-server2 changes where rolled out and re flashed my spark core to change the brightness and update the I2C address of my LCD. However, the TCP Client stopped working, I’m not able to read any returned http post or get. I have trie…

I have the same problem, my code stopped working. See my other thread: [image] TCPClient.available() does not return length Firmware look at the following example: https://gist.github.com/synox/b049a88bb533d7c3ec4c it works w…

I have this feeling with the auto escaping of strings. … something is broken within strings even though they compile. Can you try to monitor the request from the server side somehow and see if it it getting there, and if so if it’s botched at all? Or spit your strings out on Serial to see what they…

Ok guys, looks like the compiler is stripping out single backslashes from strings. EXAMPLE CODE: void setup() { pinMode(D7,OUTPUT); digitalWrite(D7,HIGH); Serial.begin(9600); while(!Serial.available()); } void loop() { Serial.println("HTTP/1.0 pass"); Serial.println("http:…

Thanks @BDub for distilling this

No problem, only thing is I don’t think @Iv4n 's code has any important uses of backslash that might make it fail. One thing I would do @Iv4n instead of client.read(); is something like this: // wait 5 seconds or less for the server to respond uint32_t startTime = millis(); while(!client.available…

I am also having trouble that started tonight (before 2014-01-28T00:17:52-05:00). My problem is not directly related to backslash, but to other quoted chars. I have been successfully parsing an html string that is structured as field=“value” and my parser is suddenly failing. I think this is rela…

I replaced my web page parser with just: void serialEvent() { char inChar = myTCP.read(); Serial.print(inChar); } In my loop(), I do: while (myTCP.available()) { serialEvent(); } And I do not see the full contents of the web page like I used to. The first 604 chars are completely missi…

I’m also seeing issues with TCP Client reads… if anyone can run this example and tell me what I’m doing wrong I’d appreciate it. I’m basically missing chunks of data, and I’m waiting plenty of time to get further chunks from the server. I’ve even increased the timeout in http_get() to 5 seconds an…

There is another thread where there is similar discussion and a patch to TCPClient that has fixed the problem for some. I don’t have time to test this myself, but I thought you would want to know. I hope that @zachary can get this fix applied quickly–I am dead in the water right now.

That’s great guys, thanks a lot for the fast feedback and workarounds, in my case I was able to fix the code looping until available() returned something: String http_get(char const* hostname, String path) { if (client.connect(hostname, 80)) { client.print("GET "); clie…
