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 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…

@BDub not really answering but having a problem using your code. I set up a web service that queries http://openweathermap.org/ and then maps temperature and conditions to RGB codes (I want to create a moodlight based on the weather.) the web service url is: http://roman-mueller.ch/api/weather As…

Hey Guys, Popping in to say I fixed some issues with the pre-processor stripping out stuff it shouldn’t. I’ve changed the approach it takes, so that shouldn’t be a side-effect anymore. Please keep sending me any code you find that doesn’t compile like you think it should, and we’ll add unit tests…

I just want to report back a minor success. Remember in the early days we all noticed that TCPClient.available() was returning a boolean rather than a count of bytes? Well the recent changes fixed this and it must be related to the TCPClient problems. My old code for the boolean case looked like …

Thanks @bko for the report! Here are the commits for the recent changes to TCPClient: Wiring TCPClient Bug Fix - updated available() and read() methods committed 11:09AM - 21 Jan 14 UTC (UTC) [satishgn] …

What does serialEvent() do? If you let it fall through your loop() over and over again, how do you know when you are done with the transfer?

Yeah I don't know why everyone is messing around with TCP Clients right when it's currently broken, but it's popping up a lot today! See my post and a temporary fix by weakset here:
