Whatttt!! How about using 4.2RC1? I think there was a GC bug in 4.1 from what I've read. #17026 Problem With Basic Project
Hmm haven't checked mine in days until now and it still works  I'm running 4.2RC1 all around. The only difference I can think of is I'm using a static ip, are you?
#16842 Problem With Basic Project
You got it! And yeah it's been running for days
#16824 Network Resetting Issue
I'm no expert, I'm just starting to learn too, but I think it's because you only have one thread and you are blocking it for 5 seconds at a time. Try this: main() { while(true) { int i = 0; } } #16801 Problem With Basic Project

#16800 Network Resetting Issue
Can you post the code you are using? #16728 Problem With Basic Project
The download for the manual is at: http://www.lg.com/co...ategoryIdCms=3#
I *think* I can just use it as it, I will probably buy a break out if I can instead of a shield. If you see at the END, there is R232 stuff, and one it with a 3 pin connection...
#16724 Problem With Basic Project
I was only sending it a VERY small amount of data so I don't think applies. But I did switch to a threaded model and it fixed my issue. I don't think anyone will know this, but my LG tv can use only 3 pins in RS232 (RX, TX, and GRND) and it says it is UART, can I just use pins d0 + d1 as com1 and go right in without a shield? #16716 Problem With Basic Project
No luck. I took it out of the constructor and I get the same results. It fails 3/4 times or so, it just does not give back a response. I'd like to fix this before continuing forward with my project. #16712 Problem With Basic Project
I will try that! I think that was from the example code. Just some other notes, it fails only about 1 out of 10 times when I have it attached to the debugger and I am using a static IP. #16698 Problem With Basic Project
I used code that was in an example and modified it some to do some tests. It's just a basic web server. Well id say 2/3 requests I sent get back a 503 error. I've attached the code, it doesn't make sense to me. I tried changing to 4.2 as well and that did not fix it:
