Socket Connection Demo Hangs on "H"

[flimshaw]

Hey there,

Thanks so much for your work on this. I'm getting the following message in my serial console when trying to run the demo, seems like it's connecting but then crashing shortly after? Log is as follows:

Connecting to ****
...
WiFi connected
IP address:
10.10.10.106
Connected
Waiting...

I have the same problem. I have narrowed it down to the analyserequest method in websocketserver.cpp. Once the header "upgrade: websocket" is recieved, serial.print prints out garbage. Im still digging.

Just ran into this myself too. I set the serial port rate down to 9600 and things are working for me. Turns out that even with broken serial output, the code was still running fine, i.e. I had the module sending strings to a websocket server on my computer and they were coming in.

Hi Mattfelsen, what code were you running on the server side? this the output which I am getting stuck at:
WiFi connected
IP address:
172.16.42.43
Connected
þ

There is no response after that. Any idea what may be going wrong?

Like Mattfelsen said, the program is still running, it just looks like it
isnt. I don't use the esp's serial output in my recent projects right now.
My esp is just responding to json commands by controlling other devices.
Still havent figured out why the serial is freezing though.

@deepikavira It was just a simple websocket echo server written with node.js and ws. Did you try changing the serial port baud rate (both in the code and in the Arduino IDE serial monitor window)?

[deepikavira]

@mattfelsen thanks for the quick response. I did reduce the baud rate to 9600 but still no luck with the serial monitor.
It now shows the following:
WiFi connected
IP address:
172.16.42.43
Connected

Anyway I think I will try giving it some functionality after the handshake and see if that works. @creation9 thanks for your quick response as well.

@deepikavira If you're having trouble with this library, there's another arduino websocket server/client lib for esp8226 here: https://github.com/Links2004/arduinoWebSockets I haven't tried it myself, but could be helpful if you're stuck

Was facing a similar problem..

// capture the value of analog 1, send it along
// pinMode(1, INPUT);
//data = String(analogRead(1));

data= "Hii";
webSocketClient.sendData(data);

Remove or comment-out the lines as shown above, put a string in 'data' variable and set the baud to 230400 and it works like charm..

Based on @sfa1906's findings, thought I'd share my experience with this issue.
Setting pinMode(1, INPUT); inside of the loop seems to be the problem here.
By moving it into setup I've managed to clear the issue.

jthiller, you are my savior
