QUESTION

How to keep WebSocket connection Alive - Flutter AWS?

Asked 2021-Oct-21 at 14:32

I am trying to connect to a Websocket API hosted in AWS from my Flutter app.
I am using the web_socket_channel package to build a real-time tchat app.

I have different routes for my WebSocket API : $connect, $disconnect and sendMessage. I would like to send events to the server and get responses in dart.

So far, i have no way to debug this as the web_socket_channel doesn't offer this possibility... So i am simply not receiving events nor sending them (no logs in my CloudWatch log group, whereas i have some using wscat or Postman tool that are both working fine).

Here is my code :

When the data is received the connection is closed. Just reconnect the server onDone and/or onError.

How to change libwebsockets color scheme

Asked 2021-Sep-01 at 01:32

I am using libwebsockets library. This exposes certain methods for writing into a log file. lwsl_warn(...), lwsl_err(...) and lwsl_err(...) to name the most common. The output is color coded using ANSI sequences.

Is there a way to set the default color scheme (other than recompiling the library)? Thanks.

I poked around in the libwebsockets source and found my answer: The colors are hard coded - so the answer to my original question is "no".

However, the color scheme is not hard to find and edit. It resides in two source files - one of these is compiled depending on options:

At the end of the publish() function the if statement is missing enclosing braces so it doesn't do what you think it does.

Something is wrong with your ARM toolchain or how the build system uses it. Where did you get it from and how did you install it?

The header sys/capability.h is included with the ARM toolchain. For example, when I install the Debian package gcc-arm-linux-gnueabihf then this header file gets copied to /usr/arm-linux-gnueabihf/include/linux/capability.h. The toolchain is supposed to find it there on its own.

The command arm-linux-gnueabihf-gcc -v will show you where the toolchain is configured to look for its own header files. E.g. in output below it's --includedir=/usr/arm-linux-gnueabihf/include that matters, the header should be found relative to this directory. I apologize for the super long line.
