Android Question Network library

[Hakanunver]

Hii
We use On Android Network library for TCP/IP connections. Special device connect our android app and sended data , Our Android app if receive data need send to device Answers. This work but
My problem is this special device has fixed tcp timeout (500 ms), Our Network library When we use "Write" command ,same times send data 20 ms same times 50 ms sametimes more than 500 ms (randomly - all device work local network and I check packet times on Wire shark).. This write command add sended data on queue. How we can set this Network library sended real time ?

Sorry I fixed.

1. Make sure that AsyncStreams is not initialized in prefix mode.

2. Can you send a no-op "ping" message? If so send a message every 5 ms.

 

[Hakanunver]

Yes not used prefix mode
And ping avarag e about 1 ms
I think maybe need network library set therad priority ?

 

[Erel]

The thread priority will not affect the latency more than 1ms (if at all). It will be surprising if the latency reaches 500ms assuming that you are sending a message every 1ms.

Sorry We send cmd app on windows ping execute.
You mean need ping packet send in from b4a app to device ? How we can send Ping on B4a ?

 

[Erel]

I meant that you should send a "dummy" message every 5ms from your B4A code.
