thank you very much.
Thanks to other people for contributing to this discussion
I completely understand what you said. there are totally 2 ways.
1- checking tcp 3483 port to understand by netstate command in sh file
scripting.
if it is connected GPIO pin number is going to be high and LED will be
on.
2- using CLI command via telnet from linux command. I guess it is
accessible in picoreplayer. I have to test it. I do not know about Curl.
but I guess it is not too complex.
I studied software engineering and have some experiences about networks
and security. I can handle it.
today I run squeezelite emulator on my windows 10 as a client and
logitech media server and I run that command you write with termux on my
android phone.
it is worked and responded : " xx%3Axx%3Axx%3Axx%3Axx%3Axx connected 1"
.
when it is not connected responded :
"xx%3Axx%3Axx%3Axx%3Axx%3Axx connected %3F " or
"xx%3Axx%3Axx%3Axx%3Axx%3Axx connected ?"
"%3F" is mean "?". not responded 0 in result.
however right not I don't know Linux command to cut "1" from result. I
should work on it.
all in all I must write a script in this form :
every 15 20 seconds while true :
do
//check connection
//if connected turn on led
end
it must run from startup until turn off. what method do you think is
more reliable to run every 15 or 30 seconds. I don't know telnet(curl)
method is Affected
in bandwidth or not. I always use at least 10 zero w picoreplayer on my
network. this checking script must be run on every zero w every 15 20
seconds for checking connection.you think is there a problem about
telnet from many zero w to lms server ? in this method , i'm just
worried about bandwidth and this scriot maybe Disrupt while listening to
music and audio syncing lms.
what you think about this ?
