I found another “( window) .chrome.sockets.tcp.onReceive.addListener” on 1 page of app. On this page, the operations related to this addListener do not always work well.
I think this “listener” on the single page should be removed and managed through the provider, is not it?
Another topic: through the realtime debugging of the device (not smartphone but, I saw that the response to the command I send by “send” is fast but the relative “listener” grabs the answer after a few seconds (sometimes even more). normal?
Many thanks in advance
