The client port is coming along. It needs to be stabilized. If I wait for the initial return response and then close the connection, the process is pretty clean. However, if I leave the connection open and the server closes the connection, it sends the Photon into a tail spin (communication loop; one red flash, etc) – it will disconnect from the cloud and go in circles… see quoted text below.
I am not quite sure how to keep the network stack stable? Is the network stack sensitive?
I’d take suggestions on ways to make the code better or questions.
Should I work towards getting the response expected and close the connection before the server disconnects? It would seem that I should be able to detect the remote closure and keep things sane? @ScruffR, can you point me in the right direction or give me some areas to investigate and/or avoid.
EDIT: May need to review this post for ideas.
For those that would like to try and work with the client and send suggestions, that would be great. The repo working towards a stable port is:
