Communicating with Puredata over Network

alaimodiloro

Hello,
i'm currently working on my master thesis in the field of active noise control. I started by using Puredata on my Desktop PC and want to port my work over to be used with Bela, which seems to be a nice Platform for this purpose.
I'm wondering if someone already came up with a easy approach to control a pd patch that is running on bela over ethernet for example by using another instance of puredata as a client on the Desktop side. As far as I read here, the netreceive object was being ported by Guilio. Could netsend be ported as well, what were the steps needed for netreceive? Or is there any other simple approach by using mrpeachs externals such as tcpsend and tcpreceive and so on?
the goal is to have a client side control application that is as flexible as possible, with the ability to send messages and receive messages or arrays for scoping from the puredata patch running on the bela. what would you suggest?

Sincerely yours,
Alexander.

after some reading I think I might just have to live with the diversion of using the render.cpp as a relay station, am i right? or is there a chance of establishing a direct communication between puredata on bela and puredata on a client pc?

Hello,
the current option is to go for custom code in render.cpp. It should not take much effort to adequate [netsend] to the required standard (i.e.: avoid using network in the audio thread, which is what Pd does and is bad ). This involves writing the messages to a circular buffer from the audio thread and receiving from the buffer and relaying them to the network from a separate thread. Unfortunately though I do not have much time to look into this now.

I remember trying to use iemnet [udpsend] and [udpreceive] in the past. While they were appropriately threaded, they were allocating memory in the audio thread, which is equally bad. I have not tried mrpeach's ones though.
