Hi there, I’m trying to get a Photon to communicate with a NodeJS Server, but I don’t get it to work. I have a NodeJS server listening on port 3700 and I have this code flashed to the core: TCPClient client; byte server[] = { my, ip, add, res }; void setup() { pinMode(D7, OUTPUT); } void lo…

I’m not sure what the issue might be, but some of these topics might offer some help: [image] Sending large data off Photon using TCPClient I was wondering exactly how fast you can get data off a Photon using a direct TCP connection (TCPClient), and how reliable is it? Well, after twea…

Thanks, I guess I’ll read those first.

Hi again, so I read the examples, and I tried them out too, but they don’t do anything for me. It seems that the photon simply does not connect to my server. Could this be an IP issue? The applications work fine on localhost in my browser, so I assume the server is running, but all connect attempts…

I can imagine you’d need the IP address from the actual device rather than from your ISP. There are several apps available with which you can scan your local network, but a look inside your router should offer the same info.

A typical home network looks something like this: [image] Everything on your home network is assigned an IP address on your local network, typically of the form 192.168.x.y or 10.x.y.z by your router. In this example, the router itself has an internal IP address of 192.168.1.1, the Photon 192.16…

Alright, thank you, I looked that up after Moors7 posted about ISP and I found this: Access localhost from another computer not on network networking, ip, localhost, lan asked by user1151738 on 10:36AM - 15 May 12 That also mentioned p…
