I am brand new to the Particle ecosystem and programming my Photon. Just to give some context to my question, I want to do a project where I want to stream data as quickly as possible. I will be dropping my Photon with an motion sensor, and I want to stream the motion data to my laptop in some way. …

Any kind of TCP/IP connection is going to add latency, even on the local network. I think the smallest amount of latency would be to have the Photon send UDP packets to a program listening for them on your laptop – that way there’s no TCP or cloud overhead. An alternative might be to log all the da…

@potatotron Thanks for the quick response! Where could I go to learn more about a TCP/IP solution? I have never done any network or internet-connected applications before, so I am pretty new to all this.

Here's some sample code using a Core to send to a Node.js server, hopefully that's enough to get you started. [image] Simple UDP program breaks the core Troubleshooting Hey all, Just wanted to reach out to see if anyone else is having this problem and/or if the Spark tea…

SSEs are rate limited to 1p/s, which is not nearly enough for a falling object.

@cmbrooks here is example code to read udp packets in nodejs. This is currently what I worked out and use very successfully to read data sent from the core. The example code in the Simple UDP program breaks the core will work for sending of the data. var dgram = require('dgram'); var udpServer = …

Sorry for the double post. Just a thought, if you don’t have to react to the data in a “live” fashion and if there was enough space on the photon you could save the data to an array on the photon and transmit after. or have it transmit once every x milliseconds whatever is buffered up via udp cons…

Hi @SomeFixItDude , i’m also interested in streaming stuff from and to my photon’s would you mind adding a small example showing how i can stream data over UDP on the Photon side?

Here is a small example that sends a udp packet to 10.0.0.3 from the linked example. UDP Udp; unsigned char TxMsg[12] = { 1, 254, 1, 254, 1, 254, 43, 212, 71, 184, 3, 252 }; void setup() { Udp.begin(9000); } void loop() { if (WiFi.ready()) { Udp.beginPacket(IPAddress(10,0,0,3), 9000); /…

So when i get you correct, data streaming does not mean you open a connection and send continue data over the Net, like how serial communication works? Instead you send short package continue. Thanks
