Talk to my blynk from a third party?

Need Help With My Project
1

I need help urgently. I may have purchased this product in error.

I need to communicate with the blynk using a custom app (not inside the blink sandbox)… is this possible? Can I communicate directly? I need to be able to make my device respond to my server’s events (or directly respond from my phones push notification.)

Thanks in advance,

Jeremie.

Hello. Sure. What about HTTP API? http://docs.blynkapi.apiary.io/

I was looking at this- my issue is id like to communicate directly with my chip… Im trying to use a stepper motor, timing is important…

Blynk works over the internet or USB or BLE.

You need to explain better what your task is.

Well I want to make an iphone app (I am a iOS Developer by profession) that can control a stepper motor… from what I gather here, I would either have to communicate using the blynk app or using the http rest api as a middle man… both of which wont work for my project. do you guys have an iOS SDK which would allow me to communicate with the board in real time ? (ill have to send hundreds or perhaps thousands of commands to make the motor turn…)

Currently iOS SDK is available only for commercial use.

However I don’t think that sending thousands of commands will solve your task. Why don’t you send the signal that will trigger the function? For example you send start/stop and speed parameters, and then the hardware does the rest?

Sure, the above makes sense, about sending the signal that triggers a function… is there an example somewhere of a function triggered by http request so I can hack that away?

Thanks,
Jeremie

send HTTP request to a V pin and then trigger a function

http://docs.blynk.cc/#blynk-main-operations-virtual-pins

BLYNK_WRITE(V1) // HTTP PUT 1 to V1
{
    if(param.asInt()){
    //start yourFunction();
    } 
}

You could also use websockets. Example https://github.com/vshymanskyy/blynk-library-js/blob/master/examples/nodejs/client-tcp.js
