The Core and Photon support REST both incoming (through the cloud) and outgoing using a library. Node Red is REST compatible. The most basic plan is the have Node Red consuming Core/Photon services when required and Core/Photon consuming Node Red service far more regularly. Not wanting to over stre…

In addition to @kennethlimcp said, you can post your Node-RED flow here. It will help to pin-point the issue. Also please check this will help or not. [image] Issue: HTTP input node is too picky for POST requests opened by andysc on 2014-02-10 closed by knolleary on 2014-02-…

@kennthlimcp I spent all of yesterday trying suggestion (libraries, examples etc) from the search and google including the one you have linked. Infact I spent so long going through different peoples iterations of what they said worked and didn’t ended up having a headache and needing to lie down. Th…

@original_pir8 , the problem with you firmware code is, you are using request.hostname = "123.123.123.123";. But if you are using IP Address, then it should be request.ip = IPAddress(123,123,123,123); I modified your code and is working fine for me. Firmware Code // This #include statement was aut…

Thank you sir. I will crack on with my efforts. I hope to use your node too once I am further along. 8 photons, 2 cores pinging away to each other should be fun.

I have been using your code exclusively and it seems to be a problem with the HTTP “stuff”. It is either not working (status -1) or working but timing out with hitting the 5s limit then waiting 200ms to close. Oddly it seems to fail at the start and then without provocation begin working but timin…

@original_pir8 , can you share some more info, like screenshots or your code? I haven’t experienced this issue. Can you share the complete debug output?

I can just not currently as I am at work. The code is what you put up except it has my IP address. Its a very odd circumstance really but with the Serial debug from the core when it fails it actually fails but when it succeeds it timesout :frowning:

I am using the code you stated worked for you in an effort to minimise changes. This is the output from the serial monitor after the spark core boots. It does seem to be completing the post request it just seems to not complete the actual response properly. First Output HttpClient> Connection fai…

@original_pir8 , from log it seems that first the system was not able connect to your server (in this case 94.174.44.159:80), second time it is connecting and proper response is send back. You should see the Node-RED debug out.
