Hey all, I’ve been trying to send a simple TCP packet via my hub, but haven’t had any luck. I’ve tried writing both a SmartApp and a Device Type to transmit this, without any luck. Other network traffic seems to be working just fine to the receiving end of my TCP server. Can anyone help point me in…

Have you set the destination ip or port?

Thanks for your response. The destination IP and Port are converted to their hex values in the first section, and then assigned as the variable myNetworkID, which is then passed as the third parameter for transmittedData. Is that how destinations are supposed to be assigned? If I’m missing somethin…

Check your options and are you looking for a response in the parse method? I don’t see any callback method registered: type:“LAN_TYPE_CLIENT”, protocol:“LAN_PROTOCOL_TCP”

Oh my goodness, adding those options did it! No parse response needed for my code (from my understanding we still can’t parse TCP responses, or has that changed?) Thank you so much!

With the help of this post I got smartthings to send tcp commands from device handler. Can someone confirm that there is no way to read tcp response? My parse method gets triggered but payload seems empty.

I’m having same trouble. See this response to my query, seems smartthings is broke: [image] HubAction JSON response Writing Device Types Ok thanks for letting me know. @rappleg any idea when this may be released ?

Yep, an empty response is the broken platform. Pending with ST’s engineers for a patch for months now, I can only hope they carve out some time to deploy the patch (apparently it’s coded but just been pending testing/deployment).
