I am very new about the Azure and IOT. I configured my device and I can send message and print through “Device Explorer Twin” but actually I need other solution.
I have very custom developed Opencart and I need to send customers invoice to printers but I can send only pure texts.
I think there is no any SDK for php but I am looking for a solution.
many thanks in advance
