I am working on IoT project over google cloud. I use Publish/Subscribe to allow devices contact each others. I developed the backend system using nodejs, then I will develop Mobile app that will use google library to publish/subscribe.
The problem that I face now is that. Does google have any C/C++ Library for contacting PubSub/googlecloud API or not, and if not, is there any alternative way to keep embedded devices (programmed in C/C++) updated with mobile applications actions.
Note: I need real-time control between mobile app and embedded device.
Thanks
Google Cloud Pub/Sub has a HTTP/JSON based API (under the API Reference tag in the sidebar), so you can roll your own library in this case.
The client APIs that Google currently supports are listed here. If you can run Go or Java on your embedded device (both a lot less common than C/C++ on embedded devices, and usually only supported if you stretch the definition of "embedded"), you can have a fully-supported client library.
