I want to create an app which can connect to a device(lets call it a gateway) which is connected to other devices. I want all the connections to go via Bluetooth low energy.
From what i reckon is that the "gateway" needs to be the master and all the other devices need to be slaves. But how about the mobile app? Can i make it a slave but still use it to connect to the "gateway".
What is the best way to create such a network? Is a mesh network possible in this case?
Thank you for the help
