Hi, I am trying to use BLE capability in Arduino Genuino. I am using the library curieBLE, but all the examples are for Arduino as a peripheral device. Is it possible to use the arduino as a central device? If not, is this a limitation of the library or the HW? Thanks!
If by “use the arduino as a central device” you really mean “use bluetooth as a master” then, yes.
To do this, you need to configure Bluetooth as a master. Arduino just communicates with the serial port, and doesn’t know or care about the condition of the bluetooth device.
If you are using a library, there is probably a facility for configuring Bluetooth as a master included, and it is just a matter of nomenclature.
