Bluetooth 5 master

[klin]

Hi, I am relatively new to the bluetooth technology. What's needed to implement a master? Can I use a nRF52 to act as one? Thank you

Firstly understand that Bluetooth 5 is more marketing label on piece of paper which has several thousand pages. Many things, many features, several completely different stacks (Low Energy vs. BR/EDR aka "classic"), many optional features (= you can have two "Bluetooth 5" devices on the table but they will talk more or less the same as any BT4.0 device or even not talking at all because they use incompatible parts of the stack) etc. So be careful with your "light-way scratching of surface". Bluetooth 5 is usually mixed with new features in LE (Low Energy) part of the spec, at least on this forum (note that Nordic manufacture today only chips which use LE stack, no support for other Bluetooth radio protocols).
