Bluetooth 5 master

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).

Yes, that's correct. Better go through some BLE basics, e.g. this presentation of BLE 4.0 is good intro (remember that newer standards bring some new features but core principles and backward compatibility remain).

I am solely interested in Bluetooth 5, does BLE comprise the version 5 too? Thanks

Hi, I suppose then there is not a hardware requirement for being a master, it is only defined by the software. Is this correct? I have not begin digging into details yet, I just saw a video on youtube demonstrating the nRF52 streaming video to a Samsung G8.

Yes, nRF52 can act as master. Buy a nRF52 develoment kit:

www.nordicsemi.com/.../nRF52-DK

and download the SDK:

developer.nordicsemi.com/.../

The SDK have examples that implement BLE master.

Nothing much, just use some SW stack or implement yours (yes, that's a joke;). There is obvious choice of Nordic S132 and S140 Soft Devices (aka lower-layer BLE stacks) but you can go with Zephyr or other open source projects if you want. Then depending on stack and SDK you choose simply see some examples and you are almost there. Is this the answer you were looking for? Your question is really vague and opened to interpretations... how much you read about the technology, stack, typical architectures etc.? You know what is LL, L2CAP, GATT and GAP?
