Feather BlueFruit not showing in bluetooth list macOS

by ith on Tue Sep 18, 2018 2:17 pm

Hi,

I'm using a Feather Bluefruit 32u4, purchased about 18 months ago.

I've installed everything and all seems fine. Even got the sketches bleuart examples to run and communicate with my phone (onePlus 3) through your app.

Problem is - when i scan for bluetooth devices with my macbook pro (early 2017, osx 10.13.4 high sierra) - it doesn't appear on the list of available devices, even if it's not paired with another device. Other bluetooth devices appear as normal.

Pasted below is the "bluetooth" part of the system information.

Am I doing something wrong? Is the board defective or too old?

Thanks so much,

ith

That’s normal.

The protocol now known as Bluetooth Classic and BLE are different and incompatible protocols that happen to be managed by the same working group (which seems to love confusingly-similar names).

BT-C devices have to obey a predefined set of rules and device categories. That doesn’t leave any room for hackers, but makes an OS developer’s life easy.. they can write a complete and correct BT-C support stack from the spec, and don’t have to test it against every device in the world.

BLE is more free-form. It has a few rules about how data is arranged, and there are some standard profiles for things like BLE keyboards and mice, but ultimately the developer decides what messages to send and what to do with them. That’s great for hackers, but makes it impossible for OS developers to write a complete BLE system. All they can do is provide communication with the BLE radio and throw in some functions to handle the basic data structures. Beyond that, it’s an application’s job to locate a BLE device, open a connection to it, and communicate with it.

The Mac’s Bluetooth control panel and menu item only show BT-C devices, and don’t show BLE devices.

thanks mike, the behavior is now clear. I'm going to use the BLE guides to create the communication with my board.
