macOS Airport

macOS WiFi Wireless Scanner

If you are looking for a basic WiFi scanner for macOS then the command line airport utility may fit your needs. The utility is located at: /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport

Typing the above command path can be avoided by creating a symbolic link to the command in /user/sbin/ by copying and pasting below into a terminal window.

`sudo ln -s /System/Library/PrivateFrameworks/Apple80211.framework/Versions/Current/Resources/airport /usr/sbin/airport`

This will allow you to simply type airport in the terminal window to execute the command.

BLE Nano and the nRF51822 SDK

If you've tried using the nRF51822 SDK with the BLE Nano (after following the RedBearLab guide) you may have come to a dead end.

Even the simplest examples didn't work for me. I assumed I had a dead Nano (despite the upload process seeming to work fine).

The reason turned out to be that the latest SDK versions assume you have a nRF51822 chip with 32KB of RAM rather than the 16KB that the nRF51822 on the Nano has.

James Willcox explains this in a post to the RedBearLab BLE Nano support forum.
