Importing serial data from Bluetooth sensor

Hello, I have been through Lessons 1-6 on Chris’ tutorials but not sure if the rest is a fit for my ask : am trying to develop an IOS app that collects and manipulates serial numerical data from a custom Bluetooth LE sensor to generate audio and visual feedback so the question is:

  • How to modify Swift / View controller code to import data to the iPhone X from a BLE sensor

thanks for any pointers, Ramesh
