Bluetooth Low Energy Characteristic Value from Byte












2















Background:



I am following this tutorial from raywenderlich about connecting a bluetooth low energy shield to my project. I am using the Adafruit BLE friend.



Question:



I cannot figure out how to specify the UUID for the BLE friend. Here is a picture of Adafruits information about the characteristics:



Adafruit's documentation on the characteristics



Here is the link to the page on Adafruits page



How can I format the characteristic UUID so it is in this style: F38A2C23-BC54-40FC-BED0-60EDDA139F47



Thanks for any help,



Joel

          I believe that the CBUUID constants can be created for the Service and Characteristic as follows.



          let kServiceUART = CBUUID(string: "6E400001-B5A3-F393-­E0A9-­E50E24DCCA9E") // UART Service
          
let kCharTX      = CBUUID(string: "6E400002-B5A3-F393-­E0A9-­E50E24DCCA9E") // TX Characteristic (Property = Notify)
          
let kCharRX      = CBUUID(string: "6E400003-B5A3-F393-­E0A9-­E50E24DCCA9E") // RX Characteristic (Property = Write without response)


          I don't have a BLE Friend available to verify with.

          A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

          Image
          0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{...

It is not appropriate to pass these predictions into an evaluation metric. Can someone explain what does it mean?
