title: Bluetooth Low Energy: Reading Fitbit Zip Data from Raspberry Pi
body: <p>I have a Fitbit Zip and I want to extract its data from Raspberry Pi using gatttool. </p>
  
  <p>I can connect to it, figure out RX, TX handle etc. I understand I need to enable listen to the CCC handle like this</p>
  
  <p><strong>char-write-req 0x000c 0100 --listen</strong></p>
  
  <p>But before that, I need to enable reading the sensor (or series of action) through the TX handle, something like below. </p>
  
  <p><strong>char-write-cmd 0x000b </strong></p>
  
  <p>I am not sure how to figure out that  or the series of action that needs to be done before I can listen. Can anyone please help?</p>
