title: Movesense decode SBEM data from LogBook
body: <p>I'm trying to get the LogBook data over BLE to my App.
  This works fine for JSON, the data seems accurate.
  But it takes along time due to the JSON encoding.
  Getting the SBEM data is way faster. But I can't find any documentation on the encoding. I found out that the "Content" string is Base64 encoded.
  It starts with SBEM which means, it is uncompressed as stated here: </p>

  <p>But I couldn't find anything else.</p>
  
  <p>Has somebody further information on that or found out what the encoding is like?</p>
  
  <p>Best regards
