title: BLE Clarifying the Read and Indicate Operations
body: <p>I'm writing code for Pycom's Lopy4 board and have created a BLE service for environmental sensing which currently has one characteristic, temperature. I'm taking the temperature as a float and attempting to update the characteristic value every two seconds. </p>
  
  <p>When I use a BLE scanner app, whenever I try to read, I read a value of "temperature10862," which is the characteristic's name and uuid. Yet when I press the indicate button, the value shows the correct temperature string, updating automatically every two seconds. </p>
  
  <p>I'm a bit confused overall. Is this a problem with my code on the Pycom device or am I simply misunderstanding what a BLE read is supposed to be? Since the temperature values are obviously being updated on the device, but why does the client, the app, only show these values with an indication rather than a read?</p>
  
  <p>I am sorry for any vagueness in the question, but any help or guidance would be appreciated. </p>
