title: HM-10 bluetooth pairing with iPhone
body: <p>I am using a HM-10 bluetooth to pair with my iPhone but I noticed that HM-10 can't be paired with iPhone using the "settings". It just won't show up in my bluetooth list. I will need a special app like "Lightblue" or "Bluecap" to pair it. </p>
  
  <p>My question is, if I need a certain app to pair the bluetooth module with my iPhone, why is that many devices such as bluetooth speakers could be paired using the "settings" even without having an app? </p>
  
  <p>Are there any bluetooth modules that could be paired without having an app like "Lightblue" or "Bluecap"?</p>
