title: About HM-10 BLE with multiple device communication
body: <p>I'm doing a project that need some BLE communication.
  For now, I have two device in my project, A and B, A they all using HM-10 BLE module and A is in slave mode B will be in master mode.</p>
  
  <p>When active, A B will connected and transfer data. I also want to have my iphone connect to B, is this possible? Like two master connect? Since I see a master in bluetooth can have connection up to like 6 or 7 device.</p>
  
  <p>I have read the datasheet and did many search on google but didn't find any answer.</p>
  
  <p>Can someone help me with that or where should I go for help or learn? Thanks.</p>
