title: Can I sniff a BLE communication between my multimeter and my smartphone?
body: <p>I am currently trying to manipulate a multimeter (Zoyi ZT-5BQ) using an Arduino board, but I don't know the protocol that uses my multimeter to change the reading mode (in example, from ohmeter to termometer).
  I have tried to pair my AT-09 module to the manufacturer's app (Bluetooth DMM) and see what does it sends when I try to change the reading mode from the smartphone, but AT-09 is not detected by the phone, and I guess it's due to the MAC address of my module.
  Is there any way I can sniff between the communication of my smarthphone and multimeter?</p>
  <p>Thanks in advance!</p>
