title: iOS: scanForPeripheralsWithServices can't find device while nRF Connect app is able to find it
body: <p>I have a BLE peripheral running on Raspberry Pi with <a href="https://github.com/nettlep/gobbledegook/" rel="nofollow noreferrer">gobbledegook</a>.</p>
  <p>In parallel, I have an iOS app working as BLE central which does a scanForPeripheralsWithServices with nil in order to detect all the devices around.</p>
  <p>I'm able to detect a few devices, but not the one running on Raspberry Pi.<br />
  However, when scanning with the nRF Connect app on iOS, I'm able to see it.</p>
  <p>How is that possible? (I assume that nRF Connect is also using Core Bluetooth...)</p>
