Clarification on DWM3001 Foreground Ranging with Multiple iPhones

Wireless Connectivity Ultra-Wideband

We’re evaluating the DWM3001 with iOS Nearby Interaction for a large deployment and need clarity on one key point:

Can one DWM3001 accessory (e.g., Nordic host) range with multiple iPhones in foreground mode?

Context:

  • iOS distinguishes between foreground (no BLE pairing needed after discovery) and background (BLE pairing required) modes.
  • We’ve tested Qorvo’s QNI sample successfully for 1:1 ranging in both modes.
  • BLE has a 1:1 limitation, but in foreground mode, UWB takes over after discovery without persistent BLE connections.

Question:

  1. Is many-to-one (1 accessory → multiple iPhones) supported in foreground mode?
  • Some sources suggest UWB inherently allows this (with bandwidth limits); others claim 1:1 only.
  1. Does the current SDK/firmware support this, or can it be modified to enable it?
  2. Are there any samples or documentation for this use case?

Any clarity or guidance would be greatly appreciated!

Yes, it can in principle. You require niq lib version > 2.0.0. I was a lucky from first testers and it works. So if your volume is high, ask via your Qorvo point of contact, if you have no volume, wait for a new release with this library version.
