we have a solution using UWB from Qorvo using the Nordic 52833.. however

[rexxdad]

this works well with an Apple 11-13, but on 14+ Apple has removed the second antenna from the phone, so it cannot do ranging natively.

the AR approach does not work for our blind users (camera they cant see and it kills our voice driven UI)

AND Android UWB is different than IOS UWB.. 

anyhow.. we want to explore a user held device also with a qorvo 52833/40  to run FIRA ranging..  this works.. (think phone case)  but

now I need to connect the ranging process and data to our phone app.. 

does the 833/40 have the horsepower while UWB ranging (FIRA) to handle another BT connection to our phone app 

the data is small, and not terribly frequent

I see the ranging sample app.. over an OOB BT connection..  this would be similar output 

so our phone app would connect to the device (bt?)

send commands to the nordoc resident app

the nordic resident app would execute start/stop ranging, FIRA commands lo the FIRA UCI app that Qorvo provides

and send the ranging data to the phone app. 

the device would be battery powered, not wire connected

and if it has an IMU we could use that for user info on orientation.

Hi Sam

Håkon is out of office, so I've been assigned this case in his stead.

I'm afraid this will be out of our hands, as UWB is not something done on the nRF52833 inherently. I believe Qorvo only uses the nRF52833 for Bluetooth connection/pairing to handle the data part of setting up UWB. All firmware related to UWB will be done by Qorvo/Apple in this case, and you should refer to their support channels for help with this issue. Let me know if I'm misunderstanding anything and please explain what assistance you require from Nordic on this.

Best regards,

Simon

thanks.. I see that both SOC's I use have a Nordic 52833/40 as the host processor for the solution

DW3001C  which runs the 52833 (built before the 840 was released)

and the Murata 2AB which runs the 52840

I didn't mean the nrf chips DO the UWB signals.. they run the UWB control APP.. fira/UCI in my case. 

Qorvo/Murata do/choose not to answer my question about adding another/changing the app. 

in both cases I want to replace the USB/serial port component of the existing fira UCI app with Bluetooth transport. 

the 833 will be very limited output

the 840 will be the brunt of the work. 

does Nordic provide tools or guidance on performance measurement on these devices?
