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,

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

I am mainly familiar with what the Nordic provides, so I can't really comment on how much processing power is left on a qorvo 52833/40 that runs FIRA ranging. 

If had questions on how to do this however, I might be of help. 

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

If I am understanding you correctly you just want to send the ranging data. So if you are refering to the ndt sample, that wouldn't be comparable processing wise, as that is also calculating the range itself.

yes, I was just think about command/data flow paradigm... 

```text

connect,

start ranging(maybe with specific device) ,

       something does the processing(ndf,fira...), callback for data and status

       callback_handler 

             with data/status, send to remote

stop ranging

```

I am thinking near field for the transport.. as there may be multiple users of the device in the same room and BT has a long range, NFC can't be confused on who the remote..

but we'd have to add a nfc antenna too.. 

i'll use BT in the near term to  prove it out. 

[Elfving]

Sure. Try it out. 

I believe UWB works a lot better than the NDT, but NDT is cheaper.

but can I use uwb out to target device(s) for ranging

AND

uwb to phone app for data transfer

concurrently. two different session types

if I don't use  uwb  it opens up use on up more phone devices
