Log BLE datas using NRF connect Android

[Romain Bailly]

Hi,

I am using NRF connect on Android to observe the activity of a BLE sensor.

I use the app to export the datas of the sensor to a csv file.

Using "More" -->  "..." --> "Save" --> "Export graph to csv"

The csv file I get seems limited to 100 lines of datas.

But I would like to export more lines as I know that the sensors send more than 1k of datas.

Is there a way to improove that ?

I tried to change a few settings on the app : scanning period, number of packets, swap time.

But nothing worked.

Thanks for your help,

Kind regards.

Hi Bailly,

Our app team confirmed that currently the feature is limited to only 100 records. There is no configuration to change it at the moment.

We have registered the interest to improve this. However, we do not know when an update will be available.

What do you think about writing a custom application to handle the use case?

Best regards,

Hi Hieu,

Thanks for your quick answer.

Yes we could discuss about a custom app.

Let me know how you want to proceed, if you want to organize a webmeeting.

Kind regards,

Hi Romain,

Perhaps a web meeting is not necessary.

There is a very nice guide at the official Android website. It had helped me get several things to work in the past. Would you like to try following that? Here is the link to it:
