Delay between notification value and logged value, nRF Connect

Hi ,

I hope my question is somewhat related to this topic. I could not get related discussions on my doubt about using nRF connect app on android. I am using using the app to log RSSI measurements from bluetooth devices. However, in the exported file there is no timestamp. Is there any setting through I can export the data with timestamp?

Thank you for your answer.
At first, I had the same problem in an app that I've developed, where I noticed some latency in the reception of onCharacteristicChanged callback (when I get characteristic notifications). So, I thought it could the same thing for the nRF Connect log.
It is strange that I get latency in notifications in my app though ..

Hi,

The reason for the delay is that the nRF Connect when notified collects the logs in memory with timestamp and then only flush the logger every +second, even if notifications comes more often. This is to avoid being unusable when the notifications come too often. But the timestamps should be the same even though there is delay.

Best regards
