How to get the advertised data in NRF connect

Hi, I just follow the suggestion about advertising the Heart Rate.

Bangle.setHRMPower(1,"test");
Bangle.on("HRM", function(hrm) {
  NRF.setAdvertising({
    0xFFFF : [hrm.bpm]
  });
});

I would like to make sure if it works, how can I find the advertised HR data in NRF connect?

Hi - the issue is you clicked 'connect'.

Make sure you're disconnected, then stay on the left-hand 'Scanner' tab, and expand the tab for the device you're interested in and you'll see it

Hi ,Gordon, that's all i got in 'Scanner':
1 unknown device
1 windows 10 device
1 bangle.js

I don't find any information about HR from bangle.js or unknown device

It says 'Service data 0xFFFF Data 0x57. Since the code above was0xFFFF : [hrm.bpm]` that's what you're seeing.

0xFFFF is not a standard UUID so it's not decoded by the app, but 0x57 in decimal is 87 so I guess that's your BPM

Thanks a lot!
I am building my own android app to get data.
I also would like to get the steps counter data. I don't think I can get it from advertising. As it required to be summed and reset per day. So I am thinking to get data from the ''Recorder'' app in bangle.js. How can I access the "Recorder" 's csv in Storage on my android app?

Best bet is to look at the interface html in https://github.com/espruino/BangleApps/tree/master/apps/recorder

You have to read the contents of the storage file, which you can do with code like this: https://github.com/espruino/EspruinoAppLoaderCore/blob/59f80bb52a38da12cb272f9106cb3951b49dab2e/js/comms.js#L394

However I would have thought you could send steps via advertising relatively easily if you wanted - I don't see the reset at midnight being a big issue.
