nRF52832 software

[Pete]

Hello.

Which application can I use to monitor and configure a smart wristband with nRF52832? I would like to check its firmware, update it and see all the info about the device. 
This is a chinease smart wristband with a heart rate and ECG functions. I know that it has nRF52832 chip and the info from the manufacturer is very poor, as you can imagine...

Thanks in advance.

BTW, I don't know is it useful to publish a link to the product with nRF52832 I have but here is it.

Maybe it will help to understand the device I'm talking and asking about...
