Matthieu: Please try to close other apps that might be working with the pulse-oximeter (native app, Light Blue) and try a couple more times. Make sure that the device is turned on and streaming data when you try to connect. Please let me know if you can get past that error.

Valeriy Kovalenko: restarted my phone to ensure it woule disconnect from all apps. Worked on the first try!

Thanks a lot, and have a great day!

Matthieu: Awesome! Thanks for letting me know! How difficult was the connection process for you? Is it a self-explanatory wizard or did you check the documentation? And how many candidates for SpO2 / HR were there during the filtration process?

Sorry, too many questions, but I'd like to be sure that the process is easy enough for everyone to use.

Valeriy Kovalenko: that is no problem! I totally understand!

I quickly checked the documentation yesterday, so had plenty of time to forget its content. I didn't have to go back to it as your wizard is self-explained and very user friendly.

Duuring the filtration process, I ended up with just 1 candidate for each process. Delay in the value display is of about 1 sec, so fairly accurate in time!

Matthieu: Thank you!
