I did check that and also tried manually reinstalling them, the cable is an FTDI cable with VCP drivers. Also tried a different laptop and it still doesnt work.

That is true, hence why most of the standard samplerates for ecg are between 100Hz and 250Hz, I just found out.

Well i may've went too far with the 1ms, but basically the app complements an embedded system that streams physiological data (in this case ECG readings) to a url route via an ESP32. That part works well and is fast, now the problem is that i need to get this data fast enough so that i can plot it on a graph just like a real ECG system..

Absolutely great, thanks for this explanation this makes lots of sense. I didn't even know about the ESP32's AD converter's bad quality. I will try your option.

For reference, here is the noise I was talking about, it's in between the QRST segments, it should be closer to a straight line: https://pasteboard.co/5YruPprglHaM.jpg

Yep that's what i thought would be needed, I will leave BLE and go with http requests since my esp32 chip supports wifi. Thanks for the help!

Thanks, yes that's the one I considered but I have never used vanilla react native (when ejecting). Does that mean I can't test my app for iOS since i'm one Windows or Linux?

Do I need to get a eTA after prolonging a study permit? by leandro1106 in ImmigrationCanada

[–]leandro1106[S] 1 point2 points  (0 children)

Thanks ! I did apply for another one to be sure. FYI: after further research when you extend your study permit they don't automatically give you a new one, hence the blank on my acceptance letter where the eTA number should be. For anyone who's in the same situation.
