Hi, I have a Core 2 and have installed UiFlow v 1.10.7
When I power the unit on it goes straight to connecting to WiFi and there isn't time to access the Setup or App menus. The same when rebooting, the WiFi is accessed so quickly that you cannot access Setup or App menus.

Amazing! Thank you very much Pavelprosto.

@teastain
The Unit Cam and Timer Cam units are greyed out on UI Flow for the Core 2.

@ajb2k3
Thanks for the advice but I am hardly going to buy a shop brought SPO2 meter to check the M5 Heart Rate unit against.
Calibrating the unit?? No instructions were provided with the unit to do this.
I persisted testing it on myself many times and there is no way my heart rate fluctuates between 60 and 210.
Anyway M5Stack guys were helpful in trying to assist me too so that was also appreciated.

I was dissapointed to find that my Core2 does not support Unit Cam. As the Core2 is a more expensive controller than the first generation Core I would appreciate this being resolved asap please.

I note that adding speaker volume to Core2 was suggested over two years ago and still has not been added. As the Core2 is a more expensive controller than Core I would appreciate this being resolved asap please.

Thanks teastain,
yes the heart rate unit is useless. It does not produce accurate results no matter how much you try and adapt the way you use it.

Hello, I received my Heart Rate Unit today and tried using it with my Core2 which has an M5Go Bottom fitted.
The sample program on UI flow loaded but the results that I am getting for my heart rate very between 58 to 208 beets per minute when I continue to put my finger on the sensor. There is no consistency with the readings.
Also my 02 level readings very between 89 to 98, again when I am making repeated readings.
Do you think my unit is faulty?

What really caused the issue!
Further to my last post I have found that the real issue whereby my Core2 cover caused the Core2 to shut down when the cover was pushed back in place was due to damage to the Core2 cover.

I obviously had damaged some of the components of the accelerometer when I removed the Core2 cover with a screwdriver!
I hope I can purchase just a replacement cover.
Something to be aware of when removing the Core2 cover.

Hi Felix,
PROBLEM SOLVED!
You are right. When I removed the CORE2 cover and replaced it with only slight pressure the controller boots up.
SO the trick is not to push too hard and push the cover too far in, or as you say isolate the metal parts with tape.
Thank you for problem solving this for me and probably for others who have the same issue.
Cheers
