<![CDATA[Heart rate unit with M5Stick]]>Hello! My heart rate unit is working with m5stack, but it dosen't work with m5stick. Code is the same. When I turn on m5stick sensor flashes for about 0.5 second and then remain dim, so serial monitor return 0 for forever. What is the problem? Thanks.

It could be that the M5Stick can not provide enough power for the heart rate monitor.
You could try connecting one of these

between the Stick and the heart rate monitor and use the other connection to provide an additional power supply for the monitor.
