I have MAX30100 oxygen/heartbeat sensor in M5Stack Heart Unit with which i communicate via I2C of Arduino uno. but it is not even to respond , if i change sda and scl it responds "max30100 initialization ....failed" other wise, if i connect sda to sda and scl to scl it is not even giving a message to the serial monitor , it comes like "init?" and failed. is there any problem in schematic , i was posted a message on the m5 stack website but even not responded. first i want to check the sensor is working or not. is there any another examples, if anyone have idea please give some suggestions
Best regards
