please help me if issue is resolved , i am also facing the same issue.
You need to make the modification of resistors thing in the sensor and it will work fine

Shall I have to vary the resistance or change the circuit connections , can u please detail me out , I have been stuck in this from past 3 days.
using setClock function of Wire library ensure to maintain the clock speed to be 100000 in the setup function

Description of the issue
I can't merge MAX30100 code with any other sensors i always get 0s
Output from MAX30100_Tester example
Details of my setup
The issue is kinda complicated as MAX30100 had been modified by desoldering the 3 resistors 4.7k and making external resistors .. I have been trying to make MAX30100 works with another codes but with no use on Nodemcu v2 / Arduino Uno .. tried to just upload the data on Ubidots but i get zeros always .. i even tried to use Arduino as master and send data through Serial communication but no use i get zeros value .. I traced the code all along on the MAX30100 code alone if i added delay more than 90 ms it will not detect any beat ... So is there anyway i can merge MAX30100 with ECG Sensor AD8232 and upload the data to Ubidots ?
One of my trial codes:

}
void loop() {
