Hi there,
I’m currently doing a project and wanted to use a heart rate module combined with my huzzah32 (esp32).
I’m connecting the module to the dedicated SDA and SCL pins on the huzzah and I added a 4.7K ohm pull-up to both the signal lines.
On a I2C scanner the module shows up with address 0x50.
Now I seem to be getting a connection for a while but after a couple of readings the connection just dies 
If you have any clue feel free to reply.
Module test code:
[code]#include <Wire.h>
void setup() {
Serial.begin(115200);
delay(1000); // read on some post it worked magically for some people
Serial.println(“heart rate sensor:”);
Wire.begin(23,22);
}
void loop() {
Wire.requestFrom(0x50, 1); // request 1 bytes from slave device
while(Wire.available()) { // slave may send less than requested
unsigned char c = Wire.read(); // receive heart rate value (a byte)
Serial.println(c, DEC); // print heart rate value
delay(500);
}
}[/code]
