Grove-Finger-clip heart rate with shell

can you tell me the address of this sensor ???

below is the code of reference on mbed, but it doesn’t react at 0xA0…

what’s the problem??

#include “mbed.h”

I2C i2c(I2C_SDA, I2C_SCL);
const int addr = 0xA0;

int main() {
char heart_rate;
while (1) {, &heart_rate, 1);
printf(“heart rate: = %d\r\n”, heart_rate);


Please use the following code

[code]#include “mbed.h”
#include “USBSerial.h”

USBSerial serial;
I2C i2c(P0_5, P0_4); //instead of P0_5, P0_4 specify the port pin number of the sda,scl of your board
const int addr = 0xA0;

int main() {
char data;
while (1) {, &data, 1);
serial.printf(“heart rate: = %d\n”, data);

and let us know if you have any other issues.

Thanks and Regards
