When call pox.update() in the loop, Arduino don't read Serial data from RX pin
Closed this issue · 7 comments
- I read the README (on master) thoroughly
- I ran the MAX30100_Tester and I'm going to paste the output down below
- I filled in all the details of my setup down below
Hello friends of the community. I facing this error a quite long time and I hope you can help me.
When I call the pox.update() method into loop, the Arduino don't receive the entire data from Serial port, who it's connected to a HC-05 bluetooth module. But when I comment it, Arduino receive the data quite well. The variable "palabra" store the data from Serial.
The data of my sensor from the Tester example:
Initializing MAX30100..Success
Enabling HR/SPO2 mode..done.
Configuring LEDs biases to 50mA..done.
Lowering the current to 7.6mA..done.
Shutting down..done.
Resuming normal operation..done.
Sampling die temperature..done, temp=34.75C
All test pass.
Press any key to go into sampling loop mode
My setup:
- Arduino hardware: Arduino Pro mini ATMega328P 5V 16MHz
- MAX30100 breakout: RCWL-0530
- Arduino framework version: 1.8.13
- MAX30100 library version: 1.2.1
My Arduino code:
void loop() {
if (Serial.available() > 0) {
char incomingByte = Serial.read();
if (incomingByte == 'T') {
palabra = getStringfromProgMem(3);
c = 0;
} else {
palabra += incomingByte;
}
}
display.clearDisplay();
pox.update();
estado ? (enlace()) : (noenlace());
unsigned long tiempoActual = millis();
if (tiempoActual - tiempoAnterior >= intervaloEvento) {
rate = pox.getHeartRate();
spo = pox.getSpO2();
if (rate && palabra != getStringfromProgMem(3)) {
c++;
}
if (c == 60) {
c = 0;
}
Serial.print(rate);
Serial.print(',');
Serial.print(spo);
Serial.print(',');
Serial.println(c);
tiempoAnterior = tiempoActual;
}
mostrar(rate, 15, 35);
mostrar(spo, 105, 35);
mostrar(getStringfromProgMem(0), 10, 52);
mostrar(getStringfromProgMem(1), 100, 52);
display.display();
estado = digitalRead(STATE);
}
hi,
how can you solve this problem and please share me your logic because of this issue i also stuck in my project but i am using MAX30100 sensor instade of HC-05 .
please help me
@robertomaster Hi, would you mind sharing a copy of your code with me too? I am having the same issue. Thank you in advance.

Hi, I'm sended you a mail with the code. But I attach the ZIP file with my logic.
Greetings.
I solved this problem with this lines in the loop.
if (millis() - tsLastReport1 >= 75) {
tsLastReport1 = millis();
pox.update();
}
