library not working

[beatricebruno]

Hello! I am currently trying to build a pulse oximeter with an arduino nano and the idea was to make it sand a notification on my phone whether the values were dangerous! So I used the code of the example on your website but arduino IDE does not recognize the library , so I can’t use the function to send the notification… Do you have any idea of why this is not working? Thank you in advance!

Hello, do you have any error log for me?

Basically we now think we figured out the library issue: we used the code in the example to create a library and we can now include it in the sketch. Can you confirm me this is the correct way to do it? Anyway now the problem is in the function "pushsafer", used in the void loop (). This is the message regarding the error:

C:\Users\maria\Desktop\polimi\informatica\arduino\app_push\app_push.ino: In function 'void loop()': app_push:112:43: error: no match for call to '(Pushsafer) (const char [14], WiFiClient&)' pushsafer(PushsaferKey, client);

So we assume the problem is either in the initialization of the function "pushsafer" or in the definition of the "client".

I'll send you the whole script, in case you need it:

include

include

include

include "MAX30100_PulseOximeter.h"

include

include //per wifiNINA

//#include //per pushsafer

// Pushsafer private or alias key

define PushsaferKey "XXXXXXXXXXXXX"

/WiFiClientSecure client;/ WiFiClient client; Pushsafer pushsafer(PushsaferKey, client);

LiquidCrystal lcd(13, 12, 11, 10, 9, 8);

define REPORTING_PERIOD_MS 1000

Hi,

a working example you will find here: https://github.com/appzer/pushsafer-arduino-library/blob/master/examples/esp8266/sendEvent/sendEvent.ino

I'm not a pro with arduino, so i can't help you. Please visit a Arduino Board there you will find help.
