Hallo,
ich würde gerne 2 Programme vereinen, die alleine bereits auf dem ESP32 funktionieren. Einmal ein Programm welches Daten in eine Influx DB sendet [1] (nach dem tut: ESP32: Getting Started with InfluxDB | Random Nerd Tutorials ) und einmal ein Programm, welches eine SPO2 Messung vornimmt. [2]

//**
* Secure Write Example code for InfluxDBClient library for Arduino
* Enter WiFi and InfluxDB parameters below
*
* Demonstrates connection to any InfluxDB instance accesible via:
* - unsecured http://...
* - secure https://... (appropriate certificate is required)
* - InfluxDB 2 Cloud at https://cloud2.influxdata.com/ (certificate is preconfigured)
* Measures signal level of the actually connected WiFi network
* This example demonstrates time handling, secure connection and measurement writing into InfluxDB
* Data can be immediately seen in a InfluxDB 2 Cloud UI - measurement wifi_status
*
* Complete project details at our blog: https://RandomNerdTutorials.com/

Nun habe ich den Code für die Influx DB angepasst, einmal die Lib eingebunden, neben dem Wifi Status habe ich noch einen SPO2 Wert hinzufügen wollen, er kompiliert auch korrekt, bleibt aber nach dem Senden des Wifi Wertes stecken:
