Multiple Sonsors (integrated and BT) via MQTT
Hey Folks,

i really like your App, since i have several old smartphones lying around here that can be used as sensors.
For different applications/projects my demand is the following:
- Collecting various data with an ESP32 or Arduino and sending it to phyphox-app via BT
- Collecting various data from smartphone sensors
- Sending BT and smartphone sensor data via MQTT/Wi-Fi to an external server
- no data logging/saving in smartphone wanted since the logging and visualisation will be done on server

Now i'm facing following issues that i'd really appreciate your assistance:
- How can i can send more than one value from ESP32? i tried it with following sketch:
#include <phyphoxBle.h>

void setup() {
    PhyphoxBLE::start();                //Start the BLE server

void loop() {
    float randomNumber = random(0,100); //Generate random number in the range 0 to 100
    float sense = millis();
    PhyphoxBLE::write(randomNumber, sense);    //Send value to phyphox
    delay(1);                          //Shortly pause before repeating

but i only see the value 'randomNumber' in the app, not 'sense'

- from starting a new experiment in the app, i can only choose "Bluetooth experiment" or "simple experiment",
how can i create an experiment with both BT-data and integrated sensor data?
- how can i use the MQTT-functionality? unfortunately i haven't found anything about that topic yet. (i'm using app version 1.1.7)
- how can i read the sensor data, without logging them?

Best regards from way up north in Germany
