i have uploaded the esp32 wifi code on my esp32 board and it is connected to my wifi and i can see the ip address as 192.168.0.72 when i open the apk and click on the ipp address to input the ipaddress http://192.168.0.72 i am getting Error 1101: Unable to get a response with the specified URL

Unfortunately, the Bluetooth app doesn't work. The Wi-Fi version also keeps crashing. I've tried setting up a second one, and this time I only get a short Wi-Fi connection, which it disconnects after a short time. I'm following the instructions exactly. Bluetooth: https://ibb.co/Df0HrbTF

Hi! Try to erase the Esp32 before uploading the sketch.

Unfortunately it still doesn't work. https://postimg.cc/xkV2PgY2

Hello, let's start with wifi app. Does the esp32 acquired the IP address? Could you please connect to Arduino IDE terminal and see the log? Set the baud rate to 115200

An update to the ESP32 library was faulty. I downgraded it and now it works. https://github.com/me-no-dev/ESPAsyncWebServer/issues/1455

Es funktioniert gut. Ich habe Pumpen mit 2/4mm Schlauch genommen. Da laufen pro Sekunde 0.7-0.8ml durch. Es wäre noch super, wenn man angeben könnte, was an der jeweiligen Pumpe dosiert wird.

It works well. I used pumps with 2/4mm tubing. 0.7-0.8ml run through per second. It would be great if you could specify what is being dosed at each pump.

Hallo,
ich würde das Projekt gern nachbauen, habe aber noch offene Fragen und hoffe auf eine Antwort.
Können die Pumpen in der App Kalibriert werden, oder ist die Fördermenge immer von der Einschaltzeit abhängig? Kann genau gewählt werden, welche Menge eingeführt wird?
Vielen Dank.

Hello, this version is working only on basis of time. So it's not possible to put the exact amount in ml to dose.
Instead, this particular version https://cults3d.com/en/3d-model/gadget/node-red-controlled-diy-peristaltic-pumps-project can calibrate and dose the amount in ml. But you need an additional Raspberry Pi Zero.
Cheers
