folny / esp32_metal_detector Goto Github PK

@folny Hi, I am wanting to try this, I have compiled the code and loaded up an ESP32-VROOM dev board to test. I have also loaded the Android app on my phone. It does connect via bluetooth ok, but then the app has an error and then the app stops ..

The error is:
Select list item: List index too large
Select list item: Attempt to get item number 5 of a list of length 4: (-99 200 65535 65535)

It seems the ESP32 is sending 5 items(battery V as well), but the android app only wants 4, is this correct. Maybe a mismatch of versions between android app and ESP32 code? Or will the code not work at all with a dev board in place of real board?

What is the status? Is it working at all? If so, what are the issues, I may be able to help ..

Cheers

I really like your project. But it is difficult for me to realize. Maybe you are ready to sold it for me?

I made this project. But I can't configure it. The firmware is uploaded to ESP32, the phone sees the bluetooth of the metal detector and connects ..
But I ran into a problem:

1. APK application does not work on Android 10. Writes that the program was created for an early version of Android.
2. No generation on IO26 ESP32. (transmitting signal)

Can you describe the setup process step by step?

What coil you use?
I have a coil "garrett" of 5 pins. How connect it?
Thanks.
