Hi.
Unfortunately, we don’t have any tutorial about that, and we don’t have one TFMini Plus to experiment with 🙁
I’ve found this library for arduino: https://github.com/budryerson/TFMini-Plus
I’m not sure if it is compatible with the ESP32. You can try uploading the example code and see if it works.

Thank you Sara,
unfortunately the Arduino library doesn’t work for ESP 32.

Hi Manuel,

I don’t have a TFMini Plus and I’ve never used it… nevertheless, what’s your problem? Is it just a problem with the serial bus connection?

In which case, you should know that the ESP32 has 3 hardware serial UART buses. You are free to use the UART2 bus which will not conflict with the microcontroller functions:

#define RX2_PIN 16
#define TX2_PIN 17

void setup() {
    //          baud rate  protocol
    //              v         v
    Serial2.begin(921600, SERIAL_8N1, RX2_PIN, TX2_PIN);
}

Hopefully your problem isn’t somewhere else.
Otherwise I’m afraid I can’t help you as I don’t have a LIDAR at my disposal :-/

Hi Manuel, Stéphane is right.
You probably need to use Serial2 to use the ESP32 serial pins and make it compatible with the ESP32

Thank you Steph and Sara Santos !
It was a problem with the serial bus pins, it was useful to define the pins.

Great!
I’m glad it’s solved.
I’ll mark this issue as resolved. If you need further help, you just need to open a new question in our forum.

Sara
