Tfmini plus sends no messurments to arduino mrk gsm 1400

Hallo.
I have a problem with my tfmini plus liadr and my arduino mrk gsm 1400. This is my first arduino project so don't be surprised if i make silly mistakes. The Problem is that in the serial monitor I always get this:

Status: TIMEOUT
00 00 00 00 00 00 00 00
Firmware version: Z_Status: TIMEOUT
00 00 00 00 00 00 00 00
Data-Frame rate: ZwStatus: TIMEOUT
00 00 00 00 00 00 00 00
Status: HEADER
00 00 00 00 00 00 00 00
Status: HEADER
00 00 00 00 00 00 00 00

I connected the red wire of the tf mini plus to the 5v of the arduino, the black wire to the ground, the whit wire to tx pin14 and the green wire to pin13 rx.

and this is my code:

#include <LibPrintf.h>

/* File Name: TFMP_example.ino
 * Developer: Bud Ryerson
 * Inception: 29JAN2019
 * Last work: 19MAY2021

 * Description: Arduino sketch to test the Benewake TFMini Plus
 * time-of-flight Lidar ranging sensor using the TFMPlus library.

 * Default settings for the TFMini Plus are a 115200 serial baud rate
 * and a 100Hz measurement frame rate. The device will begin returning
 * measurement data right away:
 *   Distance in centimeters,
 *   Signal strength in arbitrary units,
 *   and an encoded number for Temperature in degrees centigrade.

 * Use the 'sendCommand()' to send commands and return a status code.
 * Commands are selected from the library's list of defined commands.
 * Parameters can be entered directly (115200, 250, etc) but for
 * safety, they should be chosen from the library's defined lists.

    delay(50);   // Loop delay to match the 20Hz data frame rate

    if( tfmP.getData( tfDist, tfFlux, tfTemp)) // Get data from the device.
    {
      printf( "Dist:%04icm ", tfDist);   // display distance,
      printf( "Flux:%05i ",   tfFlux);   // display signal strength/quality,
      printf( "Temp:%2i\°C",  tfTemp);   // display temperature,
      printf( "\r\n");                   // end-of-line.
    }
    else                  // If the command fails...
    {
      tfmP.printFrame();  // display the error and HEX dataa
    }
}

this is the example code from the tfmini plus library. I modified it a bit so that i get any output on the serial monitor.

I would appreciat any help

Did you remove the plastic film that covers the TFMiniP out of the box?

I did not remove the plastic cover with my first TFMiniP, it burned up. POOF!

no I didn't emediatly remove the plastic cover. I'am not sure if I did it before I applied corrent or if I did it after. But its possible that I have made the same mistake. Is there a way to find out if I made this mistake?

The TFMiniP I burnt up felt a little warm is what had me decide it was defective.

My TfminiP was also a little warm. Does the Tfminip get warm wen it runs properly? How much does the tempreture change wen the tfminip runs?

The TFMiniP that I have that works does not feel warm to the touch when in operation.
