Hi, I am relatively new to using microcontrollers and I have been struggling for quite a while now to get the sensor to output even the slightest of data. After some debugging, i found out, that the code fails to verify the headers in the data, as represented below:

if(dat[i]==0x57&&dat[i+1]==0&&dat[i+2]==0xff&&dat[i+3]==0) {…} (this if-check does not pass)

This piece of code is taken from the example at the wiki here.

I am using the ESP32-WROOM-32D, of which the pinout sheet can be found here (pages 8,9). I am sure i have connected the RX,TX pins at the right places and i can read through Serial2.available() (I am using U2RXD, U2TXD), 256 bytes of data transmitted. Besides that, i think it may be important to include that, after monitoring Serial2.available() I'm seeing that after a while it gets stuck to 31 bytes and so, the program now refuses to pass the first check:

if(mySerial.available()>=32), where MySerial=Serial2

Any help would be greatly appreciated.
