Hi and sorry for the late reply. I've been chatting with Waveshare directly through email and still could not find the issue; they told me to message their Sales team for a replacement…which is a tedious process, since they reply after about 3-4 days per email. I have ditched the esp for now and i have had problems with their software. The device still connects and the software receives data, but no matter what i try, the device always refuses to be recognized(which can be done though a button) and the data itself(as the waveshare assistant referred as) is “strange”. Here are the last logs i got from the software and sent through email.

The first log file referres to the attemps of me pressing the recognize button. “Changing the baudrate from 2000000 to <number>”, still have no idea why happens, since the baudrate is correctly set in the software. Funny thing is, when trying to match the requested baudrate(like 921600 written in the log), this happens.

…exactly the same thing. 

Sorry, the pinout sheet is here
