Damaged Board?

PostPosted: Sun Aug 18, 2019 4:13 am

Hello everyone,
I bought an esp8266 01 and tried to upload code to it (blink and mail sending....) but they didn't work.
I tried to send AT commands, didn't work.
I tried uploading a new Espressif firmware and erasing the existing one, both failed.
There are errors about packet header. I am using Arduino Uno (serial converter).
Is the board damaged? Can I still use it? Is Rx connected to Rx and Tx to Tx or Rx to Tx and Tx to Rx? Anyone knows a good tutorial or can help me? Please let me know.
Thank you.
