I´m in the first steps to built the BMS.
I have here a 8266MOD mini.
Tried to flash. Get the source compiled. The CH340 is visible in Windows10.
But finally the flash does not work.
A fatal error occurred: Failed to connect to ESP8266: Timed out waiting for packet header
The com is correct. Tried diffrend baud rates. ( also changed in the source and compiled new )…
Any suggestions or do I had bad luck and theres a defective chip?
