On your github page for espduino : https://github.com/tuanpmt/espduino,

How do I change the code to use the hardware serial port on my arduino??
I need the high speed and reliability that the hardware serial port provides.

Or if anyone else knows what change to make

Thanks

First, thanks for this firmware.

I'm trying to follow your instructions. I have the ESP8266 and FTDI232 connected to a Linux computer. When I run the line

Code: Select allesp8266/tools/esptool.py -p COM1 write_flash 0x00000 esp8266/release/0x00000.bin 0x40000 esp8266/release/0x40000.bin

I get this error:

Code: Select allTraceback (most recent call last):
  File "esp8266/tools/esptool.py", line 22, in <module>
    import serial
ImportError: No module named serial

I'm not sure how to fix this. Are we suppose to change COM1 to something else? Not very experienced with this.
