Still having trouble getting it to work with version 0.68).
My esp is on com5 (CP2102 USB to UART bridge). When starting lualoader the right top shows red and no communication seems to work.
I changed my comport assignment to com2 using the device manager setting as you indicated.
Now Lualoader starts with green right top, but stll no communication.
The baudrate is correctly set at 9600.
Other com programs do correctly connect to the com5.
Any specific way to debug the lualoader connectivity ?
