I had trouble connecting the v1 main board I have, with Putty or indeed any software.
It turns out you need to downgrade the driver, see explanation here:

Someting to do with the PL2303 chip being fake?
Anyway, you need version 3.3.2.105, downloadable here:

Perhaps something to add as a known issue.

Oh, good to know, thanks for reporting. Ouch, so fake chips... Good thing the esp8266 chips I include nowadays are Chinese in the first place

Something else I noticed with "Chinezium USB-TTL". They don't like Stop-Bit 2. Maybe it is driver related who knows. But when I set Stop-Bit as 1 it works fine ...even though the firmware code has 2.
/src/project/hwinit.cpp
Code: Select all
usart_set_baudrate(TERM_USART, USART_BAUDRATE);
usart_set_databits(TERM_USART, 8);
usart_set_stopbits(TERM_USART, USART_STOPBITS_2);

I have a Zigbee module here and for some reason it doesn't like 115200 baud rate and 2 stop bits, the "json" command returns partially corrupted data on the serial console, even when the receiver and transmitter are very close. Web interfaces don't work properly because of this. So I'm using 1 stop bit with 38400 baud rate.
