initial setup to view firmware logs

Postby unnakb » Fri Jun 08, 2018 10:44 am

I have a ESP32-WROOM-32D module. If I just connect to a FTDI UART-USB converter TTL-232R-3V3 cable, will I be able to see the debug logs from the default firmware that comes shipped with the module ?
The connection is
ESP32 TTL-232R-3V3
------- ----------------
GND - pin 1 GND
3V3 - pin 2 VCC
EN - pin 3 VCC
RXD0 - pin34 TXD
TXD0 - pin35 RXD

But I don't seem to see any outputs on com port terminal (putty) with 115200,1,8,N,XON/XOFF setting.
Any help, pl?

Do not use flow control.

I had to connect a 3.3V source to the 3V3 Pin of ESP32 instead of the Vcc of the USB serial converter TTL-232R_CABLE (which was 5V). After rectifying this blunder, the UART logging worked.
