Hi all, I bought an ESP32 Dev Module from Amazon and have been trying to get the standard ros arduino publisher to work. When I try to connect using rosserial I get "Uable to sync" error. I have tried using different baud rates, 115200, 57600 and 9600 None of them worked. I clicked on the serial port monitor of the arduino IDE by mistake and saw this message keeps on repeating:

Not sure what to make out of the above error. What am I doing wrong? Thanks in advance.
