Is it possible to use a UART Wifi v2 and the USB as a serial port at the same time with a Seeeduino 4.2? It seems that when the WIFI is connected the USB serial is disabled, and only one serial is available. Perhaps with SoftwareSerial?
The reason I want is to have a printf-like debug on the serial port while developing code for the wifi. Is there another option to debug?
Hi,
Communicating with the same Serial Interface like UART is a little bit difficult if we have only one Hardware Serial UART better to use Software Serial . and it can work along with other Serial.
