Arduino WB3S Software Serial

[ITstreet1]

Doing a few experiments with the WB3S module and Uno. How can I change default UART pins to, say, 6 and 7?

Can I work with WB3S using AT commands or in any other way, than the ones from your lib?

1. You can use the arduino's soft serial port.
   Example：

#include <TuyaWifi.h>
#include <SoftwareSerial.h>
SoftwareSerial mySerial= SoftwareSerial(5, 6);
TuyaWifi my_device(&mySerial);
...
void setup() 
{
...
  mySerial.begin(9600);
...
}
...

2.No support other commands

exit status 1

Compilation error: no matching function for call to 'TuyaWifi::TuyaWifi(SoftwareSerial*)'

The way TuyaWifi modifies the software serial port does not seem to work correctly

You can check if the version of the arduino library you are using is 0.0.3. In 0.0.3 he may not support SoftwareSerial.

I confirmed that the V0.0.3 I was using, SoftwareSerial could not be used, so I switched to HardwareSerial, but it would cause my chip to freeze. This is part of my code. When the button is pressed, hello will be output, but this code will Causing my chip to get stuck.
if (btn_W_State == LOW) {
mySerial.println("Hello luke"); // Send data through the serial port
} else {
.....

Here you've added some header files that aren't necessary, and there are some initializations that are wrong and incomplete. You can start by looking at the https://github.com/tuya/tuya-wifi-mcu-sdk-arduino-library/blob/master/examples/start/start.ino
