Error in Arduino Cloud Web Editor

Projects Programming
1

Hi Experts, I am facing a problem in Arduino Cloud Sketch Web editor. The code is ending up with an error " 'SWSERIAL_8N1' was not declared in this scope". I am using the program for communicating to MODBUS meter. The library which I am using is ModbusRTU.h for modbus traffic. The same code is working properly in Arduino IDE, but when I configured the code in Arduino Cloud with the necessary changes, it is giving the error. I uploaded the same MODBUS library to Arduino Cloud Library Manager but still the same problem exists. What would have been the reason and what is wrong in my code? As far as I understand, no need to declare 'SWSERIAL_8N1 as it is taking from the library, am I right? kindly help me to resolve the problem.

The SWSERIAL_8N1 parameters and presumably others like it are used by the EspSoftwareSerial library but you are using the normal SoftwareSerial library

Which board are you using ?

3

Hi, I am using NODEMCU 1.

4

Have you tried the EspSoftwareSerial library ?

5

yes, I tried now, still the same issue

6

I have done some digging and experimentation

  • when you #include the espSoftwareSerial library it is referred to in the sketch as SoftWareSerial, which is confusing
  • using the SWSERIAL_8N1 parameter does not compile when you use an ESP8266 board
  • using the SWSERIAL_8N1 parameter does compile when you use an ESP32 board

This raises the question as to why you want to use SWSERIAL_8N1 in the first place

7

I am using the RS485 interface for communicating to the MODBUS devices. I am using the same code with the NODEMCU for reading the data from MODBUS Meters and MODBUS thermostats with the same code compiled through Arduino IDE. It is working perfectly. I really don't understand why the code is ending with the error. You can refer the library documentation from the below link.

8

The default is 8 bits, no parity, 1 stop bit so why do you need to specify it using SWSERIAL_8N1 ?

Please post the full error message that you get when you use SWSERIAL_8N1 so that we can see exactly where the error is occurring

What happens if you don't use the parameter ?

When I am using 'SoftwareSerial.h' library, I am getting only the error " 'SWSERIAL_8N1' was not declared in this scope" but when 'EspSoftwareSerial.h is using, I am getting the below errors:
