I’m using Arduino Uno and need to use software serial to communicate with other devices like modem or meter etc.
Using available single hardware serial, I’m able to connect to one device and function properly. Now I’m trying to use the software serial instead of the hardware one. I’m facing problem, as I can either send or receive only but not both on the softserial. Is there any way to have both send and receive? In my case, I need to send some request to the device (like Modbus) and expect the response from the same, which I’m unable to achieve with the softserial.
Could you please help me with some suggestion in correcting this and moving forward?
