Hi so I am trying to use serial receive block to receive serial from an arduino. I am trying to fun Simulink Serial Receive Block from instrument control tool box, when I run the model in hardware mode I get an error that the input needs numeric, char, logic. When I use regular simulation mode I can use the Serial.write() line to output serial. But once I run the model on hardware mode it does not work. Do I have to convert my serial into bytes and then use serial.write on hardware mode?

Hi Jarren
I understand that you are getting errors while using Simulink Serial Receive Block.
You may try converting the data into bytes and then use the Serial.write(). Serial.write() takes input as byte data.
To send data from Simulink to an Arduino over a serial connection, you can use the serial transmit block from the Instrument control toolbox. This block accepts input signals of various data types, including scalar numeric, etc.
Refer to MATLAB “Getting Started with Arduino ” documentation
I suggest you refer to this MathWorks documentation “Send and Receive Data Using Arduino Hardware”
