I am trying to transmit serial data out of an Arduino in Simulink, see model below.
I am getting prompted with
The 'MATLABSystem' block cannot accept a signal of type string. A signal of type string is connected to 'Input Port 1' of block 'simulink_arduino_comm_test/Serial Transmit1'.
An error occurred while propagating data type 'string' from 'simulink_arduino_comm_test/To String1', output port 1.
Can I not transmit serial data?
If not, how can I generate a sentence with a start-character, checksum, and end-character without using a string or char array?

The example doesn't use the same blockset like shown in the question.
I'm currently struggling with the same problem:
how can I generate a sentence with a start-character, checksum, and end-character without using a string or char array?
