2- For this problem i have tried to clear rx buffer when i receive data but i can not clear the rx buffer. How can i clear lpuart rx buffer in Simulink and Arm Studio?

Hello,

I think you can use a software approach to this problem. You can use delimiters in the message you send over uart and to read characters into a string one by one.

For example, if you want to send voltage, current and fault status over uart, you can format the message like this "voltage:10;current:1;fault:0" (using the ; as a delimiter). Then you can break the message like this:

Voltage:10
Current:1
Fault:0

Let me know if this approach helps you.
