Hi guys, very nice to meet you all.
I have a question that bothers me for a while, and it's nice if you can help me.

I'm trying to connect the HC05 Bluetooth module\MAX232N\Arduino Leonardo together. I'm using pin0 & pin1 for the RX & TX for HC05 Bluetooth module, and I'm using pin10 & pin11 for the RX & TX for MAX232N, but I can't make it work, I can't get any data from RS232.
Is there anybody knows what's the issue or maybe has a clue?
Thank you very much!

Hello jiaqili

Welcome to the worldbest forum.

What is the task of the programme in real life?

We need some additional information.

Post your sketch, well formated, with well-tempered comments and in so called code tags "< code >" and a detailed circuit diagram to see how we can help.

Have a nice day and enjoy coding in C++.
