Serial write/read

Hi,

I try to create a seral connexion betwen 2 arduinos.

I connect

arduino 1 Tx to Arduino2 Rx
Arduino2 rX to Arduino1 tx

When I send from ardunino 1 a simple strng “A” like Serial.print(“A”) I would like to receive it in Arduino 2. Here is the problem : I receive something but not a string ! I get some numeric Value (65 as the ASCII code of A i guess) and then time to time 255 or 247 or 253.

Is there any way to transmit and receive simply the string and nothing else ??

Thanks

Seb

I believe you also need to connect the grounds of the two Arduinos to each other for successful operation.

Hi,

Please don’t cross post on the forums. Doing so results in duplicate replies from multiple people which is an inefficient use of resources. :slight_smile:

Thanks.

I’m sorry. Really. I thought I had post the 2nd message and a different forum. My mistake

That’s okay. :slight_smile:
