Noise on pins 0 and 1 (TX RX)

Official Hardware Classic Yún
1

Hi there:

I am using EasyTransfer library

to communicate one Arduino Yun (transmitter) and one Arduino Nano (receiver).

The program works well communicating one Arduino Uno and the Arduino Nano. However, when I use it on the Yun it does not work.

I have used the scope to check the TX line on Uno and Yun. On Uno, the TX has no noise. On Yun it has so much noise that the Nano does not understand the communication.

I know this is a very general question... but...is this a general problem of Yun? What happens with pins 0 and 1 in Yun in comparison with Uno?

Thanks in advance

Noise on pins 0 and 1 is from ar9331, you can not use pins 0 and 1.

use SoftwareSerial Library instead of.

Not all pins on the Leonardo (Yun) support change interrupts, so only the following can be used for RX: 8, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI).

Thanks!

So I guess there is no restriction for TX... I mean whatever pin is OK.
