Update: New clue!

Actually, everything works fine if I decrease the baud rate to 9600 in MySensor.h (but not higher !).

Could it be possible that I have an alimentation issue? Do I need a decoupling capacitor?

Thanks for your comment.

Mine is this one : http://www.icstation.com/product_info.php?products_id=1393

Actually, I think all my wires are correct, because everything (sending temperature data from an arduino to another and logging through serial port) is working fine when I use "simpler" code, mixing Dallas and nRF24L01+ libraries.

I only have this behavior when trying to use MySensors code.

Hello,

I'm trying to setup a simple SerialGateway, using the following components:

• Arduino Pro Mini (3.3V, 8MHz)
• nRF 24L01+
• USB 2 TTL from icstation.com

But the serial output only print garbage strings, like

p{p{s{p{qt{‡ÁôÅ÷Áù@óôÁòôõð@ÃÏÍðÌÅôÅN
p{p{s{p{y{òÅÁÄz@ruuMruuMp@ó}ruuLÃ}sLô}sLðô}pLÌ}pz
ruu{ruu{s{p{s{
p{p{s{p{y{òÅÁÄz@ruuMruuMp@ó}ruuLÃ}sLô}sLðô}pLÌ}pz
ruu{ruu{s{p{s{
p{p{s{p{y{òÅÁÄz@ruuMruuMp@ó}ruuLÃ}sLô}sLðô}pLÌ}pz
ruu{ruu{s{p{s{

When I add another Arduino Uno with some sensor, it seems both are communicating. The sensor serial debug gives correct logs like:

send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,st=ok:
read: 255-1-0 s=255,c=3,t=3,pt=0,l=0:
Nb Sensors = 1
Temperature = 25.10
req node id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,st=ok:
read: 255-1-0 s=255,c=3,t=3,pt=0,l=0:
Nb Sensors = 1
Temperature = 25.00
req node id
send: 255-255-0-0 s=255,c=3,t=3,pt=0,l=0,st=ok:
read: 255-1-0 s=255,c=3,t=3,pt=0,l=0:

What could be the issue with my gateway? Both are 115200 bauds.

Please note that I'm a noob in both MySensors & Arduino
