thak you very much.
i will prove.

My question is:
It is possible to send a string via send (msg)
If possible, could give me an example
thank you very much

And good afternoon.

@Boots33
Yes, thanks, that's what I want to do.
I'll prove it.

good day
I have this problem
I have a couple of nodes connected to the serial gateway (without a controller)
And the problem is that they cross the transmissions that they send me
(I need to have the measurements of the nodes separately)
the question is
It is possible to avoid the crossings of transmissions so that I get the data of node N first and then the next and so on.

I hope you can help me with this doubt
It's for a school project
Thank you.

Hi, hope you have a good day
i'm beginner in mysensors,
I hope you can help me, I have the problem in multi reboots in the sketch of gatewayserial and sometimes it freezes, hope you can help me.
this is the trouble.

o thank you, i will prove without that line

hello, i'm new in arduino and in das forum
and i have this error in code
i hope they can help me.
