So are you basically sending a message from one node to the other without gateway, right?

[berkseo]

Yes, You are right. This is a simple example of sending and receiving messages between two nodes without the participation of the gateway.

[gohan]

It is one way communication only? Like a garage door/gate 433mhz remote

[berkseo]

@gohan You can send and receive messages in both directions. It all depends on how it will be implemented in the sketch. You can use more than two nodes. I would use it in case of a gateway failure. This will preserve the basic functionality of the device. For example, a light switch that is physically divided into two nodes. On one node, the touch panel on the other relay node controls the light. There can be a lot of use cases.

[gohan]

Could you please post the code for everyone?

[berkseo]

@gohan Of course, everything is simple there, uses one public function.

[gohan]

I know it is just to keep a reference here on the forum and for others less expert in programming that would like to see the actual code :wink:

ready, in the first post

[gohan]

you didn't put the "MY_PARENT_NO_ID 100" that I saw in the video: is it ok?

yes this is normal, this def is not needed. just forgot to delete when recording a video

two-way sending is done in the above application, this is also not in the video. you just asked about it earlier.
