Communication Between Device nodes.

[Chongchun Moon]

Hi, I am newbie at this field.

I have tried to configure network for communication between device nodes.

What i want to do is each device node has unique data( <30bytes) and each device node transfer unique data to another node automatically. It is kind of active tag.

Currently, It is configured that one of channels is TX only Master and one of channels is RX only slave on device, respectively.

It looks It works correctly.

Is it possible to use like above setting?

Is there any better idea?

Please comment with any idea.

Thanks.:)

Hi

How many nodes are you planning to have in your network?

Do you want all nodes to send data, and all nodes to receive this data?

Hello Petter,

It is possible many nodes(<10) exist in the network. However, Basically, Communication happens between two nodes.

And yes, All nodes need to send data and receive data. First problem is they don't know existence each other. That's why I have configured devices as above. Is it ridiculous? :)

After they recognizes existence of each other, They will send and receive what it wants to be transferred data.

Hi

You configuration is not reducilous. But I still don't understand what you want to do. You say you want communication between two nodes? Which two nodes?

Hi

This is one way of setting up a network of maximum 8 nodes, with unique device numbers. Using broadcast as data type.

Set up one channel for transmitting, for example channel 7, on each device. This should be a master transmit only channel, and the channel should be configured with the unique device number.

Set up seven channels for receiving, for example channel 0-6, on each device. These should be slave receive only channels, and have all parameters as wildcards (if you don't want anything else).

If you need to know which node is sending the data, the unique device number should be included in the message, either in in the payload in the standard data message format, or by using flagged extended data message format or legacy extended data message format.

Hope this covers what you were after, please let me know if anything is unclear or if there is anything else.

Hi Petter. I am currently trying to implement a network based on the above specifications that you described. But, I don't think that all the devices would be able to send data in this network. Since you are providing 1 master "transmit only" channel, only 1 device would be able to send data and the other devices will only receive data, through 7 slave "receive only" channels. Or, am I interpreting your answer differently? If so, please clarify.
