Single Master / Multi Slave issue

[ajinkyaw]

Hi.
I want to use multi slave and one master connection.
My slaves are sending data to master after every 3 seconds.
Please guide me to use this lib in that condition.

That's actually more akin to multiple masters, and single slave. Multiple senders, and one receiver.

You have two options:

1. Just send the data and hope it gets through, or
2. Turn the system around and have the "master" request the data from each "slave" in turn.

Which you choose depends on the importance of the data. If you don't care if some data gets lost, but want it to be as light as possible, then option 1 could work. If you want it reliable, then you will have to use option 2. Personally I'd pick option 2 every time.

Simply have the master send a message to slave 1, saying "It's your turn". Slave 1 then sends its data. The master then sends the same message to slave 2, which then sends its data. Etc.

@majenkotech 👍 Thanks for the guidance (like everytime).
Can you suggest any particular library for Arduino to use.
