Hei @shantaram ,

Theoretically you can do 1000+, so 25 should be pretty easy. Where exactly is the issue, can you give us a little more information.
Can’t they register for some reason, are the join requests not processed, etc.
Is it a configuration issue with the interface where you can not add them.
Do they authenticate, but the packets are not properly forwarded later, etc.

Thanks for the reply @Hobo

I am trying to connect 50 devices with RAK7244. when i connect 50 devices at a time 25 devices are not working well. they are disconnecting. but when i made 2 slots of 25 devices and checking independently its working well.

50 devices packet sent interval is 5 min

@shantaram

What do you mean 2 slots of 25 devices. Give us more details about the configuration.

Disconnect is not really a word that means anything in LoRaWan

What can happen is that a device expecting a response but not receiving one (due to congestion or misconfiguration or no infrastructure side software running) may eventually give up and start over, for example with a new OTAA join.

But it’s always the end device - the node - making the decision to give up.

So debugging should include not just what the nodes are doing, but why you/they decide that they are “disconnected”
