Unable to connect more than one node.

[asprakash]

I am evaluating this single channel gateway even it is deprecated. Its still looking good for learning LoRa components.

I am using RPI as gateway and used two SX1276 transreceivers with 868Mhz freq. I can only connect with one node and unable to connect second node. I also tried the suspend mode once the data is transfered, but it wont work. I can able to connect second node only when I disconnect/poweroff the first node. Here I assumed that I can connect more than one node and transfer datas (one by one) in this single channel gateway. Some one help me to connect more than one node with single channel gateway.

TIA.
