Is I-CUBE-LRWAN has LBT ?

[NakornThree]

I used I-CUBE-LRWAN develop my sensor node. The problem is when a network have sensor node more than 15 node, sometime they can't transimit data to gateway. I found a recomend for other device that mcu have to eanble LBT to avoid the collision. Please help me,Can LBT solve the problem? I I-CUBE-LRWAN have LBT?

ALL the source code is provided, review it.

The Semtech chips provide for CAD (Channel Activity Detection)

Send less often.

De-synchronize your nodes.

Try to sense contention, and reduce/adapt.

Review college level network theory books if the concepts are unfamiliar.

Prior thread, perhaps provide more specific detail about the type and periodicity of the data transmission?
