Hi the mesh app currently does not keep track of the transaction IDs. Transaction IDs must be unique for each transaction so the app is using the sequence number as it is since the sequence number is also unique for each message. When implementing your app you may do it differently.

so why is nordic app using sequence nuber as transaction id when they send generic level messages?

here nordic app is receving sequence number from node and passing it as transaction id for GenericLevelSet.

How does it work?

final GenericLevelSet genericLevelSet = new GenericLevelSet(appKey, 
                mTransitionSteps, mTransitionStepResolution, delay, level, 
                node.getReceivedSequenceNumber());

Hi,

No, transaction ID is not the same as sequence number.

Transaction ID is 8 bit, sequence numbers are 24 bit.
