How to understand the data linker layer and physical layer in the Mesh network?

[lgs]

Hi There,

I have a question now. If I want to alter the frame format in the data linker, how do I do? 

I try to find the source code of the data linker layer in the Mesh SDK, I cannot find it. I just find the bearer layer. 

Could you help me answer the question?

Best regards,

I am not familiar with "control functions", can you elaborate a bit on what you mean?

Hi,

I mean some functions like in the transport layer in the TCP/IP model. It can establish a reliable connection between nodes.

Hi,

There are mechanisms in Bluetooth mesh for acknowledging messages, so that a sender is aware that a message has been received by the recipient. There are also parameters that can be set on the various nodes, related to message sending and relaying, for balancing throughput, reliability, etc of the network.

Bluetooth mesh is the best choice when there are small and infrequent messages intended for multiple recipients in a network of changing topology. If your throughput requirements are high, and the communication is over a fixed network from one node to another, then there might be other options that are better suited for your use case, such as a network based on BLE connections.

Hi,

Thanks. Basically, They are working between multi-node.
