Yes. It is segmented by the SDK. It isn't the softdevice that does this, but the libraries in the SDK.

I am able to send 255 bytes and receive all bytes without loss from one node to another in one shot. I have not modified anything related to segmentation. I am using mesh sdk version 3 and nrf52840 dev boards. Does the softdevice automatically segment packets?

is it done automatically the segmentation because i could send 370 bytes now and i didn't do anything that have relation with segmentation

The application should partition the data if it is bigger than 37 bytes before sending and the end peer should accumulate it. This is same in Bluetooth LE and BLE Mesh.

Hi Susheel Nuguru,

What about the segmentation, when does it work when the payload is greater than 37bytes?

And is this size same for reply_status() as well

Hi,

1)Since Bluetooth Mesh (BTMesh) is built on BLE 4.0.

BTMesh works only on advertising barrier, meaning, that it makes use of only advertising packets to transfer data.

And the Min and Max payload (data) in advertising packet are 6 and 37 bytes, Also the snapshot from spec BLE v4.0 Vol6->PartB->2.3.1

.2) On the terminal yes, you can use commands or use RTT to print from your application.

Currently the nRF Mesh APP is a very good starting point that can be used to configure the Mesh network, but it cannot be used to send and sniff data. I am not sure if there are any other generic apps you can use for this.
