Is there any reason not to implement an bluetooth-mesh BLOB Transfer sample?

[TOT0Ro]

When I first created the BLOB Transfer model, I had to analysis the DFU sample code because there was no BLOB Transfer model sample.

Is it possible for me to create a sample and contribute it to the sdk-nrf if possible?
If possible, can I create a sample of the ctl model and contribute to it as well? Or are there any restrictions?

I would be interested in seeing sample code using the BLOB Transfer Model.

Hi TOT0Ro,

Thank you for your interest in contributing to the SDK. We welcome it.

Our Mesh R&D team think that it might be better to add the BLOB Server and Client, with Shell control, to the DFU samples. What do you think about this approach?

Since R2 asked, below are the commands to evaluate BLOB models with the Mesh Shell sample. A Mesh colleague found it in his note. You will also need to enable the BLOB Server and Client models and Shell commands in the Mesh Shell sample first.

CONFIG_BT_MESH_SHELL_BLOB_SRV
CONFIG_BT_MESH_SHELL_BLOB_CLI
CONFIG_BT_MESH_SHELL_BLOB_IO_FLASH
CONFIG_BT_MESH_BLOB_CLI
CONFIG_BT_MESH_BLOB_SRV

# On BLOB sender shell:

mesh init
mesh cdb create 1234
mesh cdb show
mesh cdb app-key-add 0 0 
mesh prov local 0 1
mesh models cfg appkey add 0 0
mesh models cfg model app-bind 1 0 0x1400
mesh models cfg model app-bind 1 0 0x1401
mesh prov auth-method none
mesh prov remote-adv dddd0000000000000000000000000000 0 5 10
mesh target dst 5
mesh models cfg appkey add 0 0
mesh models cfg model app-bind 5 0 0x1401
mesh models cfg model app-bind 5 0 0x1400
mesh models blob cli target 0x05


# On BLOB receiver shell:
mesh models blob srv rx 0xac

# Then, on BLOB sender shell:
mesh models blob cli tx 0xac 1024 12 30

Hi Hieu,
Although any BLOB sample would be appreciated--and DFU is a very logical BLOB application---there are a number of requests in DevZone for a standalone sample that moves a large amount of data though a BLE mesh, unrelated to DFU.

Could the new DFU sample have the BLOB code in a separate file and a walkthough doc be written to show how BLOB works?

Hi rick.rarey,

I cannot make any promise, but I will relay the interest to our R&D team

Hi Hieu,

I have not used Shell control ever, but it sounds good. I can try it.

What do you think would be a good feature for the BLOB Transfer sample? I would like to suggest a very simple feature, like printing just the data stream.
