Thanks, Vikrant!

 

As you mentioned, I cd into “BlueZ 5.48/mesh”, but I can’t find any *.json in this folder on my Raspberry Pi3, below is the file list in the folder. Is there something I missed?

 

Regards,

Kai

Or you can directly execute

 

$meshctl -c bluez/mesh

 

In my case, it is 

 

$meshctl -c /home/vikrant/project/bluez/mesh

 

...(just for example)

Hi Kai,

Actually it is looking for json files which are available at blez_home/mesh.

Hi Vikrant,

Your suggestion is very useful about #meshctl, I’ve already downloaded BlueZ v5.48 and installed it on my Raspberry Pi3.

When I typed meshctl on the terminal, there is an error message shown: Local config directory not provided…

Do you know what configuration should be done if I want to run #meshctl?

 

Regards,

Kai

Hi Kai,

These are some useful links for you:

http://docs.zephyrproject.org/samples/boards/nrf52/mesh/onoff-app/README.html (for this you will need #meshctl as provisioner which is part of BlueZ 5.47  --> https://git.kernel.org/pub/scm/bluetooth/bluez.git/  )

https://devzone.nordicsemi.com/question/178532/zephyr-bluetooth-mesh-development/ (with this you can use Silicon Labs BluetoothMesh APP)

Hello,

I found a video on Youtube, https://www.youtube.com/watch?v=TwVwIjTX6SI  , Zephyr channel, it’s about 100 seconds.

I’m interested in how to set this demo up like:

• How many devices (micro:bit) do I need to prepare?
• What device would be the Provisioner?
• What firmware do I need to use? Under $ZEPHYR_BASE/sample or $ZEPHYR_BASE/test?

Thanks.

 

Regards,

Kai

Which application are you using? An unmodified tests/bluetooth/mesh_shell
should work directly. If you're using something else you might at least
want to take a look at the configuration of the mesh_shell app.

The first thing the shell prints is that it asks you to run "init"
before any other command. Since you haven't done that the "provision"
command doesn't do anything, and then you get EAGAIN (errno 11) when you
try to send a message, which is the error that the mesh stack returns
when you're not provisioned and try to send messages.

Hi there,

 

Yes, should be applicable to all those since they all call bt_att_create_pdu() which will block if there’s no buffers available.

Hello Carles,

            Many thanks for the information. Is this information is applicable to GATT indicate, write, read too?

Hi there,

 

Provided the peer does not initiate a GATT MTU Exchange, which would be handled automatically by the Zephyr BLE stack, you can simply call bt_gatt_notify() in a loop and from a thread while modifying the contents of the attribute in each iteration. When GATT runs out of buffers the the bt_gatt_notify() call will block until more are available, so you do not need to wait for an event like when using the SoftDevice.

Hello All,

          I have a question related to the one i asked last week. (https://lists.zephyrproject.org/pipermail/zephyr-users/2017-December/000915.html). But i will rephrase it and be more generic to what i am looking for now because that question was already answered and solution works too.

I have an Android client (BLE central) and zephyr OS based BLE device as peripheral (nRF device) transfer data over a custom profile. I am aware that in BLE we can transfer only 20 bytes at a time. And also there are possibilities to extend the data packet size or increase the ATT_MTU size based on negotiation. But for compatibility purposes, I will avoid using these techniques. I am also not using BLE mesh or nordic softdevice SDK.

In that case, what is the zephyr way of handling large data transfer over BLE.? Do we need to handle segmentation and reassembly in the application layer by our selves only ? or any callback events possible in case buffer is full during multi packet transmission so that we can handle this?.

 

I am searching if there is any solution similar to the accepted answer in this thread for nordic SDK: https://devzone.nordicsemi.com/question/1741/dealing-large-data-packets-through-ble/)

 

Any example or leads to this using zephyr is much appreciated. Thanks in advance.

Dhananjay GJ

Hi Johan,

I understand basics on configuration model. However, I'm trying to add app key, it results in following error

unable to send App Key add (error -11).

I face same issue trying to add net key. For your reference, I'm attaching snapshot of mesh shell

Are there any specific commands you're wondering about? You can get the
full list of them by typing "help". You'd e.g. start with provisioning
by typing "provision <network index> <unicast address>". The shell does
require basic knowledge of the configuration model, so I hope you can
explore the available commands and by experimenting get something
working. Each configuration model related shell command maps directly to
a configuration model message, so you'll need to look at the respective
specification section for each command for the details of its
parameters, etc.

Zephyr does not yet have provisioner support. You can only provision the
local node throught the mesh shell at the moment (since that does not
involve running the full provisioning protocol).
