Moving from Slack to Discord

Carles Cufi
 

Hi all,

As voted during the TSC meeting on the 11th of August this year, the Zephyr Project is transitioning from Slack to Discord for real-time chat.
This transition will take place starting today, and the following steps have been taken already:

- Zephyr's new Discord server is up and running
- The new address for joining Zephyr's chat (i.e. Discord) is https://chat.zephyrproject.org/
- A subset of the existing Slack channels has been re-created in Discord. If you require additional channels to be created please contact the #discord channel in Discord itself
- An automated message will warn users on Slack about the transition so that they are informed.

Thanks,

Carles

Hi,
Latest version of the SDK can be found here:
https://github.com/zephyrproject-rtos/sdk-ng/releases/tag/v0.13.0
Please download and try things out and report any issues.
• general:
• Added support for ARC64. NOTE: GDB isn't currently supported for ARC64.
• CI/go.sh changes to make building MacOS and CI building easier.
• Various fixes for building/packaging on MacOS
• Added GitHub CI workflow to build MacOS x86_64 packages

• qemu:
• Updated to QEMU 6.0.0
• Added arc64 support. NOTE: this update ARC support replaces the machine (-M simhs) with (-M virt). This change will require updates to boards/arc/qemu_arc/board.cmake in Zephyr to match.
• Pull in fix from upstream for TFM: target/arm: Use correct SP in M-profile exception
• Pull in fixes from upstream for: hw/arm: Fix modelling of SSE-300 TCMs and SRAM
• gcc:
• Update to gcc 10.3 release
• Added support for ARC64
• Removed libgcc transactional memory clone registry support
• Fixed incorrect build specs for libstdc++ nano variant. The libstdc++ nano
variant, which is used with newlib-nano, is now built with -fno-exceptions to reduce compiled binary size.
• binutils:
• Updated to add support for ARC64

• newlib:
• Updated to add support for ARC64
• Added multithreading support
• Fix nano.spec file to pull in nano libraries.
• Set -mthumb-interwork for nano newlib builds to workaround at crosstool issue.
• crosstool-ng:
• sync with upstream. Upstream now supports newlib-nano so we drop our Zephyr specific updates. This also pulls in gcc-10.3 and initial support for ARC64.
• Fix stripping of newlib-nano libs
• yocto:
• Update to yocto 3.2.3 baseline. This is in prep to support building qemu-6.0.0

• openocd:
• Update to upstream 20210630 snapshot
Thanks to all that contributed fixes and enhancements to this version of the SDK.
Hi there.

Would it make sense to add documentation to the SDK installers?
I mean, given the reference to gcc 10.3 in the announcement,
I know where to find GCC documentation for it, but what about
binutils, the standard libraries and the other stuff included.
Surely applicable documentation can be found, but the manual
process of finding the right documentation is cumbersome
and error prone.
What do you think?

Re: Technical issue

Hi Sacha,
How have you configured it? Have you enabled and set the sample up to have the correct configuration options for your usecase? hcitool, hciconfig etc. are all deprecated tools, bluetoothctl is the single utility to use for Bluetooth when using BlueZ. Also BlueZ 5.50 is old, try on a newer build like 5.61.
Thanks,
Jamie

Error -EADDRNOTAVAIL when using bt_mesh_model_publish()

Omar Morceli
 

Hi
I am trying to publish some data using a vendor model, and I am getting error code -125  ( -EADDRNOTAVAIL).
Knowing the device was successfully configured and the key was bound correctly with no errors found in the logs.
Vendor model Library

Omar Morceli
 

Hi 
I have implemented a mesh network code based on the mesh sample (samples\bluetooth\mesh), I have added two vendor models and it works great when I tested it.
Now I'm trying to make these vendor models easily added to any bluetooth mesh code, so I have created a library (with headers files) .
and in the main code I added the vendor models using  BT_MESH_MODEL_VND_CB  and  all  callbacks and opcodes are defined in the library file.

The code gets built without any errors, the device gets provisioned with succes, but the models does't start publishing as they do in the simple code.

Is there anything I missed ?

thanks

Re: Zephyr technical question

Hi there,

the KConfig files contain the definitions of possible configuration options. You can then set them in your prj.conf like this:

CONFIG_BT_CTLR_TX_PWR_PLUS_5=y

Will it work for the hci_usb sample ?

Re: activating Low power mode with Bluetooth mesh sample

Trond Snekvik
 

Hi, 

To support low power mode, you must set CONFIG_BT_MESH_LOW_POWER=y. 
To make the device enter low power mode, either set CONFIG_BT_MESH_LPN_AUTO=y or call bt_mesh_lpn_set(true). 
Note that low power mode can only be enabled after provisioning completes.

Subject: [Zephyr-devel] activating Low power mode with Bluetooth mesh sample
 
Hi 

I am testing the bluetooth mesh sample  (samples\bluetooth\mesh) on a battery-powered device, I have to activate the low power mode in order to make it consume the least amount of power.
 
What's the best way to do that ?

Issue using lwm2m sample #lwm2m

Profitrolle
 

Hi all,
 
I'm trying to set up the LWM2M client sample with the ot overlay on a nrf52840 platform.

So far, I have set up the OTBR and I am able to ping the outside world (net ping 64:ff9b::8.8.8.8 is successful) from the nrf52840 (which seems to indicate that the OTBR is ok?).

Now that I try to set up the LESHAN server, I have no idea on how I should proceed to make the leshan and nrf communicate together. I have tried to launch the leshan server from my linux machine as well as from the RPI with the client endpoint set to nrf52840dk_nrf52840; nothings show up and I'm a bit stuck.

Any help or link to relevant information would be greatly appreciated!

Thanks in advance,

Arnaud

Re: Problem in Mesh network

Trond Snekvik
 

Hi,

Both buffer errors are a result of missing adv buffers. To minimize copying, both relay buffers and transport buffers are allocated from the advertising buffer pool, so that's the one that needs to increase to resolve this. 

If the total data rate for publications and relayed messages is higher than your advertiser's tx rate, increased buffer capacity will only get you so far though. Increasing the buffer count usually only helps with handling traffic spikes. Still, you'll definitely benefit from increasing it from 13 to something like 50 or 100.

Subject: [Zephyr-devel] Problem in Mesh network
 
Hi
There are four nodes in my bluetooth mesh network, each with two elements
The first element consists of four models
  1. BT_MESH_MODEL_CFG_SRV
  2. BT_MESH_MODEL_HEALTH_SRV
  3. BT_MESH_MODEL_ID_GEN_ONOFF_SRV
  4. BT_MESH_MODEL_ID_GEN_ONOFF_CLI
The second element consists of:
        (for three nodes) - two vendor models
        (for the fourth node) - three vendor models
The vendor models exchange periodic messages with ttl=2 and size of 45 Bytes with each other
messages period are between 10 and 30 seconds
Whenever I provision just two nodes, they work fine
After adding the third node, I receive some warnings 
      <wrn> bt_mesh_transport: Replay: src 0x00a3 dst 0xc001 seq 0x000e9c
      <wrn> bt_mesh_transport: Ignoring old SeqAuth 0x000adb
      <wrn> bt_mesh_transport: Duplicate SDU from src 0x000b
In all nodes, I receive these warnings when I add the fourth node (with the three vendor models)
      <wrn> bt_mesh_net: Unable to allocate loopback
      <wrn> bt_mesh_transport: No free slots for new incoming segmented messages
Afterwards, I receive the following errors
       <err> bt_mesh_net: Out of relay buffers
       <err> bt_mesh_transport: Out of network buffers
       <err> bt_mesh_access: Failed to publish (err -105)
and I sometimes  the node stops with this error : <err> os: Halting system


I made some changes to the configuration:
- BT_MESH_TX_SEG_MAX =10 
- BT_MESH_RX_SEG_MAX =10  
- BT_MESH_ADV_BUF_COUNT= 13 
- BT_MESH_SEG_BUFS=1024

However, I still get these warnings and errors?
