After implementing a throughput test for BLE using Nordic nrf52840 hardware and Zephyr 1.14-rc1, notice some curious behavior in data we are collecting. The test is to evaluate maximum throughput in a 1 to many and many to 1 scenario. Testing seems to show that when sending data from the central (client) to peripheral (server), the throughput performance is relatively balanced per connection but one peripheral seems to get less data and one peripheral get more than the others. In data flow from the peripherals to the central, it is much more unbalanced with one or two peripherals having all the throughput and the others having none.
The central to peripheral is 1:N where the central is a single point source. The many peripherals to central is an N:1 with many sources. In my case N is 1 up to 5, but would like to be greater. The overall aggregate throughput is constant, just not evenly distributed among the BLE devices or comm directions. Using DLE and 2M PHY and data is transferred using bt_gatt_write_without_response on client and bt_gatt_notify and the server. There doesn't seem to be any QOS but I would not have expected such unbalanced behavior. Any thoughts to why this is and how to diagnose/resolve to produce consistent and balanced throughput among the BLE devices? Do I have something misconfigured in my devices? Can share if that will help.

lightweight hash/MAC support
Jacob Morales Gonzalez <jacobinho86@...>
Hi, currently i am working on a benchmark project of the following light weight crypto hash and mac primitives:
Currently (as far as i know) there are baremetal software implementations for ATtiny Devices (https://link.springer.com/content/pdf/10.1007%2F978-3-642-37288-9_11.pdf), that ignore portability, and i think it is worth to integrate that functionality into the zephyr project, because it'll add light weight crypto protocols that are starting to be used in its fields of application:

Re: Atomic() vs k_sched_lock() vs irq_lock() vs k_mutex_lock()
Boie, Andrew P
You should be using the APIs in include/atomic.h
On arches that don't natively support atomic operations, these get implemented in terms of irq_lock()

We have an internal discussion about the recommended usage of the 4 methods mentioned in subjects, when the goal is to protect an assignment of a variable (u32 - any platform) within one task so it is not resulting in an invalid reading from a higher priority task.
Mutex'es are usually good since they only disturb the threads being involved in accessing the shared variable - but are they overkill in this case? irq_lock() sounds like something fast but effects the entire system k_sched_lock() is fast (according to the manual) but effects all threads as I see it.
atomic is probably a good option, but what's the efficiency on e.g. an ARM platform not natively supporting atomic's.
Any ideas or recommendation about when to use what solution?

Re: [Zephyr Main] WEST File Initialization Problem
Did you set up a toolchain as per https://docs.zephyrproject.org/latest/getting_started/index.html#set-up-a-toolchain?
If so, make sure you source zephyr-env.sh before attempting to build any sample code.
Note: you can also use west directly to build the sample code (since you invested some time to set it up correctly) – short version: $ source ./zephyr-env.sh $ west build –b qemu_x86 samples/hello_world And that’s it.

Thank you very much for your response. That problem is resolved by following your advised step. Moreover, now i was moving towards the HelloWorld example i received the following error.

Re: MCUMGR SMP implementations
Carles Cufi
Hi Rodrigo,
Assuming Board B is running Zephyr and not Linux, you can actually use LWM2M to update the firmware on Board B without having to write any additional code. The foundries.io folks use this model to update internet-connected boards. When it comes to SMP over IP, AFAIR it is actually supported on the open source project (mcumgr) but not in Zephyr. That said LWM2M is probably a better fit, since SMP uses a “push” model and you probably want a “pull” one for Board B, which will typically periodically poll the server for a firmware update.
You are right that there is no client available for SMP today written in C (that I know of). There’s only a desktop one written in Go (mcumgr) and iOS/Android libraries.

Hi all.
My company is developing two boards let's call them Board A and Board B for illustrating purpose. Board A is simple it has some sensors and it has a shell interface for communicating with the other one. Board B is the "gateway" and has Internet connectivity through the Cellular network. They had to be created separately.
We need to upgrade the firmware of both boards in the field. For now, Zephyr only supports FOTA over Bluetooth and Shell/UART, right? So I guess we'll need: 1 - to create a Shell SMP Client at Board B that will be able to upgrade the firmware of Board A using a version of the firmware received by the internet; 2 - to implement a different SMP Server at Board B to receive its own firmware by the Internet as well.
Do you have any start point, tips, something that could help here?
The future plan, after I made customs SMP Client and Server, is creating an SMP Server over Bluetooth Mesh. In another project, we will need that. Is anybody working with it already?
Thank you. Best regards, Rodrigo Peixoto Co-founder and Technical advisor

Re: [Zephyr Main] WEST File Initialization Problem
This is most likely what Marti said, you need to add ~/.local/bin to your PATH:
$ export PATH=$PATH:~/.local/bin
And try again.
If that works, you can make this change permanent via ~/.bashrc

After implementing a throughput test for BLE using #nrf52840 hardware and Zephyr 1.14-rc1, notice some curious behavior in data we are collecting. The test seems to show that sending data from the central (client) to peripheral (server) throughput performance is relatively balanced per connection but one peripheral seems to get little data and one peripheral get more. In data flow from the peripherals to the central, it is much more unbalanced with one or two peripherals having all the throughput and the others having none.
The central to peripheral is 1:N where the central is a single point source. The many peripherals to central is an N:1 with many sources. In my case N is 1 up to 5, but would like to be greater. The overall aggregate throughput is constant, just not evenly distributed among the BLE devices or comm directions. Using DLE and 2M PHY Any thoughts to why this behavior is present and how to diagnose/resolve to produce consistent and balanced throughput among the BLE devices? Do I have something misconfigured in my devices? Can share if that will help.
