v2.4.0 merge window closes friday

Maureen Helm
 

Hi everyone,

This is a reminder that the v2.4.0 merge window for new features closes this Friday, 4 September. After that, only bug fixes and documentation will be merged until the final release is tagged, which is targeted for 25 September. Exceptions require TSC approval. New feature PRs may still be submitted while the merge window is closed, but please keep in mind that maintainers will have less time to review them during the release stabilization period.

 

Please add the v2.4.0 milestone to PRs that need to be included in the release, and do not wait until Friday to submit them.

https://github.com/zephyrproject-rtos/zephyr/wiki/Program-Management

https://github.com/zephyrproject-rtos/zephyr/pulls?q=is%3Apr+is%3Aopen+milestone%3Av2.4.0

 

Please try to help fix bugs, test release candidates, and write release notes to minimize the time the merge window is closed so we can all quickly get back to adding fun new things to Zephyr!

 

Thank you for your contributions!

 

Your v2.4.0 release manager,

Maureen

Hi Deepa,

 

From your question it seems you are using the nRF Connect SDK, and not vanilla Zephyr.

You should therefore direct your question to the Nordic DevZone instead:

Subject: [Zephyr-users] Reg: Installing and Running with windows laptop.

 

 

Hello team,

 

Greetings From Deepa. I need an manual  installation procedure and building, compiling and Running the zephyr -OS with my laptop for learning purpose. I browsed and compiled via cmd prompt, but still I need an Editor support for running this OS with nrf9160 controller. In addition to that, I  tried running with web browser as well. I also willing to run with an IDE(any IDE which supports for NC sdk) for creating my own projects and running with NC sdk.

 

Please, suggest some options along with sample projects running procedure at the earliest.

 

 

Thanks & Regards,

Good morning Torsten,

As a followup on yesterdays meeting I verified that one can use #include in a preinclude file with the IAR compiler, and that works fine, so a workaround for the limit of only one --preinclude directive, one could create a file that #include all the files and preinclude that.

Re: BLE Controller Core Spec 5.2 Power Control Feature

Chettimada, Vinayak Kariappa
 

>  I think it will integrate better with the new design but let me continue with the current master for the time being.

Current master has not accepted any new control procedure code except for bug fixes and conformance related changes since November 2019.

The strategy has been to restrain from any control procedure related changes in the current master and all focus be on the new work in the topic branch.

You should switch to integrating on the topic branch as the current control procedure code will be deleted in the very next release version after one release with new control procedure code merged.

Hi Vinayak

Thanks for sharing the sample Min used channels procedure. 

I had a quick look and the new design seems to be very elegant. Good to see the req/ack logic gone and using explicit states. I actually used explicit states in the draft LE PC feature implementation and tried to plug it in with the current master. I think it will integrate better with the new design but let me continue with the current master for the time being.

Khaled

I would not consider adding new control procedures to be ever straight forward considering the software requirements that needs to be addressed.

Yes, the overhaul is to introduce a design pattern, to address issues and to cover missing software requirements of currently implemented control procedures.

 

All controller development of BT adopted features happen in the open, you can always send draft PRs and solicit comments on github.

If you don’t have code/PR, you can start with a github issue to get discussions started.

 

An example of adding a simple control procedure could be this: https://github.com/zephyrproject-rtos/zephyr/commit/851f3631031189f0cd1d0ae976fe2be93ab5f386

Thanks Vinayak for your informative reply and addressing issues 1 to 4.

 

Glad to know that Zephyr link layer control procedure design is going  through a major overhaul. It is much needed. It was not a straight forward task to add the LE PC draft code. 

 

I am cleaning up the LE PC code and should make a PR as soon as it is ready. Can I share it without testing? Just the messages and message processing logic.

That said, you are welcome to send a draft PR with your implementation, reviewers will guide you towards contributions that can be reused towards the new design.

 

  1. Acceptable power reduction would have to be based on custom algorithm and specific to vendors.
  2. Reviewers and automated test cases should help you with LLCP data flow management
  3. Yes, you should reuse the already defined connection context and HAL interfaces that the dynamic Tx Power feature uses.
  4. Most development happens test driven, either using unit tests, babblesim, and manual using tests added in tests/Bluetooth/shell application. You can add your tests and test applications. Unit tests and babblesim are exercised in Zephyr CI on every PR submission.

 

You can start by involving reviewers early by sending in draft PRs.

Subject: [Zephyr-devel] BLE Controller Core Spec 5.2 Power Control Feature

 

Hello all,

 

I am working on the LE power control feature of Core Spec 5.2. I am almost 60-70% done defining the air-messages and the state machine within the llcp and he actions/behavior upon receiving PWR_CTRL_REQ/RSP or a related REJ. Also, not currently handling PWR_CTRL_IND and this should come later I guess. Feature still untested but it is in the pipeline.

 

Main issues now are:

1) Handling the APR (acceptable power reduction) in the PWR_CTRL_RSP

2) Insuring there are no leaks or any PWR_CTRL received pdu not released

3) Issuing command to change PHY TX power (I used the same method as in the host based TX power that this PR https://github.com/zephyrproject-rtos/zephyr/pull/19779 is addressing which seems to only change the connection TX power in the connection record and I guess the radio manager will then somehow use that to control the PHY?)

 

4) Overall testing. I need help here from the Zephyr Bluetooth developers.

 

Since this is my first potential contribution to Zephyr, I am following the contribution guidelines by posting in the mailing list to discuss the feature before proceeding with a pull request. 

 

Best regards,

 

Khaled Elsayed

RFC: remove w25qxxdv flash driver from Zephyr as of 2.4.0

Peter A. Bigot
 

The spi_flash_w25qxxdv driver has been superseded by the generic spi_nor driver for over a year. The only non-refactoring change to the W25Q driver in the last 18 months was done to support a backport to 1.14.

All devices supported by spi_flash_w25qxxdv driver are expected to be supported by the spi_nor driver, using the standard jedec,spi-nor devicetree compatible. No in-tree devicetree files make use of this driver.

To reduce confusion about which driver is expected to be used for JEDEC-standard SPI NOR serial flash memories pull request 27802 proposes to remove the redundant driver from Zephyr 2.4.  (It's not practical to deprecate a driver, and the existing one will work only for winbond,w25q16 if anything.

Please raise any concerns you have with this proposal as comments/reviews on the pull request.

Since this is my first potential contribution to Zephyr, I am following the contribution guidelines by posting in the mailing list to discuss the feature before proceeding with a pull request. 

 

Best regards,

Re: BLE Controller Core Spec 5.2 Power Control Feature

Chettimada, Vinayak Kariappa
 

Hi Khaled,

 

Currently the link layer is undergoing a major overhaul of the control procedure design. You can refer to the changes in the topic-ble-llcp branch.

 

That said, you are welcome to send a draft PR with your implementation, reviewers will guide you towards contributions that can be reused towards the new design.

 

  1. Acceptable power reduction would have to be based on custom algorithm and specific to vendors.
  2. Reviewers and automated test cases should help you with LLCP data flow management
  3. Yes, you should reuse the already defined connection context and HAL interfaces that the dynamic Tx Power feature uses.
  4. Most development happens test driven, either using unit tests, babblesim, and manual using tests added in tests/Bluetooth/shell application. You can add your tests and test applications. Unit tests and babblesim are exercised in Zephyr CI on every PR submission.

 

You can start by involving reviewers early by sending in draft PRs.

 

Regards,

Vinayak

Subject: [Zephyr-devel] BLE Controller Core Spec 5.2 Power Control Feature

 

Hello all,

 

I am working on the LE power control feature of Core Spec 5.2. I am almost 60-70% done defining the air-messages and the state machine within the llcp and he actions/behavior upon receiving PWR_CTRL_REQ/RSP or a related REJ. Also, not currently handling PWR_CTRL_IND and this should come later I guess. Feature still untested but it is in the pipeline.

 

Main issues now are:

1) Handling the APR (acceptable power reduction) in the PWR_CTRL_RSP

2) Insuring there are no leaks or any PWR_CTRL received pdu not released

3) Issuing command to change PHY TX power (I used the same method as in the host based TX power that this PR https://github.com/zephyrproject-rtos/zephyr/pull/19779 is addressing which seems to only change the connection TX power in the connection record and I guess the radio manager will then somehow use that to control the PHY?)

 

4) Overall testing. I need help here from the Zephyr Bluetooth developers.

 

Since this is my first potential contribution to Zephyr, I am following the contribution guidelines by posting in the mailing list to discuss the feature before proceeding with a pull request. 

 

Best regards,

 

Khaled Elsayed

Custom passkey not work. #ble #nrf52480

Hi,

I have problem using function bt_passkey_set(). Even if I use this function pairing use random number.
In application I use BT_SECURITY_L4 level. 

This is my config for Ble.

CONFIG_BT=y

CONFIG_BT_SMP=y

CONFIG_BT_SMP_SC_ONLY=y

CONFIG_BT_PERIPHERAL=y

CONFIG_BT_SETTINGS=y

CONFIG_BT_FIXED_PASSKEY=y

CONFIG_BT_MAX_CONN=2

CONFIG_BT_MAX_PAIRED=4

I use last master Zephyr repository for build.

Any idea?

Thank in advance.

Re: C++ user apps

Kim Bøndergaard
 


For application code it seems to be OK. You just have to enable it properly in your config:
Some of the configs I've been using:

CONFIG_STD_CPP11=y / CONFIG_STD_CPP14=y
CONFIG_NEWLIB_LIBC=y
CONFIG_CPLUSPLUS=y
CONFIG_LIB_CPLUSPLUS=y
CONFIG_RTTI=y

Beware of some of the pitfalls with e.g. exceptions.

Hi,

Is there any guidance about using C++ in Zephyr? Is it common / recommended?

Does anyone have a link to a previous discussion?
