No reviews on PRs
Becker Markus
Hi Zephyr team,
I have had PRs to Zephyr that have been reviewed immediately and got merged rather quickly. Some PRs however are not getting a review although (or because) there are many reviewers assigned. What is the process to trigger reviews on PRs that have been around for some time with reviewers assigned, but no reviews happening?
According to https://docs.zephyrproject.org/latest/contribute/index.html#pull-requests-and-issues it’s to bring up the topic on the mailing list.
Specifically, the PRs in questions https://github.com/zephyrproject-rtos/zephyr/pull/26193 https://github.com/zephyrproject-rtos/zephyr/pull/25627
BR, Markus

Re: Measuring LiPo on Adafruit nRF52 Feather
Peter A. Bigot
Look at samples/boards/nrf/battery, and boards/arm/thingy52_nrf52832/thingy52_nrf52832.dts which adds the voltage-divider compatible that describes the circuit connected to the ADC input. You'll need a similar node with the resistances specific to your board.

Measuring LiPo on Adafruit nRF52 Feather
Tomas McGuinness <tomas@...>
Hello,
I'm quite new to Zephyr, and I have a question related to the nRF52 Adafruit Feather.
As I understand it, this board gives you the ability to measure the voltage on the connected LiPo battery using GPIO 31 (A7).
For a small sensor project, I would like to use this measurement to report on battery level, but I cannot find any guidance on how I might read this pin's value?
Are there any examples you would recommend I take a look at? Any help would be very much appreciated!
Regards,
Tom

Re: Bluetooth mesh and Central role simultaneously

Hi Andreas,

No, I don’t think that combination would make sense. One option I forgot to mention is the bt_mesh_suspend() & bt_mesh_resume() APIs. You could try suspending mesh operations (advertising & scanning) for the duration of performing what you need in central
role, and then calling bt_mesh_resume() again. The effect will basically be the same as taking the mesh node out of range from the mesh network for that duration.

Re: Bluetooth mesh and Central role simultaneously
#bluetoothmesh
#bluetooth
Hi Johan,
thank you very much for your help in that matter. I am aware of the reduced scanning time for the mesh. It’s just that in my scenario the mesh is running all day long, and occasionally some BLE smartphone touches the device and then I need that fast ad-hoc connection.
With saying “LPN nodes are an exception”: do you think that the targeted coexistence with BLE Central role could be possible with a LowPower node?
I understand that we will not have a solution for my scenario short-term, so I might really have to think about using two controllers to get started. Overall I am quite impressed about the status of the BLE implementations in Zephyr and am looking forward to the next steps.
Best wishes, Andreas

Re: Zephyr HCI Mesh Support

However, BlueZ doesn’t require or even support them, so this should be a non-issue, meaning you should be able to use BlueZ (and its mesh stack) just fine with the Zephyr controller. Johan

Hi Andreas,
On 11. Jun 2020, at 11.37, Andreas <andreas.schmidt@...> wrote:
There’s nothing in the standard that prohibits it, but it will reduce the efficiency of the mesh network. The mesh advertising bearer is designed in such a way that assumes the nodes to be scanning as close as possible to 100% duty cycle (LPN nodes are
an exception). Any connections that you do will reduce the time the controller can spend scanning, and hence reduce the duty cycle.
Currently the Zephyr mesh stack is designed so that it assumes ownership of the advertising and scanning operations, which is why you’ll easily get conflicts and errors if you try to do those yourself. We do have plans to improve this co-existence with
the help of multiple advertising instances, but we don’t yet have support for this in the native Zephyr controller (AFAIK). That still wouldn’t help with the central role though, and for that we have plans to introduce HCI-extensions so that the controller
would be aware of Mesh-specific scanning and legacy scanning. However, I don’t think there’s any timeline or commitment to getting it done.
To implement what you need with the current stack, and without compromising the efficiency of the mesh network, I’d suggest to consider a HW setup where you have two controllers: one dedicated for mesh and another for the central role.

Zephyr HCI Mesh Support
Vivek Rajpara <vivek.rajpara@...>
Hello,
We are looking for the solution where we need to use Meshctl on Linux host and control the Zephyr based BT with it, can you please let us know if this support is enabled in Zephyr or not? Looking forward to hearing from you as it is a crucial design factor for us. Below is our setup nrf52840(as BT HCI controller) + Arm processor with Linux (we are using bluez 5.50 meshctl tool) I can see BT_HCI_MESH_EXT config, but it can't be enabled from menuconfig, I tried to enable it in project configuration but still, I can't send any command from meshctl to zephyr yet. Thanks in advance.
