Subject: [Zephyr-devel] USB controller driver usb_dc_ep_write

 

Hi all,

I see many USB controller drivers implement usb_dc_ep_write function with one copy, copy the data (passed to usb_dc_ep_write) to one self’s buffer then do the transfer.

Do I need do this when implementing one new USB controller driver? Does the Zephyr USB stack limit the data (pass to usb_dc_ep_write) is in RAM?

The function prototype is as follow:

int usb_dc_ep_write(const u8_t ep, const u8_t *const data,

                  const u32_t data_len, u32_t *const ret_bytes)

 

Mark Wang

Thanks

Hi,

When could we expect that blemesh code will be usable in c++.
Most header files in zephyr are compatible with c++ but not ble mesh headers.
No #ifdef __cplusplus in headers.

Hi


There is a platform_whitelist in the sample.yaml file. In your case:

"platform_whitelist: frdm_k64f "


So you need this nxp board or have to port the sample to another board.

Re: CONFIG_BT_PRIVACY cannot be enabled with Hci_uart sample #nrf52832 #hci

Carles Cufi
 

Hi there,

 

If you are building the hci_uart then CONFIG_BT_PRIVACY is irrelevant because it’s only tied to the Host. What you need is CONFIG_BT_CTLR_PRIVACY, which enables privacy in the controller.

I think you can have "CONFIG_GPIO=n" in the

out of tree soc

mazaun@...
 

Hello,
I'm new to zephyr and yet working on examples. I like the modular structure of arch, toolchain, board and the use of cmake. Thats just  what I was tweaking around with. Also was thinking to use a rtos in my project. So zepyrproject just seems to hit the mark for me :)

I'm just trying to learn what is the best practice to add own modules in custom projects without changing the zephyr source tree. I learned how to add an out-of-tree board. Since I'm working with nios2 cores  I would need a method to add a soc too. I didn't find how to include a custom quartus/qsys project. What would be the best way to do?

Also concerning nios2 and qemu - how can I enable the float support in a project?

Best regards

I will try to make an example nios2  only (i.e. without support for the onchip ARM A9) - If there is a basic (free) core sample quartus project (DDR3 ram, cpu, uart) I could eventually start with.

Re: How to configure BLE Mesh FN and LPN?

Johan Hedberg
 

Hi Frank,

You need to have CONFIG_BT_MESH_FRIEND=y and/or CONFIG_BT_MESH_LOW_POWER=y enabled to get access to Friendship functionality. You might also want to look at the various BT_MESH_LPN_* and BT_MESH_FRIEND_* options found in subsys/bluetooth/host/mesh/Kconfig, however their default values should be enough to get you started.

As Friend there’s nothing special you need to do in your application, except enable the Kconfig option for it and make sure the corresponding Configuration Model State is enabled (either statically as the default value or by a configuration client).

As LPN you need to call bt_mesh_lpn_set(true) to go into Low Power mode. The reason why this is at runtime is to allow for devices that have variable power sources, e.g. an internal battery but may also be plugged to a stable external power source from time to time. The selection of Friend node happens automatically, but you can control the process by setting CONFIG_BT_MESH_LPN_RECV_WIN_FACTOR, CONFIG_BT_MESH_LPN_RSSI_FACTOR and CONFIG_BT_MESH_LPN_MIN_QUEUE_SIZE to desired values. To get a good understanding of these and how they influence the Friend Offer Delay calculation please refer to the Mesh specification (sections 3.6.6.3.1 and 3.6.6.4.1 in particular).

As for meshctl from BlueZ, I’m not sure if it has any Friendship features. It can definitely not act as a Friend or LPN since it is GATT-only (Friendship is an advertising-only concept in the current spec), but it might have Configuration Client support to toggle the Friend state at runtime (note: LPN has no matching Configuration Model state so you need to use the Zephyr API I mentioned earlier).

Hallo Zephyr Community, Johan,

So far I'm very impressed with the possibilities Zephyr and its BT Mesh framework already offers.
I recently played around successfully with the Generic On/Off sample application deployed on multiple nRF boards creating a BLE Mesh network.
I modified a little bit the code to have the use case I wanted to implement.

As far as I can see in the current Mesh code base v1.13 there is already support for implementing a Lower Power and a Friend node.

I'm just wondering how configuration is actually done, I would think a lower power node must say which is his friend node or vice versa? Maybe I missed it but I can't see anything implemented in the meshctl tool for doing this. And beside setting some defines in the code, is there additional coding needed.

Any help is very welcome,
Thanks in advance,
Best regards,

Re: Zephyr documentation

Carles Cufi
 

Hi Mayank,

 

A good start would be here: https://docs.zephyrproject.org/latest/devices/index.html

 

Then depending on what kind of driver you want to write my advice would be to look at an existing one and inspect the code in order to understand how it is implemented.
