STM32WB: Add HCI driver and enable BLE #14188

erwango · 2019-03-08T11:06:50Z

This series enable BLE on STM32WB.

It includes flash driver for persistent storage.

This is based on #16373

@erwango Have you tried it with samples/bluetooth/peripheral* ? I noticed that RF Performance is not that good , 30dBm ... 40dBm worse than nRF52 DK boards or FRDM-KW41Z.

@erwango Have you tried it with samples/bluetooth/peripheral* ? I noticed that RF Performance is not that good , 30dBm ... 40dBm worse than nRF52 DK boards or FRDM-KW41Z.

Yes I have tried it but didn't pay attention, I can see now that RF performance is not quite good indeed. Though, with other fw this is working correctly, so I may have messed up with SET_TX_POWER command. Let me have a check.

erwango · 2019-03-08T14:59:50Z

@jfischer-phytec-iot, it should be fixed now.

@erwango I tested few peripheral samples (e.g. peripheral and peripheral_sc_only). The connection was not successful, log part from peripheral sample:

erwango · 2019-03-12T15:41:14Z

@jfischer-phytec-iot, I have no issue on peripheral on my side. From what I understand, you've already managed to get it working once, is that a new status? Or is this in particular conditions?
Regarding peripheral_sc_only, I don't know if this requires specific support from controller stack, I'll check this and get back to you. Thanks for interest!

jfischer-no · 2019-03-13T13:58:16Z

From what I understand, you've already managed to get it working once, is that a new status? Or is this in particular conditions?

@erwango No, none of the peripheral samples work for me. Tested with nRF Connect and bluetoothctl on linux.

erwango · 2019-03-14T10:27:18Z

@erwango No, none of the peripheral samples work for me. Tested with nRF Connect and bluetoothctl on linux.

@jfischer-phytec-iot , ok. Well this is a big concern. Difference might come from the fact I use a pre mass market version. I'll get a board similar to yours and have a check.

erwango · 2019-03-14T15:41:23Z

@jfischer-phytec-iot, I had a check and got things working on the nucleo version you should own (ES MB1355C-01). And peripheral is working on both ST BLE Profile and nRF Connect. I don't know what could be the issue here.
@jhedberg, I think you own a nucleo_wb55rg yourself. Would you have time to do a simple peripheral test to see ig you face same issue as Johann?

jfischer-no · 2019-03-15T15:29:06Z

@erwango How do you flash your device? I tried it over MSD support only.

erwango · 2019-03-15T15:36:36Z

@jfischer-phytec-iot, yes I'm using mass storage as well. open-ocd support is upcoming but not yet available (AFAIK)

erwango · 2019-03-15T15:37:52Z

@jfischer-phytec-iot , I'm sorry to say that, but would you consider having a try with stm32cube package?

jfischer-no · 2019-03-15T15:59:55Z

I'm sorry to say that, but would you consider having a try with stm32cube package?

@erwango I have the package, but there is no way to build from command line?

erwango · 2019-03-15T16:05:58Z

@erwango I have the package, but there is no way to build from command line?

Using CubeMX Tool, you can generate a makefile. Though, it might not be direct.
Another option is I can generate send you a bin next week.

Ok, I just tested it 2 hours back and was working. Also has been tested by others successfully.
Might come from your M0 f/w version that require an upgrade.
We know there are nucleo_wb samples in the wild that hold a M0 f/w not compatible with use on Zephyr. Can I ask you to create a dedicated issue for this and I'll try to support you on that track?

Library providing hci driver for host/controller communication over shared RAM Origin: ST Microelectronics License: BSD-3-Clause URL: http://www.st.com/en/embedded-software/stm32cubewb.html Commit: 1.0.0 Purpose: Shared RAM driver for STM32WB Maintained-by: External Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>

stm32wb55rg is a dual core SoC (M4/M0) with a radio/protocol stack running on M0 core. M0 FW starts at flash address 0x80CB000. So flash size available to zephyr is 812K instead of 1M. Configure package size to reflect this (flash size is now 812K) and update MPU setting to exclude M0 FW. From MPU point of view, we set flash size to 512K since we should chose a size being a power of 2. If we consider there will be 2 images partitions in a FOTA scheme, 512 K is beyond image-0 and hence is sufficient to cover application image. Signed-off-by: Erwan Gouriou <erwan.gouriou@linaro.org>

mtuxpe · 2019-08-02T10:36:41Z

Hi there,
I am testing HCI driver using WB55Nucleo and also P-NUCLEO-WB55 USB dongle.
Sometimes BLE stack doesn't start on dngle but I don't know how to reproduce yet.
I am developing a custom peripheral application to connect with ST BLE Sensor mobile.
To flash dongle on linux you can use STM32Programmer:
https://community.st.com/s/question/0D50X00009q3X4jSAE/stm32cubeprogrammer-for-linux
Use the bash script described on stefan1.5521405057577783E12 post.
Anyway good job @erwango

Why can't I configure Bluetooth to find out who's going to direct it? Thank you, God. Have you ever met?

mtuxpe · 2019-09-20T12:09:23Z

Hi all,
Sometimes I got "Unhandled event" message while trying to connect to ST BLE Sensor Android app
On Zephyr side I am running BLE peripheral.
How to get detailed log ?

erwango · 2019-09-20T12:13:25Z

@mtuxpe, there's a dedicated application to trace HCI messages called monitor.
You can enable with CONFIG_BT_DEBUG_MONITOR=y, but this require to disable CONSOLE.
Then, you can get trace output over serial port with bluez btmon binary.

joerchan · 2019-09-20T13:07:39Z

@mtuxpe It's possible that the HCI driver sent an event through bt_recv_prio, when it should have sent it through bt_recv.

pavlohamov · 2019-10-01T08:30:53Z

@mtuxpe Hi. I've faces with the same issue. M0 firmware update - fixed the issue.

But now i'm seeing something strange with peripheral device. For all incoming connections the peer addresses are set to FF:FF:FF:FF:FF:FF, no matter how do i configure the BLE stack. for the Central role Addrs are ok. This issue block the secure connection.
@erwango Could you be so kid to point where to dig on this?

erwango · 2019-10-01T09:08:56Z

@pavlohamov @mtuxpe, if you're facing a particular issue, please raise a new issue and provide details on your set up so we can look at it in details. Current PR is merged, we won't do much here.

PoojaKatariya · 2019-10-05T04:33:08Z

Hello All,
I downloaded the BLE_TransparentMode.hex file on the Nucleo board using STM32CubeProgrammer. Once the board was loaded with that hex file I tried to connect it with STM32CubeMonitor-RF. But while I'm trying to connect the device I'm getting a prompt which says "Device under test not responding COM port closed".

Also, before having received your support I tried to run the default application which comes in built with the board along with ST BLE Sensor mobile application. Then I tried to write the code as per the You Tube tutorial on STM32WB55 OLT session by STMicroelectronics and after which I flashed
the board with stm32wb5x_BLE_Stack_fw.bin file as per one of the blogs on st.com. And now after having flashed the board; the blue tooth is not even getting detected on the sensor application.
Also, I am using STM32CubeIDE version 1.0.1 for all the development and not CubeMX platform.

Also I tried to boot up the Nucleo board right now as instructed in STM32WB package by:

a) Add a jumper between CN7.5 (VDD) and CN7.7 (BOOT0).
b) Power on the board via USB_USER and J2 jumper (USB_MCU)

Yet I am getting no results and facing the same issues as mentioned above.

erwango · 2019-10-05T20:01:09Z

@PoojaKatariya, this github project is dedicated to zephyr RTOS, which is not the default application delivered with the board or in Cube package.
You will get proper support for your issue on st.community.com.
