stm32wba : ble-802.15.4 concurrent mode integration #319

vtardy-st · 2025-10-17T08:05:33Z

Integration of the BLE-802.15.4 concurrent mode on stm32wba based on CubeWBA release 1.7.0

lib/stm32wba/README.rst

+
+   * Discard "static" implementation of ll_sys_bg_temperature_measurement_init to allow specific zephyr implementation
+      Impacted file: ll_sys_if.c
+                     ll_sys.h


It seems no real change here, we could revert ?

Hello @mathieuchopstm and @etienne-lms. Could you please have a look ?

mathieuchopstm

Some refinement needed but seems overall OK

lib/stm32wba/concurrent/Core/Inc/app_conf/app_conf.h

mathieuchopstm · 2025-11-12T09:33:42Z

lib/stm32wba/RF_Integration/Core/Inc/app_conf/app_conf.h

+#ifndef __ZEPHYR__
+#define RADIO_SW_LOW_INTR_PRIO              (15)           /* 2.4GHz RADIO low ISR priority */
+#else
+#define RADIO_SW_LOW_INTR_PRIO              (14)           /* 2.4GHz RADIO low ISR priority */
+#endif


Interrupt priority should come from DT anyways so I'm a bit surprised this is needed.

This interrupt priority constant is used in the link_layer_register_isr() function defined in zephyr\soc\st\stm32\stm32wbax\hci_if\linklayer_plat_adapt.c
If change should be done, it will be done in another PR

+#endif


If this header is visible from the Zephyr side, please use an approach similar to VCNano8000e stack instead: add private compile definition for the library only and gate these behind the private definition

Preferably with default case in switch/case instructions.

This code is heritated from CubeMx. Do you think this change is required ?

I can't mark conversations are resolved so I added 🚀 reaction to my own "resolved" messages instead.

@vtardy-st Please rebase

Combination of:

files duplicated depending on the use case (see comment)
functions adapted in place instead of in zephyr as it should actually be done (see comment)

makes the libraries more and more complex to review and maintain.
I don't think this is the right direction and approach should be reviewed.

lib/stm32wba/RF_Integration/Core/Inc/app_conf/app_conf.h

erwango

Thanks for the update. This is going in the good direction. I guess we can fix the remaining issue of Zephyr adaptation done in this repo instead of zephyr/ in a next repo.

Looking to https://github.com/vtardy-st/hal_stm32/blob/stm32wba_1_7_0_ble_802154_concurrent/lib/stm32wba/README.rst, there is indentation issues to fix to have the file readable, it would be nice to fix this (as an additional commit for issues that are not coming from current PR)

Otherwise LGTM

lib/stm32wba/README.rst

mathieuchopstm

Two minor nits + #319 (comment) left to address.

I think these are non-blocking though.

/* Enable AHB5ENR peripheral clock (bus CLK) */
