Is there any plan for Chibios to support STB32WB55?
https://www.st.com/en/microcontrollers/ ... tId=SS1961
It is probably one of the more exciting directions for STM32 family in years.
By integrating a separate processor and BT 5.0 stack, it is perfect for IoT and many consumer electronics.
I am looking to convert my current project to this chip, and would be very interested to hear if Chibios has plan for this chip family.
I would be happy to source some chips for you at my cost. Unfortunately there isn't a dev board out yet from ST.

Re: STM32WB55 support
Looks like ST does have a dev kit now.

If you are interested to look into WB55 support for HAL/Chibios, please pm me and i will send a kit over thanks.

Re: STM32WB55 support
Ciao,
I already have the hardware. I can surely create a port for this mcu but I do not know if I have enough room to manage ble right now.

Hello @RoccoMarco
Do you have any plan as to if ChibiOS will support the Bluetooth extension?

Re: STM32WB55 support
Hi,
Support would be possible but do not expect we re-do all the communication stacks, that is not in our perimeter. Is the M0 side independent or does it require support as well?

Hello Giovanni,
As I understand it the M0 is controlled by the wireless stack binary. Now I dont know if the licensing is happy with ChibiOS + STM32_WPAN. Any opinion on that?

Re: STM32WB55 support
I don't know their licensing terms, is this STM32_WPAN provided as a binary?
If it is not "linked" with the GPL SW then there should be no problems.
The device itself is a subset of an L4+, supporting it would be no problem.

Re: STM32WB55 support
Looks like its a binary yes: https://github.com/STMicroelectronics/S ... s_Binaries
This is the license: https://www.st.com/content/ccc/resource ... LA0044.txt
I suppose we could create some sort of HAL driver that interfaces with this library?

Re: STM32WB55 support
EDIT:
It looks like this is the header files that interface with the binary: https://github.com/STMicroelectronics/S ... STM32_WPAN
Looks like they are in the same license. So as the header files are compiled, is this a no go?

Re: STM32WB55 support
It depends on how the binary is used, is it a library linked with the GPL code or is it something that is flashed separately on the device like a different application on the same device?
If it is a separate binary and loaded/flashed separately then I believe there are no problems with GPL code.
