Hello,
I am working on a project using the STM32WBA microcontroller and looking for a way to provide Wi-Fi connectivity in order to connect the system to a web server.
I've read in several places across ST's website that the STM32WBA series supports OpenThread Border Router (OTBR).
However, I couldn't find clear information on whether the STM32WBA can act as a standalone OTBR, or if it's limited to acting as a Radio Co-Processor (RCP) like some examples for the STM32WB series.
Does anyone know if it's possible to use the STM32WBA alone as a full OTBR? Or would I need to connect it to an external host that handles the Wi-Fi stack?
Any clarification or pointers to official documentation would be really appreciated!

Hello @aboabra and welcome to the ST Community.
A OpenThread border router (OTBR) is a specific router that connects a Thread network to other IPv6-based networks like Wi-Fi or Ethernet. Since the STM32WBA does not support Wi-Fi or Ethernet connection, so it can’t be a OTBR but it will need a host for IPv6-based network.
