Inquiry — LwM2M support

[JongSeong_Kim]

Dear STMicroelectronics Support Team,

I previously submitted a request on [ Auguest 26, 2025] (case #[00242096]) and have not received a reply.
I am evaluating STM32 MCUs for an LwM2M client implementation and need clarification on ST’s official support.

Questions:

1. Does ST offer any MCU models with an official LwM2M stack or pre-integrated middleware?

2. Please provide package names, download links, and any long-term support information.

Please update the status of my open case and provide the requested technical references.

Best regards,

Name : Wilfred.kim (JongSeong.Kim)

Welcome @JongSeong_Kim, to the community!

As you can see from the Community Guidelines, e.g. article 2, the public community is not a support channel of STMicroelectronics, but primarily a user-driven forum for mutual assistance. The status of a ticket with the personal Online Support OLS can therefore only be updated there and not in the community.

However, to address your questions here:

1. LwM2M is supported by partners such as AVSystem, which provide tools like Anjay, who can answer all your questions. If by pre-integrated middleware you mean that this is already on the MCU when it is delivered, I must mention that there are no MCUs at all that contain any software other than a bootloader.
2. See 1, support from AVsystem

Hope that helps?

Regards
/Peter
