Hi, does somebody knows, is STM32WB55 support LE Codded or LE 1M or LE 2M?

Does this MCU supports Long range connectivity?

Hi.

1M and 2M - supported.

LE coded - NOT supported.

Hi Vyacheslav,

thanks a lot for the answer! Can you let me know, where I can find this information in original docs from STM32?

Do you know, does ST plans to support LE coded in future?

[Vyacheslav]

Only indirectly in AN5270 "STM32WB BLE wireless interface".

Open the document and search, for example, "LE coded".

Directly, unfortunately, nowhere written and I don't know what a plans to support this 🙂

I am not an STM employee, and they practically do not answer questions related to wireless technologies.

Regards,

Vyacheslav.

Ok, got you,

thanks for support! Lets see - maybe they will answer. If not - will try to contact them not by community.

Try it.

I did a ticket about DLE, but they didn’t even watch it. It's been 3 months, it is still open.

Maybe you are lucky 🙂

Hi, I got an answer from ST Support,

according to https://www.st.com/content/ccc/resource/technical/document/application_note/group1/25/56/53/7b/a0/17/47/c8/DM00571230/files/DM00571230.pdf/jcr:content/translations/en.DM00571230.pdf

page 4:

0x01: The transmitter PHY for the connection is LE 1M

0x02: The transmitter PHY for the connection is LE 2M

0x03: The transmitter PHY for the connection is LE coded (not supported by STM32WB) 

So, long range mode is not supported :(

Hi.

So I wrote about this, that according to AN5270 - LE coded does not supported :).
