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.

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?

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 :)
