Hello Everyone,

We are using LBEE5HY1MW on our customised imx7d sabre board. Recently for one of our tests I read the remote info for bluetooth through hcitool. The output of it is as shown:

As per the following link https://wireless.murata.com/type-1mw.html,

1MW supports Bluetooth 5.0 for which the LMP version should be 9.0? Then why does the hcitool info is receiving LMP version 0x7?

Could you please help me, if I am reading something wrong.

Thanks,
Asma

The device doesn't support any new feature in spec 5.0. It is only certificated with spec 5.0 on SIG.

Yes, it can support bluetooth beacons.

LBEE5HY1MW uses CYW43455 inside. It is qualified for Bluetooth 5.0 specification but doesn't support new feature in 5.0. You can claim the support for Bluetooth 5.0 of your end product. The LMP version will not influence the certification.

Hi @Owen_Zhang123 

I am not sure if I understand what you have replied.

What feature of 5.0 it does not support? Can you please elaborate on this please?

We are using this chip in our product which is involved in security related compliance, If it is not reporting 5.0 that will be an issue for us.

Is there any way, it can report 5.0 supported for LMP?

Thanks,

Asma
