Hi

I use 1DX(CYW4343W) module which is included BD MAC Address by Murata.

But all board indicate 43:43:A1:12:1F:AC of the MAC.

I found same case, but the solution is How to set the arbitrary address.

<https://community.cypress.com/message/32945#32945>

My question is how do I set BD MAC Address to the module assigned address.

Our design is:

Module:Murata 1DX (with BD Address tyep) (CYW4343W)

Linux :rel_imx_4.9.88_2.0.0_ga

Driver:meta-murata-wireles 4.14 mothra

Thanks!

Please ask Murata to create a case within our SFDC system as we normally do not exchange HCD files through the community.

The hcitools should help in changing the BD_ADDR

hciattach /dev/ttyS0 -t 10 bcm43xx 3000000 flow nosleep 11:22:33:44:55:66

Could you explain what you meant by module assigned address?

Thank you for your reply !

When we bought 1DX module from Murata , we could choose the type which is "with BD Address" or "without BD Address". And we bought "with BD Address" type.

So I think that Murata wrote unique BD Addrss to the module.

Does CYW4343W BT controller has Flash ROM or NVRAM that store BD Address ?  And can I uses the address by FMAC driver ?

Thanks.

I got a reply from Murata.

Murata wrote unique BD Addrss to OTP area.

And it needs a special *.hcd file which is using OTP BD Address.

Could you provide this hcd file ?

Thanks.

Murata themselves would need to provide the HCD file being referenced.

Thank you for your reply. but...

According to the reply from Murata,

The HCD file license holder is Cypress, so I should get the HCD file from Cypress.

Is it really ?
