Assistance with BCF selection for FG4108E-S [EU]

I could not find the specific BCF file for this particular partner module for morsemicro on the git

i am aiming to use this module with morsemicro/halow component in ESP-IDF from its ESP component register, however, the git link provided in that readme does not contain BCF specific to FnLink 4108E-S module.

i am also confused which bcf (MM6108) to use for 4108E-S module.

I am attaching the link for the component registry here :

could anyone please suggest the BCF for this particular board? i am aiming to use it in EU band as i intend to use in India which has a license free band of 865 to 867mhz only.

Thank you in advance.

Hi @omumbare

FN-Link haven’t shared their BCF with us, which is why it is not available via our GitHub repository. We will try to reach out to them to see if they’re happy for us to distribute the BCF.

In the meantime you will need to contact fn-link for the BCF, as the module vendors need to tune the configuration specific to their module design.

hi @ajudge
i tried contacting FnLink multiple times, but recieved no reply from them at all. Is there any BCF i could remotely use?

Also i am exploring MM8108, i read it does not require specific SAW filters for each region, and one 8108 module can work for most of the regions with a range of different frequencies for example, same mm8108 module can work in USA as well as EU as well as AUS(maybe) and in India as well, no need to buy region specific mm8108 module like we used to do with mm6108 modules, which needed region specific SAW filters, hence different variants of modules.

Please correct me if i am wrong.

Unfortunately not. But it sounds like FNLink finally delivered!

This is accurate.
