Can I import 20721 Librarty(bt_hs_spk_lib) into CYBT-343026-01?

[shlim]

Hi~

I want to make a demo board with CYBT-3430260-01 EVAL board

I succeeded to import Audio headset application from CYW20706 BSP.

So, I can hear the music through CYBT-343026-01.

But  I have faced the issue for the button function like as volume up&down and play&pause.

I found the button library in CYW20721 BSP.

I wonder If I can import those library included 'bt_hs_spk_lib' from CYW20721 to CYBT-343026-01

Many Thanks

Hello @shlim 

20706 & 20721 uses different base Firmware. So there will be incompatible APIs. 

But I think button library for headset speaker should be portable. Can you try and let us know if you are facing any specific issues? 

Please note CYBT-343026 module will be having less GPIO pins comparing to base chips like 20706 / 20721.
