• Hello,
  
  I am working on a project where I connect a bluetooth speaker to an FPGA using the following component: https://digilent.com/shop/pmod-bt2-bluetooth-interface/
  
  I am working to configure this device, and I am wondering whether the RN42 can support Bluetooth audio?
  
  Thanks!

• According to the datasheet (https://ww1.microchip.com/downloads/en/DeviceDoc/rn-42-ds-v2.32r.pdf) of the onboard chip, it does not support any audio profiles in the built-in stack. However, it does appear that you may be able to implement your own profile using Host Controller Interface (HCI) mode? I don't know what that'd entail, but that would probably be the best bet.

• It's not recommended for new designs and has Bluetooth 2.1, which is ancient. It's safe to say that this is a futile endeavor. Is suggest getting a BM83. Or an nRF5340.
