Was looking at the Serial port bluetooth module datasheet and I notice PIO, SPI and USB connections. Is there any info available on how those can be used?
Hi Zotty,
The firmware of bluetooth module is only support Serial Port Protocol as described on the datasheet.
So the PIO, SPI and USB connections can not be used. (Some PIOs can be used as the instruction info).

Ah that’s too bad. Still the UART offers a lot of interesting projects, so I’m looking forward to including a couple in my next order 
Thank you for the quick and clear answer Icing!
