What difference is there between _hci, _spi and _uart examples?

[Ronny Vrijelinck]

For some of the examples i see different versions For example the ble_app_hts example It has a _hci, _spi and a _uart version In the documentation i don't find any info about these different versions What is the difference between them?

The ser_s132_hci, ser_s132_spi and ser_s132_uart projects are serialization projects. This is basically when you just want run the SoftDevice on one chip and controlling it with another chip running your application. hci, spi and uart are just the protocol the two chips communicate with. To read more about this you can go here: infocenter.nordicsemi.com/.../lib_serialization.html

For a normal project where you want to run everything on the same nRF5 chip, use the project in the s132 folder.
