Re: HCI SPI - how to use

Bolivar, Marti


The hci_spi sample was originally upstreamed for use on the nRF51 chip
on the 96Boards Carbon board.

Please refer to the documentation for that board for more information.
You can refer to 96b_carbon and 96b_carbon_nrf51 board configurations as
a starting point for your own application.

My interest is in somehow making it possible for embedded Linux
distribution be able to use SPI transport for HCI. With all the chip
shortages of recent months and unsure about future I’m looking for a way to
get rid of relying on USB. Uart would be good but is already used + I need
more than 1, so besides USB I’ve only got SPI left but not sure how it’s
supposed to be tested. Guess I’m missing what the host should do, with USB
it’s clear.

Is there anybody who has prior experience with running the HCI SPI
