https://devzone.nordicsemi.com/f/nordic-q-a/44980/nrf52-with-linuxI have some colleagues that are working on a project where they want to use the nRF52 as a general purpose IO processor alongside providing an BLE interface to a host Linux embedded SBC. Having worked with nRF52 for about 3 years, my suggestion wasen-USTelligent Community 13Mon, 18 Mar 2019 15:13:48 GMThttps://devzone.nordicsemi.com/thread/176782?ContentTypeID=1Mon, 18 Mar 2019 15:13:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:97f80867-dd72-49fe-ba39-e04cf164511dStian R&#248;ed Hafskjold<p>BlueZ is not running on the nRF52. BlueZ is the Linux <em>host</em> stack which runs on a Linux computer, talking to the Zephyr <em>controller</em> on the nRF52, over the HCI protocol.</p> <p>However, Zephyr can be run as both a controller AND host on the nRF52, similar to the SoftDevice. So you can run a BLE application without the need for an external host stack (i.e. BlueZ)</p><div style="clear:both;"></div>
