Bluetooth: HCI low power UART working as peripheral and central at the same time

[mjaszczykowski]

Dear Nordic,

We wonder if it is possible to connect to the BLE side of nRf9160dk using the LTE BLE Gateway sample.

Hi mjaszczykowski,

It is possible. The HCI applications simply include the Bluetooth Controller and expose an HCI interface, according to the Bluetooth spec.

You can enable Peripheral mode by setting these Kconfigs and all their dependencies to the suitable values:

On both the nRF9160 Bluetooth host and nRF52840 with Bluetooth Controller + HCI:

CONFIG_BT_PERIPHERAL
CONFIG_BT_MAX_CONN 

On only the nRF52840 Bluetooth Controller + HCI:

CONFIG_BT_CTLR_SDC_PERIPHERAL_COUNT
