BLE Central and BLE Peripheral roles at a moment on nRF52832

Reported by Thanh Do:

Hi,

I have an application with BLE on Nordic nRF52832 with BLE Central and Peripheral at a moment.

• The config: CONFIG_BT=y CONFIG_BT_DEBUG_LOG=y CONFIG_BT_DEBUG_MONITOR=n CONFIG_BT_SMP=n CONFIG_BT_CENTRAL=y CONFIG_BT_GATT_CLIENT=y CONFIG_BT_MAX_CONN=32 CONFIG_BT_DEVICE_NAME="perph_name" CONFIG_BT_PERIPHERAL=y CONFIG_BT_CONN=y

• The application is working fine but I have a question. How to determine the connection which is connected to Central or Peripheral roles?
  Because when an another device connect to my device, both Central and Peripheral Connected Callback is actived.

I don't think Jira is the right place for questions (you should use the mailing list or IRC instead), however let me give you a quick answer anyway: you can use the bt_conn_get_info() API for this. The role member of the info struct will be BT_CONN_ROLE_MASTER when Zephyr is central and BT_CONN_ROLE_SLAVE when Zephyr is peripheral.
