I use sdk_9.0.0 and I have realized that there are only:
#define BLE_GAP_ROLE_INVALID 0x0 /**< Invalid Role. */
#define BLE_GAP_ROLE_PERIPH 0x1 /**< Peripheral Role. */
#define BLE_GAP_ROLE_CENTRAL 0x2 /**< Central Role. */
Suppose that I want to implement Broadcaster role with Broadcast mode and with advertising type ADV_NONCONN_IND, how should I then achieve it (using SD 130)? ble_advertising.h is only used for connectable advertising so I guess my implementation can only use files inside /sd130/headers?
What about Observer role and Observation procedure, how should that be achieved ?
