How to programatically connect to an arbitrary peripheral device

Sorry, I see that I didn't add the snippet in my last reply. Sorry about that.

I was referring to the static char const m_target_periph_name (line 142 in the main.c). You can edit this to is_connect_per_addr instead for to connect to peripherals with a given address instead.

/**@brief Names which the central applications will scan for, and which will be advertised by the peripherals.
 *  if these are set to empty strings, the UUIDs defined below will be used
 */
static char const m_target_periph_name[] = "";      /**< If you want to connect to a peripheral using a given advertising name, type its name here. */
static bool is_connect_per_addr = false;            /**< If you want to connect to a peripheral with a given address, set this to true and put the correct address in the variable below. */

static ble_gap_addr_t const m_target_periph_addr =
{
    /* Possible values for addr_type:
       BLE_GAP_ADDR_TYPE_PUBLIC,
       BLE_GAP_ADDR_TYPE_RANDOM_STATIC,
       BLE_GAP_ADDR_TYPE_RANDOM_PRIVATE_RESOLVABLE,
       BLE_GAP_ADDR_TYPE_RANDOM_PRIVATE_NON_RESOLVABLE. */
    .addr_type = BLE_GAP_ADDR_TYPE_RANDOM_STATIC,
    .addr      = {0x8D, 0xFE, 0x23, 0x86, 0x77, 0xD9}
};

Best regards,

Simon

Hi Simon, which function are you referring to. I am looking at the example in the SDK 17 and do not see any function that connects to a peripheral.

Please check out the ble_app_hrs_c example project. The function below lets you decide whether you want to connect to a peripheral using a given advertising name or a given address, so you should be able to give your advertising device the necessary address to connect to it.

Best regards,

Simon
