Hi, Nordic staff.
I'm working with Central device using S132.
There is a peripheral device using S112 in Nordic. I didn't make this peripheral.
My question is that is it possible to discover above service and some characteristics uuid from S132 central?
If possible, can tell me how should I do?
Best regards.
Thank you. That's why I made it separately.
Is this the right way to do it?
But it hasn't been resolved...
What should I do... ...TT.
void MJR_c_on_db_disc_evt(ble_nus_c_t * p_ble_nus_c, ble_db_discovery_evt_t * p_evt)
{
ble_nus_c_evt_t nus_c_evt;
memset(&nus_c_evt,0,sizeof(ble_nus_c_evt_t));
ble_gatt_db_char_t * p_chars = p_evt->params.discovered_db.charateristics;
// Check if the NUS was discovered.
if ( (p_evt->evt_type == BLE_DB_DISCOVERY_COMPLETE)
&& (p_evt->params.discovered_db.srv_uuid.uuid == MJR_LE_SERVICE_UUID)
&& (p_evt->params.discovered_db.srv_uuid.type == NUS_SERVICE_UUID_TYPE))
{
uint32_t i;
for (i = 0; i < p_evt->params.discovered_db.char_count; i++)
{
switch (p_chars[i].characteristic.uuid.uuid)
{
case MJR_LE_NOTIFYCATION_UUID:
nus_c_evt.handles.nus_rx_handle = p_chars[i].characteristic.handle_value;
break;
case MJR_LE_WRITE_NO_RESPONSE_UUID:
nus_c_evt.handles.nus_tx_handle = p_chars[i].characteristic.handle_value;

break;

}

// ble_nus_c_on_db_disc_evt(&m_ble_nus_c, p_evt);

}
And your ble_evt_handler () should be ex:
