In the ble_evt handler, you will get a BLE_GAP_EVT_CONNECTED event when a connection has been established. You can then initiate the next connection from the handler.

Yes, I checked the two addresses. They are correct. It seems that the "connection request" (call from sd_ble_gap_connect(...) ) comes to fast. Do I have to wait until the first connection is established properly? If yes, how can I achive this "wait" function in a none blocking way?

Have you checked that peer_addr contains the correct address after you call memcpy?

Yes, MAX_CLIENTS is set to 8 --> and DEVICE_MANAGER_MAX_CONNECTIONS is set to MAX_CLIENTS. I can also see, that clientConnect(...) is called two times. But the depending DM_EVT_CONNECTION event in the device_manager_evt_handler is entered only once. So m_networkInfo.device[i].connected is set true for two known devices. This is done in a user menu, where the user can select peers he want to connect from a list. There also the ble scanning for new devices is done.

Can you upload more of your main file? MAX_CLIENTS is set > 1 and m_networkInfo.device[i].connected is set to 1 somewhere in your code?

Yes, I am using the device manager. DEVICE_MANAGER_MAX_CONNECTIONS is set to 8. So there should be no problem when connecting two different devices.

Are you using device manager? If so, what have you set DEVICE_MANAGER_MAX_CONNECTIONS to?

Hi Jorgen, I am using the SDK 8.1.0. I knwo it is a little bit old. But it is a big project that is already in production. So at the moment it is not possible to change the SDK.

Which SDK and softdevice versions are you using? Have you setup the central to allow concurrent connection to multiple peripherals?
