I didn't know that. Thanks :)

With S130 v1.0.0 it is not possible to reduce the number of peripheral connections a central can have. It is fixed to 3.

With S130 v2.0.0 and later this is configurable. S130 v2.0.0 is supported by SDK 11.0.0 and later.

Yes you're right. Of course I thought that. But our device should be display the animated pair, but it's a problem for display that I don't get a BLE_GAP_EVT_DISCONNECTED(ex. linkloss). If Nordic SUPPORT the limited count for peripheral, I don't consider anything. Doesn't the Nordic support the limited gap connection count? Of course, If Nordic doesn't support the limited count for peripheral, I should find other solution for my issue. Please let me know whether I can modify the limited count easily for peripheral connection.

Does it help if you call scan_start() when you get the BLE_GAP_EVT_DISCONNECTED event? When you get this event you are actually disconnected.

When the user press pair button, I call the below function.

void pair_press(void) { sd_ble_gap_disconnect(m_ble_nus_c.conn_handle, BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION);

scan_start(); }

So my device is connected as scan_start() and then "d i s c o n n e c t e d" as late sd_ble_gap_disconnect() response. (But sometimes, my device is disconnected and then connected, there is no problem in this case)

Don't you support limited count of the peripheral connection? Should I use only 3 peripherals for 1 center?

What do you mean by the signal response is sometimes late?

Yes. that's my point. I should start a scan after the first peripheral connection, because we have a scan button for supporting other device's connection by user request. But If I have one connection, the central should not make a one more connection. When I try to a gap disconnection, the signal response is sometimes late. So the peripheral is connecting state but the central is disconnecting state and scan state. That's why I want to limit connection count. Could you help me to solve the problem?

I'm not sure I understand. How you can limit the central to only connect to 1 peripheral? Not 3? If you don't scan you will not connect to anything. Are you starting a scan after you connect to the first peripheral?

Petter Myhre, I'm using nRF51_SDK_10.0.0_dc26b5e and S130's 1.0.0 verion. Actually, I want to reduce connection count between center and peripheral. I have 2 connected peripheral devices for 1 central device. I want to use one connected peripheral device with 1 cental device. Nordic can support the definition in central source of S130?

You want to do this to reduce the amount of RAM the SoftDevice needs? What SDK and SoftDevice version are you using?
