No I don't see a problem with your parameters.

Could you send your full project showing the problem so I can test here ?

Oh, did I say connect to slave device? Sorry, I meant my device is able to connect to a Central device as a peripheral, while getting error when trying to connect to a Peripheral as a master. You're right, I could advertise and get connected as peripheral. Only Central connection fails.

nrf51-ble-driver_win_0.5.0 never worked for me.

So, you think that with the parameters that I supplied for sd_ble_init and sd_ble_gap_connect look OK for establishing an application that works as Central and Peripheral simultaneously?? I wonder what I am doing wrong here...

I don't see any issue with the parameters you provide.

Could you clarify what you meant in " am able to enumerate ports, connect to slave devices etc". What is "connect to slave device" ?

I assume that you can:

Scan for advertising packet
Advertise as a advertiser and get connected as a peripheral ?

I saw that you have also tested with the nrf51-ble-driver_win_0.5.0, do you have the same issue when testing with the examples come with that driver ?

@Hung Bui, Here are the connection and scan parameters passed to sd_ble_gap_connect(). I have checked the examples that you pointed out. I am not using Python. I am using C++ and am able to enumerate ports, connect to slave devices etc. Heart rate collector example seems to be using Central role. However, I failed to see what I am doing wrong comparing that example to mine.

ble_gap_scan_params_t   sp;
ble_gap_conn_params_t   cp;
ble_gap_addr_t *   addressToConnect = addressreceivedFromBLE_GAP_EVT_ADV_REPORT;

sp.selective = 0;
sp.active = 0; 
sp.interval = 50;
sp.window = 10;
sp.timeout = 1;

cp.min_conn_interval = 10;
cp.max_conn_interval = 10;
cp.slave_latency = 0;
cp.conn_sup_timeout = 1000;

//Connect to address we know from BLE_GAP_EVT_ADV_REPORT
err_code = sd_ble_gap_connect(adapter, addressToConnect, &sp, &cp);

Also, please let us know the parameters you used when calling sd_ble_gap_connect()

@Raja: Have you tried to test with some examples comes with the driver, for example these ?
