nrf51822 central scan start & stop

[L.B.]

Hello everyone,

I'm using a NRF51822 as a central device, I connect to a peripheral (NRF51822-based device), then I stop the scan. At a later time I initiate another scan but the scan fails to detect my device. I never get events.

So my question is - is it sufficient to just use the two functions

sd_ble_gap_scan_start(&m_scan_params);

and

sd_ble_gap_scan_stop();

or should I invoke something else in addition?

Regards

p.s. I'm sure my peripheral is still active because I can see it with NRFtoolbox.

Hi. 

We actually have an example to show how this can be done. 

If you take a look at the BLE Multi-link Example: 
The BLE Multi-link Central example application shows how one central can be connected to several peripherals simultaneously.

BLE Multi-link Central: You can find the source code and the project file of the example in the following folder: 
<InstallFolder>\examples\ble_central\ble_app_multilink_central

BLE Multi-link Peripheral: You can find the source code and the project file of the example in the following folder: 
<InstallFolder>\examples\ble_peripheral\ble_app_blinky

Best regards, 
Joakim Jakobsen.
