the central can not find advertise package after disconnected;

[Jason Wen]

Hello Nordic Engineers:

SDK Verssion: nRF5_SDK_15.2.0_9412b96

IDE: Segger Embedded Studio

I use 1 Central and 5 Peripherals to build the network，they all can build the connection after power on.

Then I call the function sd_ble_gap_disconnect() on Central to disconnect with one Peripherals, the SoftDevice give me a reason code (0x16), it means that the host disconnect success.

and then I use the Android APP --- nRF_Connect, to do some scanning, it can find the advertise package in the air.

But, when I call the function sd_ble_gap_scan_start() on Central to do some scanning, the Central device can not find the advertise package, 

What causes this problem? Thank you~

Best Regards!

are you sure that the scan is actually started?

If you reset that Central, does it them see the advertising again?

Have you applied any filtering to the scanning?

Hello awneil,

thank you for your reply!

The problem has been sloved, the Central do some filtering after it get the scan response, when I remove the filtering, it works!  thank you~
