How To Scan for Specific BLEs

Syahmul Aziz Mohd Mursalin

Hi,

I am running an Arduino sketch that is based on HostTestApp project. The reference source codes can be found here.

I have 2 questions here.

1. GAPCentralRole_StartDiscovery(), list all devices discovered. However, how do I make it in such away that it only discover a list of BLE devices, based on MAC address instead of all?

2. Right now, I can only only extract MAC addresses after discovery. I have no idea on how do you extract other data like RSSI or what other data that can be extracted?

Thank you in advance,

I browsed through the APIs at http://ideafind.cn/api/GAPCentralhtml/d2/d93/structgap_dev_disc_req__t.html#a4499a0216342a1af81045616c5886778

But still, I don't see how do you configure the white list, as in specify the MAC addresses to filter.

I hope that someone is reading my question. It has been quite some time.

After lots of reading, I figured out that it is possible to use this function "LE_Add_Device_To_White_List"

However, I have no idea on how do you actually use this? Can someone point out my mistake? I wrote a short function below,

bStatus_t GAP_AddWhiteList() {
    return LE_Add_Device_To_White_List(0x00, 0x20CD39856D0D);
}

And then, when I compile my sketch on arduino, I get this error.

"error: 'LE_Add_Device_To_White_List' was not declared in this scope"
