Hello there,
I'm trying to implement a system in which only the whitelisted devices are allowed to scan but every device is allowed to send a connectino request.
As I've checked theadv_filt_policyinuser_config.hthere is such an option for the filtering policy. However, when I set this option, I'm not able to see my device and send a connection request. Could you please give me some instructions about how can I fix this issue and implement such an idea?
My goal is to indicate when a whitelisted device has sent a scan request.
Currently, I've based my work onble_app_securityexample of the sdk andscan_request_trackerexample.
Regards,
Hamid

Hi hamiddhosseini,
What is the SDK version that you are using? The WhiteListing has been added in the latest SDK release (version 6.0.14.1114). Please see app_easy_manage_wlist() API in the app_easy_whitelist.c.
Could you please indicate if you are using that API?
Thanks, PM_Dialog
I'm using SDK 6.0.14 and I have theapp_easy_manage_wlist()API.
However, I should be able to send a connection request to the device, regardless of the whitelist since advertisement filtering policy is set toADV_ALLOW_SCN_WLST_CON_ANY.Right now, I cannot send neither scan request nor connection request.
Furthermore, I have the following questions:
1- Isn't the device automatically added to the whitelist after pariring?
2- If it's not automatic, I should add the device to the whitelist after a successful pairing. Then later on I have to check if the device exists in the whitelist. However, whitelist operations do not include a search method. Therefore, How can I conduct a search in the whitelist?
Best regards,
Hamid
Hi Hamid,
When the app_easy_manage_wlist() is called, the device BD address is stored in the gap_ral_dev_info structure. Could you please share how you are using the app_easy_manage_wlist() API? Are you using any of the SDK examples?
Thanks, PM_Dialog
Hello there,
As it was mentioned before, I'm using ble_app_security example of the SDK and I've added the scan_request_track to it. These examples work together just fine and I can see the address of the devices who have sent a scan request.
At this point I want to trigger an event in case of a scan request from a white listed device. That being said, I have two options:
1- Change the adv_filt_policy to ADV_ALLOW_SCAN_WLST_CON_ANY; which should automatically stop non-whitelisted devices from sending scan requests. However, this change causes the device to stop advertising completely. It does not crash but there is no advertisement packets.
2- My second option is to allow every device to send a scan request and in the scan_request_cb, search for the devices in the whitelist. However, app_easy_manage_wlist() does not have any command for searching the whitelist and therefore I'm currently not using it.
Hi Hamid,
Could you please let me know if this question is related with this one?

Thanks, PM_Dialog
是的,我们的想法是相同的。我在讨论the first option, but since it seemed impossible, I started to implemetn the second option and I felt I need to start a new topic for that.
Hi Hamid,
Thanks for the clarification. So, let’s discuss this in your other forum ticket..
