CCS/LAUNCHXL-CC2640R2: SimpleLink academy / BLE4.2 /Scanning and Advertising lab / Advertising Task 3 (Change Filter Policy) doesn't work

Hi Patrick,
I'm assigning this thread to an experts, stay tuned for an answer.

OK thank's a lot !

By the time I'm trying other labs.

I hope I will have some explanation.

Hello Patrick,
I could reproduce this issue on the first connect after I programmed the device. After I disconnect and try to connect the second time, then the filtering seems to work and the peripheral will ignore all scan requests and connection requests.
Can you confirm that it only works the first time you connect?

You need to enter the desired initiator BD address (central) into the white list to allow only that device to connect. In this case it is the phone Bluetooth address. It will also be listed in the peripheral log when you enter a connection. It makes no sense for a peripheral device to enter it's own address.

Hello Eirik

THank you for your reply.

I confirm that connection is possible only at first time. In fact it seems to be, but it's always the same situation, even if I register the right Bluetooth MAC address of my phone in the WHITELIST. With the "imple_peripheral" project modification explained in LAB Task3, the connection is just possible only one time and that for any central address.

Today I tried to follow agin this lab but the result is the same.

And I already looked at ressources links you sent me, but still found no explanation for that.

So, I continue investigations, and if you find more solution or ideas, be kind to let me know.

Best regards
Patrick

HI !

THank's for this reply.

I did what you suggested and here is what I could see.

At first run,that's OK, the Peripheral is invisible.

But in fact, it remains invisibe form my smartphone, regardless of any address I put !

At first I have set the Bluetooth Mac address which is indicated in phone settings.

As it didn't work, I tried to read and check the MAC address with Putty connected to the Peripheral, while suppressing the filtering policy.

So, I put this new address as filtering policy parameter, but the Peripheral still can't be seen.

Then I set again the initial advertising True to check again the Mac address, and this time, the displayed address in Putty was different...

Here is the portion of modified code :

It looks like if the address was changing depending upon the software I load into the Peripheral device. I never have the same.

I'm a bit disapointed.

Do y have explanation ?

Hi again Eirik !

Ok, thank's again.
I started to read the BLE5_Stack user's guide which describes the topic you told me. Unfortunately, as I'm an independant worker, I can't subscribe to the Bluetooth SIG and have an access to the core specification... I hou know another to do, I would appreciate !

So I can now have a better understanding on what happens in my case.
I also tried to simply associate (pair) my phone with the CC2640R2F, it appears as "bonded", but it still doesn't work.
In fact, I don't understand how I can find the right address to set in the wiltelist (the RPA).

I continue to read the documentation and will make test with another CC2640R2F and BTools.

To be continued !...
Best Regards.
PAtrick

HEllo

So here is my progress status :

- After pairing my phone :

      - the white list seemed to correctly manage connection,

      - I mean :

              - if phone is bonded, I can connect, disconnect, connect again... and Putty shows my true MAC address.

              - if not, I can connect only the first time, then, once I disconnect, the peripheral becomes no more visible (still advertising)...

      - I observe that the peripheral sometime disappears... without any reason,

      - So it's not so clean.

- Then I tried with another board running HostTest sample program and BTool :

      - At first, I tested BTools and HostTest program with ProjectZero program on the first board.

      - All was Ok and I become a little more familiar with the tool !

      - At next step, I followed the explaination of the Stack User Manuel (Using Privacy in BLE stack)

      - On the first board, I modifies and load SimplePeripheral program as explained.

      - But the problem I encounter is that I  cant set Btool because of an error with GapBondMgr_SetParameter : see picture...

      - I checkd twice, and I really followed all the explainations of the user manual

It's a long time I'm having this issue now, I think I will give up ad find another solution for my application.

Do you know if there is another way for having an efficient approach of this platform ?

I tried to find a training, but without any succes

Thank you for help again !
