Hi,

Please open a support case and request a beta release. I am uncertain if the request can be honored but you can ask. www.nordicsemi.com/.../Contact-Support-Team

Hi,

Ok Thx! But can we do something manually to the setup without waiting the update? If not, do you know approximatively when this issues will be fix because i'm little short in time?

And if i created a support case in the nordicsemi website, do you think the fix will comme earlier?

Hi,

I think the nRFgo studio is supposed to automatically fix or partially fix the PAN #4 while generating the Setup. However I think an nRFgo studio issue may have created this issue for you. I will request an update of the nRFgo studio to fix this issue.

Hi,

Thx for the fast reply! =)

Your files works good on Android! So i must success to connect our devices, but i can't find what's wrong in our setup. I think that we avoid all the workaround from the PAN #4, but there is perhaps a misunderstanding from one of those.

If you have time, can you check our setup? Perhaps you will directly find what's wrong

Hi,

I think the issues that you are seeing are related to the C version PAN #4. I have attached a services.h file and a ublue_setup_gen.out.txt that should work for the Android 4.3 and the C version of nRF8001.

You may need to reset your phone before testing it to remove any cached GATT handles.

Let me know how it goes.

I've done two tests on a C revision: One with a bluegiga dongle and one on a Samsung S4 with Android 4.3. Here is the result from the bluetooth chip using UTF-8 Tera Term Pro:

    Dongle:
        Ready
        Bonding...
        Connected: I00120, L0000, T01000, A050
        Bond OK
        Pipes open: 00, 02, 03, closed:
        Pipes open: 00, 02, 03, 04 closed:
        Pipes open: 00, 01, 02, 03, 04 closed:
        Data:?
        +000.000
        DC:+1
   

     Android:
        Ready
        Bonding...
        Connected: I00048, L0000, T07000, A100
        Bond OK
        Pipes open: 00, 02, 03, closed:
        Disconnected: Remote user terminated

As we can see, the process is exactly the same for the two methods. Just for Android, I terminate the process after ten times trying to discover services but nothing happened during these. Perhaps C revision can't be connected on an Android phone.

If someone has successfully connected a C revision to an Android phone using the build-in API, can this person send me the corresponding piece of code or just explain me how he manages the connection and the services discovery.

I'm using a Samsung Galaxy S4 with Android 4.3 and a Nexus 5 with Android 4.4.2. These two are relatively stable when I use them to communicate with a revision D. At first, i've worked with a Nexus 7 with Android 4.3 and with this device I had pairing issues (can't unpair, pairing request doesn't show), unstable bluetooth (randomly disconnecting) and a lot of headache ^^

Hi,

When using a C version of the nRF8001 you should use the Setup format for the C Revision, when the D version of the nRF8001 supports both the Setup Format for D and C revision. So any code created for C should work on D. However any code for C may not work on D and must be explicitly tested. The Setup Format is selected in the nRFgo studio -> nRF8001 Configuration -> Device in the top of the configuration page.

The Product Anomalies that exist for the C revision are fixed in the D revision. See the list of anomalies here

The Product change notification between the C version and the D version is here.

You should check the status code of the Command Response Events that you are receiving from the nRF8001, this will give you required guidance to fix the issues.

Which Android device are you using? Some devices has pairing issues when running Android 4.3.
