CC2564MODA: set to normal mode to test mode through RF

Kaushik Chakraborty

Part Number: CC2564MODA

Hi,

I have two CC2564MODA, each of them connected with MSP-EXP432P401R. One of them i want to use as device under test (DUT) and another one as remote tester. I already flashed the DUT with HFPDemo_HF project, where i called VS_Enable_RF_SIG_Test_Mode(). I already verified, this way the DUT can turn to test mode (hopping to non-hopping) using a Bluetooth test equipment.

But, i am looking to achieve the same, using another CC2564MODA & MSP-EXP432P401R with HFPDemo_AG project, instead of utilizing  a Bluetooth test equipment like above.

I am looking for your guidance on this, to understand what are the API i need to use and in which sequence to achieve this utilizing HFPDemo_AG project. I had gone through http://processors.wiki.ti.com/index.php/CC256x_Production_Line_Testing_Guide, but it does not provide the information what i am looking for.

Thank you.

Best Regards.

    The CC256x IC cannot be a substitute for a Bluetooth test equipment. Unfortunately, what you are trying to do is not possible.

    hi Vihang,

    I am not looking for exactly behavior like a Bluetooth test equipment from CC256x silicon.

    I can do using HFPDemo_AG Inquiry, read remote name of HFPDemo_HF.  I am looking for the method of the following item.

    1. Connect to HFPDemo_HF using SCO

    2. Change Hopping signal to non Hopping signal

    thank you.

    best regards.

    This is possible using the default HFPDemo_HF.

    Bluetooth spec mandates minimum 20 channels as part of the protocol. So this is not possible when running a full use-case like HFP. You may be able to test a single frequency in PHY test mode (without the full use-case) when running with a PHY tester.

    hi Vihang,

    As i mentioned earlier, one of the board i flushed with HFPDemo_HF with calling VS_Enable_RF_SIG_Test_Mode() after initialization of stack.

    My objective to create a RF connection between the above board with another board with HFPDemo_AG. I used HFPDemo_AG default project and managed to create a link between both boards.

    After the connection get established, i can see RF signal in hopping mode through Spectrum Analyzer. Now, i am looking for a solution, using what i can stop hopping the signal and set it to a fixed channel.

    I am lacking of information about it. If you can share about the same, will be very helpful for me.

    Thank you

    Best regards

    By the way i am not looking forward any specific profile for this. So, not looking for full use-case of profile.

    the objective is to connect a classic device using another classic device (any profile does not matter, as i am not going to access the profile features), so can see the hopping signal. then change hopping to fixed channel through RF.

    Thank you

    Best regards

    When you are connecting the two applications like this, you are running the profile level use-case. It is not possible to limit the channel count to 1 (in other words, stop channel hopping) at this point. The problem is that You can get the board running the HFPDemo_AG to act as a DUT for BT testing. But you cannot make the HFPDemo_HF at the other end to act as a BT tester (e.g. stop channel hopping).

    There is no such profile for this scenario. You need a BT tester for this and a CC256x EVM will not substitute.

    I understand that, but fixed single channel operation is not possible for BT connection. It is different than the PHY level test case of single frequency.
