Original question:

CC2560 hopping sequence for Japan

CC2560: CC2560 hopping sequence for Japan

user5163378

Part Number: CC2560


Hi specialists,

it seems that classical BlueTooth certífication for Japan still makes trouble like in the year old thread below.

We habe an CE and FCC certified application based on the CC2560 and it turns out that the 17 testmodes described in the TI processor Wiki are not sufficient at all.

They are:; 

BT Test Cases

Below are the test configuration modes for Classic BT:

  • TM1: TX MODE GFSK CH 0(2402 MHz) 3Mbit
  • TM2: TX MODE GFSK CH 59(2441 MHz) 3Mbit
  • TM3: TX MODE GFSK CH 39(2480 MHz) 3Mbit
  • TM4: TX MODE 8DPSK CH 0(2402 MHz) 3Mbit
  • TM5: TX MODE 8DPSK CH 59(2441 MHz) 3Mbit
  • TM6: TX MODE 8DPSK CH 39(2480 MHz) 3Mbit
  • TM7: π/4-DQPSK modulation CH 0(2402 MHz)
  • TM8: π/4-DQPSK modulation CH 59(2441 MHz)
  • TM9: π/4-DQPSK modulation CH 39(2480 MHz)
  • TM10: AFH (Adaptive Frequency Hopping) mode
  • TM11: Hopping on all channels with data packet mode DH1
  • TM12: Hopping on all channels with data packet mode DH3
  • TM13: Hopping on all channels with data packet mode DH5
  • TM14: TX MODE no modulation (CW) CH 59 (2441 MHz)
  • TM15: RX MODE CH 0 (2402 MHz)
  • TM16: RX MODE CH 59 (2441 MHz)
  • TM17: RX MODE CH 39 (2480 MHz)

The teslab requires 6 more modes and describe them:

1. Hopping On channels with data packet mode DH5 20channel.

2. Hopping On channels with data packet mode 3DH5 79 channel.

3. Hopping On channels with data packet mode 3DH5 20 channel.

4. Hopping On channels with data packet mode DH5 79channel.

** For #4, pls apply modulation with the hopping stopped.

5. Hopping On channels with data packet mode 3DH5 79 channel.

** For #5, pls apply modulation with the hopping stopped.

6. Hopping On channels with data packet mode DH5 79channel.

** For #6, this should be receiving only with transmission stopped.

Is there anyone of you who know what exactly is needed?

Thanks in advance,

Matthias

    Hello Matthias,

    we have many customers using the CC256X family in Japan with no issue.
    can you please share the exact .bts file you are using so we can better understand what is your issue.

    Dear Chen, 

    thank you for the reply. There is no special file i could send.

    The question is, what are the desired testmodes for classical BT in japan beside

    the 17 testmodes found in the processor wiki for the 2560 device as listet below.

    Hello Matthias,

    Concerning the file it's weird you can't share it - without such a file you are running the ROM Version.

    I'm looping in Riz that can help you with Japan certification.

    Hi Chen,

    it's not weird having no file to share as i only lead the communication between the testing house and the software engineers.
    We are able to fire up the HCI tester commands as below TM1-TM17 like  described in the processors wiki.

    The question is: who has the knowledge  which more test modes beside TM1-17 are needed for japan certification and not how to code them.

    A answer could be: hop to channel 36, apply modulation for 2 seconds ... hop to channel 75 ... The question is the procedure not coding it.

    Hello Matthias,

    I understand that.
    I'm currently checking the exact details you need and will provide them asap.

    Concerning the file - what i didn't understand and now i can understand more is how come you don't have it - i thought you had a system and was running tests internally.

    Now i understand you don't have the board in front of you - therefore don't necessarily have access to all needed files.

    I'm looping in our certification expert and he can help with your questions.

    BR,

    Hi Matthias,

    I hope all is well. A few comments here:

    1) Please provide the wiki page that you are referring to with the TM1-17 commands for review

    2) For Japan certification I am not aware of are requirement to go into the test modes that you are referring to. We have done Japan certification on our Wilink devices that basically contains the CC2560 device integrated with Wifi. The requirements you are referring too are not part of Japan standard for certification. They will look at each modulation to ensure it meets the requirement, but no test modes as you are stating.

    3) With the Use of the following HCI command (HCI_VS_DRPb_Tester_Packet_TX_RX (0xFD85)) you can set up the packet lenth and modulations you require., however you cannot select the number of channels to hop on. You can refer to the wiki here: http://processors.wiki.ti.com/index.php/CC256x_VS_HCI_Commands#HCI_VS_DRPb_Tester_Packet_TX_RX_.280xFD85.29

    Thanks,

    Hi Riz,

    thank you for your good input.
    This is where we have the basic knowledge from:

    processors.wiki.ti.com/.../CC256x_FCC_Certification_Guide

    and this 17 Testmodes we implemented.
    Today i got this from the testing house:

    ** The objective of #4 and #5 is to measure the burst ratio for the DH5 packet and 3DH5 packet. As such, all other operations in the DH5 packet and 3DH5 packet should be the same with hopping stopped on channel 2441MHz. From the testing organization's understanding, the modulation for DH5 packet is GFSK (1Mbps), and the modulation for 3DH5 packet is 8DPSK (3Mbps). Are these correct?

    ** The objective of #6 is to measure the noise for the DH5 packet and 3DH5 packet when receiving a signal. Pls turn off only signal transmission for the DH5 packet and 3DH5 packet. All other operations for the DH5 packet and 3DH5 packet should be controllable. They expect to be able to use any channel at random channel from the 79 channels. If there is a difference in the reception between the DH5 packet and the 3DH5 packet, pls make a reception mode for the 3DH5 packet as well.

    This is additional to the Wiki modes.

    Hi Matthias,

    Thank you for the link. I am aware of this one, but was looking for if you got the script commands from the wiki. I guess this was implemented on your side then.

    As for the additional test cases the HCI command I provided would be what to use. Within there you can select hopping or a fixed frequency. In this way you can run hopping, take the measurements you need then run in fixed mode and repeat the measurements and get the ratio that you are looking for.

    For the DH5 and 3DH5 this is correct as stated above.

    Again for Japan, and reviewing our reports for what we have previously done I don't see the requirement you are listing...

    Thanks,
    Riz
