CC2564MODN: adaptivity test

Hi Fan,

Adaptivity is usually accomplished at an application layer - So you would create a BT connection and start sending BT data, and then the test house will run adaptivity testing. 

This code would need to be created by you.

Hi Vincent,

The test house said they need command to put the module into single frequency. So they could test adaptivity

We found in the below link, it has Packet RX/RX test command, HCI_VS_DRPb_Tester_Packet_TX_RX 0xFD85, 0x03, 0, 0xFF, 0, 2, 0, 27, 15, 1, 0x01FF.

So we sent it to test house. However, unfortunately, it still failed.

Would you please helping to check whether this is the right way to test adaptivity?

Thanks!

cheers

Hi Vincent,

Also I found a note in this command. We have not sent the commands of HCI_Write_AFH_Channel_Assessment_Mode 0x1 and HCI_Set_AFH_Host_Channel_Classification <ChannelMap>. Does it matter? Thanks!

Any update? Thanks!

Hi Fan,

I should have some feedback for you by tomorrow on this issue.

Hi Fan,

For BT, we certify at below 10dB which keeps us out of having to do adaptivity - So is this testing for BLE adaptivity?

Thanks,

Vince 

Hi Vincent,

If the E.I.R.P power from device is less than 10dB, the device does not need to pass the adaptivity.

But in our scenario, we have high gain antenna which exceeds the limit.

BTW, I checked the CE report for CC2564MODA. It has passed the adaptivity test.(page 24). Although we are using CC2564MODN, I think most of part should be the same as CC2564MODN. So I think TI must know how to test and pass the adaptivity. Thanks!7220.ER741325-04_R01_EN300328_Texas_CC2564MODA .pdf

Hi Fan,

It should be the test methodology described in the BLE Testing/Transmitter Testing here -https://processors.wiki.ti.com/index.php/CC256x_Testing_Guide#Transmitter_Test

Can you ask the test house what companion device they are using?

Hi Vince,

In the CE report of CC2564MODA, the adaptivity test is finished in BT Nom mode instead of BLE. The test house wants commands to lock channels for transmitand receive packed commands in normal link. So we gave test house the command, HCI_VS_DRPb_Tester_Packet_TX_RX 0xFD85, 0x03, 0, 0xFF, 0, 2, 0, 27, 15, 1, 0x01FF.. But it does not work for them.

Is there any special requirement about the companion device? The test house is using bluetooth speaker or mobile phone as companion devices, which they were using for testing other devices. It should not be a problem from their thoughts.

Thanks!

Hi Vince,

In the link below 

It says the command would be HCI_VS_DRPb_Tester_Packet_TX_RX 0xFD85, 0x03, 0, 0xFF, 0, 2, 0, 27, 15, 1, 0x01FF.

But 0x03 means device will work in single frequency. 

The HCI_Write_AFH_Channel_Assessment_Mode 0x1 and HCI_Set_AFH_Host_Channel_Classification <ChannelMap> only works for hopping frequency. Will they be related?

Should we use 0x00 instead of 0x30 to make device into hopping mode?

Thanks!

Yes, you should.
