CC2564C: CC2564C

Dan-E

Part Number: CC2564C

I am trying to put CC2564C chip in continuous transmit mode with no success. I followed the instructions described in the E2E page below.

e2e.ti.com/.../352985

It basically states following steps 1-4. I, however, need the command to be in VLCT format. I have successfully (I think!) translated the two last commands (3 & 4) but I am not sure about the first one (1). Could someone please check this and see if that is correct as I cannot get a continuous signal out from the chip...

/Thanks

1. download the SP.

2. Run hcitool cmd 0x03 0x001a 0x00

3. Run hcitool cmd 0x3f 0x01fb 0x01 0xff 0x00 0x00 0x00 0x00 0x01

4. Run hcitool cmd 0x3f 0x01ca 0x62 0x09 0x01 0x00 0x07 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00

What is VLCT format? Which Host are you using? HCI tester, Linux host?

Thanks

I am using a custom-made software which takes only takes VLCT commands. The "BTS transform" included in the "WirelessTools-4.0.0.2" has the capability of transforming from BTS-file to VLCT but the command below (hcitool cmd 0x03 0x001a 0x00) is a HCITool command format.

Did, you try selecting the 'custom Format' instead of 'HCI Format'?

I have now been able to set up the HCITester for this purpose. As mentioned I am trying to get a continuous Tx out of the chip but still no success.

I have done the below:

1- Reset the chip.

2- Download the SP

3- Run below commands using the HCITester

But the transmission is only a few seconds (1-10sec) and then it goes off again. Any ideas what is wrong?

After downloading the SP, please disable scans (page and inquiry) and then run the below commands:

HCI_VS_DRPb_Tester_Con_TX 0xFD84, 0x1, 0, 0, 15, 0x00000000, 0x00000000

HCI_VS_Write_Hardware_Register 0xFF01, 0x0019180c, 0x0101

HCI_VS_DRPb_Enable_RF_Calibration 0xFD80, 0xFF, 0xFFFFFFFF, 0x01

Thanks

Hi Again and thanks for your support.

I have been trying the commands you sent me many times with different variations (like Test mode on and many others...)

At one try I could get a continuous transmission (of close to 100!) but I could not repeat that even if I followed the exact procedure:

1- Restart (power cycle)

2- Reset

3- SP download (I use "initscripts-TIInit_6.12.26.bts". Is taht the correct one for CC2564C?)

4- Run the above commands

What am I doing wrong? Could you please double confirm if this is the whole thing or if a command is missing somehow?

https://e2e.ti.com/support/wireless-connectivity/wifi/f/968/t/352985?Continuous-TX-not-transmitting-continuously-wl18xx suggests a couple of more lines after NoScan. What commands are 3 & 4 in HCITester?

1. download the SP.

2. Run hcitool cmd 0x03 0x001a 0x00

3. Run hcitool cmd 0x3f 0x01fb 0x01 0xff 0x00 0x00 0x00 0x00 0x01

4. Run hcitool cmd 0x3f 0x01ca 0x62 0x09 0x01 0x00 0x07 0x00 0x00 0x00 0x00 0x00 0x00 0x00 0x00

I looped in our HW/Certification expert to provide additional suggestions/scripts.

Hi Hari/Dan,

The commands you are using appear correct. Typically when I run testing I am putting the device in test mode and using a CBT tester to perform BT performance measurements. Are you able to do the same?

Thanks,

Vince

Hi Vince,

I do not have the tester unfortunately. I am preparing the device for test at an external test-house as they have been unable to do the measurements on BT due to the fact that it refuses to send a continuous signal.

I have, as mentioned, tried almost everything. I see that the command "Send_HCI_Write_Scan_Enable 0x00" gives a result as if I change it to 0x03 it just sends around 1s while with 0x00 I get around 6-15s of Tx.

Is this a SP issue? I have used a few versions but have not seen any difference. Could you send me one you know that works and you have tested?

Also I tried disabling the sleeps using "Send_HCI_VS_Sleep_Mode_Configurations 0xFD0C, 0, 0, 0xFF, 0xFF, 0xFF, 0xFF, 0xFF, 100" and also "Send_HCI_Enable_Device_Under_Test_Mode" but no change in behavior.

Is there any other process that starts and could interrupt the Tx every 6-15s? Have tried a couple of other chips today, same issue.

/Appreciate all the help
