CC2564MODN: BLE power change option

ABHIJITH PR

Part Number: CC2564MODN

Is there any commands available to change the power level of CC2564MODN module in its BLE mode of operation ?. In operating manuals it is given as fixed power, but for the compliance certification testing of the product the BLE power changing option is needed. Please help on this asap.

Did you take a look at the wiki:

yes, actually we have followed the same document for the code scripting. But the BLE power adjustment option is not working. it remains constant at 12 dBm

Hi,

For the documentation you need to change the power level vector 1 in the table. This is what is used for BLE power. Note that when you do the command, it is listed from 0 to 15, not 15 to 0, so ensure that you are properly changing the correct value in the command. In this way you should be able to change the BLE power.

Note that for this to take effect you need to load the .bts file, then follow the example script to do this. IF you load the default an run the radio, you need to reset the radio or the command will not take. So the procedure should be to load the .bts file, then load the commands for changing the power vector, then run the BLE modulation.

Thanks,

Riz

we tried that options and now we are able to change the power. But the signal looks unusual as the following shows. it doesn't looks like the BT signal. Below are the commands which we have used for the same

hcitool cmd 0x3f 0x15b 0x01 0x01

hcitool cmd 0x3f 0x177 0x01 0x00 0x0000 0x71764129 0x00 0x00 0x00 0x00 0x00 0x00000000

hcitool cmd 0x08 0x01e 0x00 0x30 0x04
