BLE Test Mode

It is possible to put the CC2540 into direct test mode by using the following HCI functions:

HCI_LE_ReceiverTestCmd

HCI_LE_TransmitterTestCmd

HCI_LE_TestEndCmd

These functions implement the BLE direct test mode commands defined in the BT 4.0 spec. The function prototypes can be found in hci.h.

We need to know how to use the HCI_LE_TransmitterTestCmd() functions.

I’m writing the BLE direct test mode project based on the HOstTestRelease-CC2540EM Master project.

I’m adding code below in the end of HCI_EXT_App_Init() function:

HCI_LE_TransmitterTestCmd(0,HCI_DIRECT_TEST_MAX_PAYLOAD_LEN,HCI_DIRECT_TEST_PAYLOAD_PRBS9);

Will this simple added line work for the transmit Direct Test Mode test? Thanks!

BLE CC2540 Output Spectrum

Hi Willis,

My name is Kyle Lee from Samsung Electronics,

I am working on Bluetooth LE Direct  Test Mode now and got a problem for Receiver test.

We are actually using a lot of BT chipsets and one of these is TI, but actually we are using BlueZ stack.

So I would like to ask about Receiver test on BlueZ level if you are possible.

I saw your comments about LE test mode via Googling. I think you are an expert on this.

The problem is that we don't know how to get the PER and the Packet counts against  'LE Receiver Test'.

Actually I can verify that this cmd has sent to the chipset but I don't know the result.

so if you know how to parse the result against LE receiver test, please give me some hints.

It will be very helpful,

My email is kyonghun.lee@samsung.com

Please help me~

BR,

Kyle Lee

I implemented:

HCI_LE_ReceiverTestCmd

HCI_LE_TransmitterTestCmd

HCI_LE_TestEndCmd

I don't know how to get the packet report after issuing HCI_LE_ReceiverTestCmd followed by HCI_LE_TestEndCmd. HCI_LE_TransmitterTestCmd works fine.

Does this help?

Hi Leo,

Is this the same information returned from HCI_EXT_PER?  (11.21 HCI Extension Packet Error Rate)

Is there a GUI tool to send the direct test mode commands.   I see commands in BTool but they are not the same.   I have seen the commands in an extension of the HCI Test tool but that tool seems to have limited com port capability (goes up to com6 and I'm at com30)

I'm using the CC2540 USB Dongle from the CC2541DK-MINI kit and need to do the Core 4.0 RF tests.

I was able to figure this out.    The com port does show up in HCI Test.  I had made a mistake on the setup.

And the HCI test does have the library for HCI LE specific commands.

My question now is why are these not in BTool?
