HI,

now i meet a problem with 4wire UART hardware flow control.

I config the baudrate with 115200 , 8/N/1 , NO hardware flow control and then try some hci command with such cmd , and get related command complete :

18:40:54.259 Packet "HCI_Read_Local_Version_Information", Opcode 0x1001

18:40:54.259 Parameters:

18:40:54.259 | Number HCI commands : 0x01

18:40:54.259 | Command Opcode : 0x1001

18:40:54.259 | Status : 0x00 (Success)

18:40:54.259 | HCI Version : 0x07

18:40:54.259 | HCI Revision : 0x0000

18:40:54.259 | LMP Version : 0x07

18:40:54.259 | Manufacturer Name : 0x000d (Texas Instruments Inc.)

18:40:54.259 | LMP Subversion : 0x9a1a

But if i setting the flow control with hardware, i can't get any response.

Thanks!

should i need the slow clock input as processors.wiki.ti.com/.../CC256x_Bluetooth_Hardware_Evaluation_Tool
?

i am using CC256xCOFN-EM and CC256xEM-STADAPT

Which host are you using? And which stack? I suggest taking FW logs, since it shows which HCI protocol detected etc too..

Thanks

hi , Hari.
I am using HCI Tester as the host to do some very simple testing.
How can i get the FW logs?

I check the CC256XEM-STADAPT, and find following description:

www.ti.com/.../swru417.pdf

The CC256XEM-STADAPT board serves as a translation board between a CC256xEM board (CC256XQFNEM, CC2564MODAEM, and CC2564MODNEM) and a STM32 MCU Evaluation board (STM3240G-EVAL and STM32F4DISCOVERY).

SO i can't use it with CC256XCQFN-EM ?

i try to use LA to find the problem, then i get the following waveform:

scenario 1: without hardware flow control.

i dont know why the RTS assert/dessert with TX.

scenario 2: with flow control.

i dont know why the RTS assert when receive 2nd byte(0x01)

hi Sir,
I finally find that problem was caused by the "Debug Header Component". When i remove it , that problem disappear.
