HCI UART on CYBT-343026

[wenchilo]

Hi, I am working on CYBT-343026 with SPP and HCI UART.  I have view following question and run the attachment file.

https://community.infineon.com/t5/Knowledge-Base-Articles/How-to-Use-HCI-Raw-Data-Mode-in-CYW20706-K...

And my RX did work but my TX didn't work while I call wiced_transport_send_data(). I want to know what might be the problem.

Thanks

Hi,

May I know which software/IDE are you using?

Have you configured the PUART pins correctly?

The KBA is written for CYW920706WCDEVAL kit in WICED SDK. When I checked the platform files in the latest software the pins are as below for PUART. Please check whether you have done any mistake related to the puart pins.

CYW920706WCDEVAL 

#define WICED_PUART_TXD WICED_P31 /* pin for PUART TXD */
#define WICED_PUART_RXD WICED_P33 /* pin for PUART RXD */

CYBT-343026-EVAL

#define WICED_PUART_TXD WICED_P31 /* ARM GPIO pin for PUART TXD */
#define WICED_PUART_RXD WICED_P04 /* ARM GPIO pin for PUART RXD */

Thanks,
