On CYBT-483056 Eval I have created UART bridge which reads data from BlueTooth virtual COM port and transfer to PUART and other way round.

For reading I have use below task function. For 115200 baud rate I am misssing some of the byte chunks.

My initial guess is wiced sdk has some limitation on internal UART buffer which may get overwritten due to delay in reading or shorter buffer length. Not having access to wiced sdk I am not able to change the buffer size.

Please let me know if similar issue has been faced by anybody and any suggested fix will be appreciated.

#define MAX_BUFFER_SIZE 48
	static uint8_t readbyte[MAX_BUFFER_SIZE];
	static uint8_t toggle = 0;
	uint32_t recvcount = 0;

	while(1)
	{
		recvcount = wiced_hal_puart_rx_fifo_not_empty();

		if((recvcount > 0) && (recvcount < MAX_BUFFER_SIZE))
		{
			wiced_hal_puart_synchronous_read(&readbyte[0], recvcount);

			wiced_bt_spp_send_session_data(spp_handle, &readbyte[0], recvcount);
			WICED_BT_TRACE("%s handle:%d len:%d %c-%c, \n", __FUNCTION__, spp_handle, recvcount, readbyte[0], readbyte[recvcount - 1]);
		}

		wiced_rtos_delay_milliseconds(1, ALLOW_THREAD_TO_SLEEP);
	}

Hi @pghole ,

Can you check if you are getting this issue on Modustoolbox 3.0?  We no longer have support for wiced sdk.

Thanks and regards,

I am executing this on Modustoolbox 3.0. I think nomenclature used in shared library still use wiced_ as prefix for various library functions.

Hi @pghole ,

Yes, the APIs used in MTB do have wiced prefix. Since you mentioned wiced sdk, hence I asked if you are using wiced studios. Can you please give us more details about your application or share your project?

Thanks and regards,
