USB_Audio_Device_FreeRTOS sample project of CY8CKIT_062S2_43012 is targeted for AK4954 codec. How to modify the project for WM8960 codec if the mezzanine card is CY8CKIT-028-SENSE?

When sending data from PC via USB serial port to CYSPP CYBT-483039-EVAL, it appears to be over-running the CYBT, without CYBT ever asserting PUART_RTS low.

• CYSPP CYBT-483039-EVAL is connected to iOS app using EZ-Serial BLE CYSPP
  
• Data is being sent using the Acknowledged Characteristic  (101)
• PUART SW5 are all turned On
• After press reset switch on eval board, I see UART RTS pin Arduino J7-P6 go high on oscilloscope
  
• I set CYBT and flow control by sending following command to PUART from the PC.
  

• "STU,B=1C200,D=8,F=1,P=0,S=1\r\n"

When PC starts sending file data to PUART over USB serial, I see the data being received on the iOS side, however, some data is missing.

I expected  PUART RTS to be asserted low to prevent 3 MB of file data from over-running the CYBT, when sending data to PUART_RX ?

I do not see UART_RTS on pin Arduino J7-P6 being set low during the 3MB file transmission.

What are potential solutions to prevent data over-running when sending data to PUART RX for transmission to iOS device?

Thank you,

Hello,

I am using the EZ-Serial Host API Protocol Library with the CYBT-343026-01.

App: 1.2.29 build 29
Stack: 5.2.0 build 22
Protocol: 1.3
HW: CYBT-343026-01

I have a few modules that I re-flashed with EZ-Serial binary.
My procedure is to use ModusToolbox and flash the module with the Firmware_Upgrade_via_HCI application via the HCI UART. Then I use ClientControl to flash the module with the EZ-Serial Binary via the HCI UART.

The issue is, after I do this, all the modules have the same Bluetooth Device Address (MAC). I believe this is because the Firmware_Upgrade_via_HCI application has this line in the makefile.

BT_DEVICE_ADDRESS?=default

Per the documentation, this will set a BDA for your device by combining the 7 hex digit device ID with the last 5 hex digits of the host PC MAC address.

My question is, how do I prevent this. I want each module to have a unique MAC, preferably the MAC they had before I reflashed EZ-Serial.

Thank you,

We have a platform that uses WICED Version 3.7.0-7. AN STM32F469 processor uses the WiFi/BT module LBEE5KL1DX. We're able to bond with and connect and reconnect to a BTLE 4.0 keyboard without issues. When we do the same with the same model of keyboard that uses BTLE 5.0, we're able to bond with and connect with the  keyboard, but upon re connection, the firmware crashes. From the debugger, it seems to be crashing in a pee-compiled module we have: BTE_low_energy.FreeRTOS.LwIP.ARM_CM4.release.a.

Our belief is that something in the firmware is not handling BT 5.0 events correctly and is causing the firmware crash. But it isn't easy to tell what's going on in the project and the .a file is a bit of a mystery too. Are there any clues as to where to look for this issue? Is there perhaps an updated version of WICED or an updated driver file we should be using?

Hi,

I used two SPI's (SPI 1 and SPI 2) to communicate with two different flashes(Flash 1 and Flash 2) which are same IC make. I configured both SPIs identically. I may able to communicate with SPI 1 and Flash 1 but not with SPI 2 and Flash 2. I used four SPIs in my code. Is there any setting which i have to do to communicate with the SPI 2 and Flash 2?

So please help me to resolve this issue.

Thanks 

Is there any user manual or bring up sequence for murata 1XA bluetooth? I want use bluetooth on my specific evb but don't know how to enable it. etc. which driver? any patch? device tree? firmware?
