Hi Community,

We are testing Bluetooth Radio Receive on Infineon chip CYW54591 by the steps provided from the below document:

https://www.infineon.com/dgdl/Infineon-ModusToolbox_WICED_Manufacturing_Bluetooth_Test_Tool-Software-v01_00-EN.pdf?fileId=8ac78c8c7e7124d1017e9149d76c1593

1. Installed ModusToolbox

2. Created an empty application project (haven't downloaded to the device).

3. Ran the wmbt tool from: "C:\Users\<username>\mtw\mtb_shared\wiced_btsdk\tools\btsdk-utils\<branch>\wmbt".

4. Below are the commands we used to test  Bluetooth Radio Receive. But we couldn't get any statistics report as the document claimed "The WMBT reports connectionless Rx Test statistics every second."

May I know how to get the Rx Test statistics report? Thank you

Reference design for BGT24ATR11, currently ready to use this chip for radar level meter.

smartconx_target@Q!w2e3r4t5y6u7i8o9p0||/t5/AIROC-%E8%93%9D%E7%89%99/BGT24ATR11-%E7%9B%B8%E5%85%B3%E7%9A%84%E5%8F%82%E8%80%83%E8%AE%BE%E8%AE%A1-%E7%9B%AE%E5%89%8D%E5%87%86%E5%A4%87%E4%BD%BF%E7%94%A8%E6%AD%A4%E6%AC%BE%E8%8A%AF%E7%89%87%E5%81%9A%E9%9B%B7%E8%BE%BE%E6%B6%B2%E4%BD%8D%E8%AE%A1/td-p/740735

My setup:

- ARM host processor running 5.15.67 Linux. 

- Murata 1MW BT/Wi-Fi combo chip (BCM43455) over SDIO using OOB wakeup

- Wi-Fi firmware: version 7.45.265

- Using linux/hostapd patch sets from "cypress-fmac-v5.15.58-2023_0901"

Problem Summary:

My issue is that when I enable Wi-Fi on my board, Bluetooth audio performance becomes extremely poor - full of cracks and pops.

Extensive testing has shown that this issue occurs after a specific sequence of events:

1. Power on the board
2. modprobe brcmfmac
3. Start Bluetooth stack, connect to a headset device using HSP and establish SCO connection
4. Now, start wpa_supplicant and scan/connect to a 2.4 GHz AP - Audio distortion begins during scan.

Additional details:

I have already enabled some coexistence parameters in the NVRAM file:

btc_mode=1
btc_params8=0x4e20
btc_params1=0x7530
btc_params50=0x972c

The problem occurs with or without these parameters.

Also, I notice that if I remove the brcmfmac module and re-insert it between steps 3 and 4 above, the problem seems to go away, or at least become much less likely. 

Possibly related issue:

My suspicion is that the 43455 is entering a state like it was in my other post from a couple years ago

Removing brcmfmac module impacts Bluetooth audio... 

I have not tested to see if the above issue still exists. I have been avoiding module removal as a workaround. 

Would Infineon be willing to investigate this issue?

Hi

I want to us HID at cyw20706.

https://community.infineon.com/t5/ModusToolbox/I-can-t-find-HID-example-in-ModusTool-box/m-p/399265#M2521

Based on the above question, an example exists for cyw20835.

I wonder if this example can be applied to cyw20706.

I was told at the time that it was not possible, is it the same now?


Thank you.

Regards,

DevRyan.

When i reboot mcu with cyw43439(Laird sterling lwb-plus), my ble chips not working.

but my mcu system reset 5~10 times it work okay.

In this specific situation, wpa_supplicant (wpa_cli) is used when the device which has CYW43455 1MW  chip is in normal mode. When the device goes to deep sleep( linux  goes suspend to RAM mode) 1MW chip goes to power-save mode.

My question is when the device is in the state above, can we use internal supplicant  to offload gtk rekeying ? And is it possible that when the device is back to normal state to external and internal supplicant are used simultaneously?

Hi-

I just finished install Eclipse IDE for Modustoolbox and followed 

chrome-extension://efaidnbmnnnibpcajpcglclefindmkaj/https://www.infineon.com/dgdl/Infineon-AN238254-Getting_started_with_AIROC_CYW20829_Bluetooth_LE_on_ModusToolbox-ApplicationNotes-v02_00-EN.pdf?fileId=8ac78c8c8929aa4d018a3fe0cbc05aba

to create new BLE application.

Here is the error from "New Application" shown in Choose Board Support Package - Project Creator 2.20 Window.

Hi

We recently started to play with the CYW20829 chip and are considering migrating a hardware application we originally built on the CYW20719B2 chip to it.

In porting code for a SPI NAND Memory chip over to the new 20829, we are having trouble mapping the WICED APIS to the CY_HAL API's and getting them to work.

We are not getting any errors from init, are using the default PINS on device configurator for the 20829, but we are getting fails on reading and writing using  cy_hal_spi_slave_read, and cy_hal_spi_slave_write. 

Here is a snippet from the 20719B2 Code that sets up the device and our attempt to migrate the equivalent code to 20829

Our code drives the CS pin High and Low before doing Read/Writes w/o issue on the 20719, but not sure we have the correct method figured out on the 20829

20719 INIT Code

wiced_hal_gpio_select_function(NAND_CS_PIN, WICED_GPIO);
wiced_hal_gpio_select_function(NAND_SCK_PIN, WICED_SPI_1_CLK);
wiced_hal_gpio_select_function(NAND_MOSI_PIN, WICED_SPI_1_MOSI);
wiced_hal_gpio_select_function(NAND_MISO_PIN, WICED_SPI_1_MISO);
wiced_hal_gpio_configure_pin(NAND_CS_PIN, GPIO_OUTPUT_ENABLE | GPIO_PULL_UP, GPIO_PIN_OUTPUT_HIGH);

wiced_hal_pspi_init(SPI1,FS_NAND_HW_SPI_CLK_FREQ / 2,SPI_MSB_FIRST,SPI_SS_ACTIVE_LOW,SPI_MODE_3);

20829 INIT Code

20719 Drive CS Up or Down

wiced_hal_gpio_set_pin_output(NAND_CS_PIN, GPIO_PIN_OUTPUT_LOW);

wiced_hal_gpio_set_pin_output(NAND_CS_PIN, GPIO_PIN_OUTPUT_HIGH);

20829 Drive CS Up or Down

We have tried both of these:
cyhal_gpio_toggle(CYBSP_SPI_CS);

or

cyhal_spi_slave_select_config(&mSPI,CYBSP_SPI_CS,CYHAL_SPI_SSEL_ACTIVE_LOW);

cyhal_spi_slave_select_config(&mSPI,CYBSP_SPI_CS,CYHAL_SPI_SSEL_ACTIVE_HIGH);

Our Read/Write Looks like this

20719

wiced_hal_pspi_rx_data(SPI1, NumBytes, pData);

wiced_hal_pspi_tx_data(SPI1, NumBytes, pData);

20829

cyhal_spi_slave_read(&mSPI,pData,&size,10);

cyhal_spi_slave_write(&mSPI,pData,&size,10);

Any help would be appreciated !!
