AIROC™ Wi-Fi and Wi-Fi Bluetooth Combos Forum Discussions

I'm tried porting exmaple(ble_hello_sensor, mfg_test).

but, all project some problem. When i using, maybe cy_rtos is  block or dead thread.

So, I can't passing bt_firmware_downlaod()

Can you Check my Codes?

Greetings,

I am trying to integrate LBEE5PK2AE-564 WiFi/BT module with USB interface (using CYW4373E chipset) with imx8mm (Android) and want to test WiFi/BT in Android, 

 i have tested the WiFi successfully and now trying to integrate and test Bluetooth, but in order to test the Bluetooth we used a binary (brcm_patchram_plus_usb_64bit) to load the firmware in the Linux but in Android the binary does not work as it is different linker.

For Example:

This is the binary you have provided:

# file brcm_patchram_plus_usb_64bit                                                                                

brcm_patchram_plus_usb_64bit: ELF shared object, 64-bit LSB arm64, dynamic (/lib/ld-linux-aarch64.so.1), BuildID=403983701e4aaf5728177f1e9b6e91db9354cdd1, not stripped

And this is present in our source for reference architecture:

# file cmd

cmd: ELF shared object, 64-bit LSB arm64, dynamic (/system/bin/linker64), for Android 30, BuildID=f97435a45132606a0c701ed5c1709bd5, stripped

And as you can see the dynamic lib linker is different. And when i execute the binary you have provided(given all permissions), I am getting the following error:

phyboard_polis:/vendor/bin # ./brcm_patchram_plus_usb_64bit

/system/bin/sh: ./brcm_patchram_plus_usb_64bit: No such file or directory

1|phyboard_polis:/vendor/bin #

1|phyboard_polis:/vendor/bin # ls -l brcm_patchram_plus_usb_64bit

-rwxr-xr-x 1 root shell 23840 2024-03-18 06:18 brcm_patchram_plus_usb_64bit

So I tried cross compiling by downloading the source code from GitHub but it throwing error. Please have a look at the error:

$ aarch64-linux-gnu-gcc -o brcm_patchram_plus_usb brcm_patchram_plus_usb.c -lbluetooth

brcm_patchram_plus_usb.c: In function ‘hci_send_cmd_func’:

brcm_patchram_plus_usb.c:311:9: warning: implicit declaration of function ‘writev’; did you mean ‘write’? [-Wimplicit-function-declaration]

 while (writev(sock, iv, ivn) < 0) {

        write

/usr/lib/gcc-cross/aarch64-linux-gnu/7/../../../../aarch64-linux-gnu/bin/ld: cannot find -lbluetooth

collect2: error: ld returned 1 exit status

And there is no libbluetooth.so in our toolchain.

 I request you to provide us with brcm_patchram_plus_usb_64bit binary which supports Android or please provide us with documentation or procedure to compile for Android or is there any another way to run the binary and flash the firmware.

 Thanks.

When i porting stm32h745 + Laird(lwb+), but stoped install firmware.

I think bluetooth sensor can't init hello_sensor_application_init(); 

But nucleo-745zi-q + Lwb(4343w) it's worked.

Hello,

We are using CYW43455 and its godzilla release on linux 5.15.71. Occasionally, when device comes back from deep sleep, CYW43455 shows its connected ( RSSI is being changed when getting closer or further to AP), IP address is there, but the network data doesn't come through. In addition it looks like that Rx counter showed in output of ifconfig command doesn't change when CYW43455 is in this state.

Can you please help solving this issue ? Is this a known issue, is there a patch for it ? Or we would need to come up with mechanism to detect this state and then try some recovery steps (reconnect, interface down/up, reassociate)?

Thanks,

Bogdan

Hello. What is the maximum data rate on an SDIO interface between an stm32h753vi and the CYW55573 (Murata Type 2EA)? 

Hello. I am wondering, to use the CYW55572 in the https://github.com/Infineon/AIROC-Wi-Fi-Bluetooth-STM32, which module should it be integrated in? Is the AW-XH327 module in https://www.azurewave.com/wireless-modules-infineon.html a good solution?
