Wi-Fi Combo Forum Discussions

Hi,

We are developing a WiFi, BLE, Bluetooth A2DP Capable Audio Player and Planning to choose Murata LBEE5PA1LD module for our requirement which contains Cypress CYW43438 and ST's STM32F412 Microcontroller.

One of the first major question I have related to CYW43438  since being a Broadcom Chipset, Does Cypress have a very closed/hard to reach documentation, development tools and development kits related to CYW43438  and WICED SDK which can be only accessed by paying a XXXX USD for license and then use it?

I do check the WICED Studio available online with WICED SDK, and it seems accessible easily. But I just wanted to make sure if there is any license requirement just like for the Broadcom or Qualcomm chipsets.

Is there any development kit based on CYW43438  and STM32F412 which can be used form application related to WiFi, Bluetooth A2DP Audio etc? I came across IMP Audio Kit https://developer.electricimp.com/hardware/resources/reference-designs/imp004maudiokit​ . But we are not planning to use IMP Library/API/Server and Not Sure if I will be able to erase default Code/Bootloader. But It should work. Is there any better option for development kit?

Regards,

Mahesh

Now I have a problem, do not know how to call the SDIO API interface.

What should I do if “platform“ is called and undefined

Here is my file:

I want to initialize the SDIO on the CYW943907AEVAL1F platform. What should I do,Thanks

Hi ,

We have using cypress wifi chip and integrated wifi driver and wifi HAL. Still WiFi bring up issue.

Dmesg log time: 

dhd_prot_ioctl : return error code-23 below error comes and i was check driver code and it check ifdef and return BCME_UNSUPPORTED rertun code by -23?

Cypress provide any patch overcome for this issue  -23 ?

logcat log with android HAL and wpa_supplicant:

--------------------------------------------------------------------

05-16 12:58:51.814  1048  1048 I wpa_supplicant: Successfully initialized wpa_supplicant

rfkill errror : rfkill unlock all required ? then below issue resolved?

05-16 12:58:51.979  1048  1048 I wpa_supplicant: rfkill: Cannot open RFKILL control device

05-16 12:58:52.030  1048  1048 I wpa_supplicant: rfkill: Cannot get wiphy information

After that wifi HAL error comes

05-16 12:58:52.086   128   128 E WifiHAL : Failed to register debug response; result = -23 --> Debug_command in WiFI Hal start request response failed ..libnl issue ? because call nl_sock_send_msg.  i have checking send_msg path ?

Hi ,

Could you please let me know if there is a way to read chip version on CYW43364 using only SDIO communication or SPI ( direct communication to the chip ) and not through WICED?

I just want to make sure the Soc is mounted at SMT process and read version is enough 

Hi Sir,

see comments below..How do you start  OpenOCD -WICED&CYW954907AEVAL1F....Jlink Segger?

OpenOCD -WICED

Downloading through Jlink Segger in WICED SDK 6.2 and future releases

Do any of the Wi-Fi eval kits for CYW 43907 or 54907 chips permit the user to conduct tests with an external amplifier and use the input from an external detector?

i have loading driver modules for my wifi AP6212(BRCM43430),when i ifconfig wlan0 up and start up the hostapd service i can find the hotpot, but when i running a application  of video in and out to lcd with mcu of hisi3519v101, the hotpot will disappeared immediately. also i try to start up the application firstly and then to run hostapd, the log shows that the ap enabled,but i can't find hotpot neither. do some guys have the same exprience(my kernel is 3.18, and the wifi driver backports form 4.14.77, using brcm/brcmfmac43430-sdio.bin for chip 0x00a9a6(43430) rev 0x000001, Firmware version = wl0: May  2 2019 02:39:18 version 7.45.98.83 (r714225 CY) FWID 01-e539531f)?

the log is:

first: i run hostapd and then run the application ,

~ # ifconfig wlan0 192.168.1.1

here i can find the hotpot. then i run the application, the hotpot will disappear.

second: i run application and then run the hostapd,
