Wireless Connectivity Forum Discussions

Hi,

I am using a CYBT-343026 Bluetooth module connected to a MCU for wireless communication.

First step, the connection is Bluetooth serial port link only. The device can be found and paired. But we have a couple of questions to ask.

1. The friendly name is given by the MCU, most time the module does the advertisement with it no problem. However, I did see sometimes the friendly name is somehow seeing corrupted when a mobile scanned it. 

2. The module can be paired and connected. The connection seems not very stable and on mobile side, I can see it shows connection lost, and when tried to reconnect, it shows connection failed: read failed, socket might closed or timeout, read ret:-1

3. When connection is good, if I typed into the module from mobile side, it seems that the outgoing stream is affected, or even stopped. Is there any buffer issue there?

Thanks in advance for any help

Hello,

I am working on updating the EZ-Serial Module Firmware over OTA for the CYBT-343026 device. I'm using the image from CYBT-343026-01-EZ-Serial_v1.2.38.0.zip. I noticed that there are both .bin and .hex files available. While I was able to use the .bin file, I couldn't use the .hex file. Could you please explain the purpose of the .hex file?

Thank you in advance for your assistance.

Best regards,

Kazuki

Hi,

On the imx8mp solid run board, I'm attempting to activate the AP mode for Wi-Fi settings.

And to enable AP mode, I followed the instructions listed below. But I'm struggling a little.

Steps Followed:

modprobe moal mod_para=nxp/wifi_mod_para.conf

vi /etc/hostapd.conf

     interface=mlan0
     ssid=test
     hw_mode=g
     channel=1
     ieee80211n=1

iwlist wlan0 freq

killall wpa_supplicant

killall hostapd

ifconfig wlan0 192.168.1.10 netmask 255.255.255.0 up

route add default gw 192.168.1.1

hostapd /etc/hostapd.conf

Log:

root@imx8mpsolidrun:~# hostapd /etc/hostapd.conf

wlan0: interface state DISABLED->DISABLED
wlan0: interface state DISABLED->DISABLED
wlan0: AP-DISABLED
wlan0: CTRL-EVENT-TERMINATING
hostapd_free_hapd_data: Interface wlan0 wasn't started

Please let me know if the process i have followed is correct.

We are using the EZ-serial firmware V1.2.36 of the CYBT-343026-01 module. After power on of the module I use an android device to connect to the BLE peripheral interface for Unacknowledged data. Connection succeeds, but serial data is not forwarded to the BLE connection unless ~50 seconds has passed or a full 20 characters are sent. The packetization mode is Anticipate (1) with default parameters (5 ms, 20 characters). What could be causing this 50 second delay? Its almost as if the 5 ms timer is not expiring.

I can send data on the BLE connection and it is transmitted on the serial interface immediately.

After waiting the 50 seconds after power on then serial data is transferred over BLE without delay.

If I change the packetization mode to Immediate (0) then the serial data is passed to the BLE connection with no delay.

Hi Team,

We have used CYW43439 in our design,  can you share how we can integrate in Linux kernel version 6.1

Also if you can share the NVRAM bin file, Firmware file and CFG file for LINUX Kernel version 6.1. this will really help

Hello Infineon support team.

We would like to refer to a schematic of CYW920721M2EVB-03.

Could you provide the schematic?

Thanks,

Hi, 

I need latest  WL Tool Supported with all country codes + ETSI standard.

Kindly provide the wl tool source & Build procedure document + MFG Firmware Build procedure Document.

How to build WL Tool + MFG Firmware in Yocto?

Thanks & Regards,

Hi.

I am currently using Laird LWB+ CYW43439 with WHD successfully in AP and STA modes.

But now I would like to use it in WiFi Direct/P2P mode.

Is it possible to use Laird LWB+ CYW43439 and WHD for WiFi Direct/P2P mode? If so, what would I need? are there any examples?

Thanks in advance.

Using Fedora38 on two systems with BCM4356 802.11ac Wireless Network Adapter I get these messages and WiFi results:

Dell Inspiron 660

2.4GHz and 5GHz are not working

For both cases I have tried with several available firmware files that we can get from linux-firmware and although I get rid of the log error, nothing changes.

For the imx board, we need a configuration file to get the 2.4GHz band working and get a correct association although 5GHz band is still not working. The configuration file that I have tested is a generic one (https://chromium.googlesource.com/chromiumos/third_party/linux-firmware/+/f151f016b4fe656399f199e28cabf8d658bcb52b/brcm/brcmfmac4356-pcie.txt).
While, for the commented intel platform, the configuration file is not necessary to get the 2.4GHz band working and get a correct association but 5GHz band is not working with everyone I have tried.
I have read that this configuration file is related to some nvram configuration values but nothing else.

We would need to be able to use the 5GHz band for both cases.

I have asked to NXP, Intel and Broadcom and everyone redirects me to Infineon in order to solve these issues with this card.
Could yu help me? Could you clarify which firmware and configuration files are necessary?

Thanks
