- How should I use the CYW43438WCD1 bluetooth module?
- Do I need another MCU to run the BT stack like blueZ?
- Can the MCU of the EVB supports both WIFI and BT?
- Tks!
One of our customers is trying to get KCC certification.
KCC requires less than -54dBm integrated power at 1MHz RBW.
Our module, based on CYP43362, is failing by about 5-8 dBm.
Is there any way to tweak LO power or feedthrough using NVRAM parameters?
thanks
Show LessWhen setting up a USB Storage Device, do I have to use FATFS or can FileX be used? FileX supports FAT32 & exFAT so it should work, right?
Also, I cannot find a USB Storage Device example anywhere, any pointers?
I found this Configuring CYW943907AEVAL1F as USB device but it has a scary ending: "Note: The USB Device functionality does not work for device classes (For instance, mass storage class) that use a transfer data length which is a multiple of the maximum packet size. Currently there is no workaround for this issue. The issue is being investigated and will be updated once there is a solution or workaround identified"
Show LessHello,
We are using BCM4390X controller(used part: ISM43907-L170) in one of our project.
we have connected li-ion gauge IC(part no: LC709203F) to BCM4390X controller through I2C interface.
we are facing probe failure, read/write failure in both I2c standard mode(100khz) and high speed mode(400 khz).
When we are trying in i2c low speed mode(10Khz) only, wiced_i2c_probe is getting succeed
we are trying to read/write I2C based li-ion gauge IC(part no: LC709203F), li-ion gauge IC always reads default as 0xFF only on I2C low speed mode.
Show LessHi,
The WICED-Studio-6.0.1 uses an old version of mbedTLS library (v2.4.0).
I'm wondering if WICED is impacted by below vulnerability?
https://tls.mbed.org/tech-updates/security-advisories/mbedtls-security-advisory-2017-01
https://tls.mbed.org/tech-updates/security-advisories/mbedtls-security-advisory-2017-02
https://tls.mbed.org/tech-updates/security-advisories/mbedtls-security-advisory-2018-01
If yes, please include the fix in the upcoming release.
Thanks.
Show LessHi, nvidia jetson tx2 module is with CYW4354 (BCM4354).
We would like to know is there any tool or driver (through cmd) to set up/configure channel/power level/data rate/band, etc..
Show LessWe are working on CYW43907 Platform application development.
Evaluating the powersave mode, monitoring the Current prover.
CYW43907 shows the different Beacon reception time.
sometime, it takes around 10msec. but other time , it takes around 1-2msec (short time !!!)
<PS1> allways 10msec
<PS2> allways 1-2msec
<PS3> conbination of 10msec and 1-2msec
Is there any reason why?
We need to know why it behave like this.
In order to save battery power, of course we prefer to have 1-2msec reception time.
Is ther anyway to get shorter Beacon recpton time.
We are quite uergenty clarify this issue , your quick advise.comment will be very apreciated.
BRDs.,
Keith
Show LessI was looking through the forum for an example of how the CYW943907 eval board, when configured as an HTML server, could process fields from a form using "post". I was able to follow the "application" example in the SDK which uses "get". Any pointers on this one? Thanks!
Show LessDear Sir,
Could you help me to check this error when connection websocket using Websocket Server Example on WICED 6.1.2
I just test some application on Windows Client Socket, and the application is okay, it can connect in both ws and wss(tls 1.1).
But when i write it on android application, it can just connect to ws, the feature wss (tls 1.2) can not work. (The android application i try on echo.websocket.org still okay in both mode ws and wss)
The Debug Log i got on WICED device:

Please check it for me what i do wrong.
Thank you
Show LessSTM32F411 has 128KB RAM and 512KB serial Flash, and we added EXT.2MB on the module.
We will download application from serial Flash to RAM when boot.
I think that the part data in serial Flash downloaded to RAM, is it right?
If right, could you tell me that what part of the data will be downloaded?
If the downloaded size is larger than RAM(128KB), how can we solve this problem?
Thanks
Y.Jiang
