Ping with data of size 1500 fails. We are able to send TCP packets with fragmentation but ICMP fails. Is there anything specific we need to do to get ping to work?
Show LessCEL provides a broad range of wireless solutions, including its Cortet™ Modules, SiPs, IP Bridges, Embedded Software, Apps, and Device Cloud offerings. CEL allows its customers to 'Connect with Simplicity', circumventing the complexity of IoT connectivity by providing full turnkey solutions - many of which are based on Wi-Fi and Bluetooth technologies. Our 60 year heritage in wireless coupled with our sales of 3M+ modules to date are testaments to our commitment to quality and our ability to scale for this prolific segment of the wireless market.
Our Cortet™ WB4343 Wi-Fi + BLE module allows you to bypass the headaches associated with RF design, RF test and FCC/IC/CE certifications. Simply drop in the fully integrated device for complete turnkey solution.
CEL's WB4343 Wi-Fi + BLE SiP offering utilizes the same chipset as used in its module sibling. Migrating to a SiP-based design is quick and easy since you can simply port over the same embedded code as used on the module. SiPs come fully RF tested and pre-certified to work with common antenna elements.
Both WB4343 module offerings support the WICED SDK.

Show LessI am using the STMF411, I have 512KB. How would I go about minimizing the DCT image and moving the start location of the app lower in memory?
We are using the host in production so it's imperative we fit everything in the ST's flash because it reduces boot time significantly. We can't afford to wait approximately 5 seconds for each module to wait for the wl task to init.
Thanks for your response!

Show LessHi All,
For production reason, using openocd with sflash_write.tcl to program external flash is slow. (67KiB /s)
We tried enabling MCU PLL clock and increasing adapter_khz to 8000 and achieved 140KiB/s.
(more adapter_khz doesn't help)
Is there any other parameter can be tuned for faster SPI flash programming ?
ps. we are working on STM32 platform. but similar issue also apply to 439x platform.
Show LessI want to obtain network address information. Linux has its own getAddrInfo() method. I am not sure if netdb.h is in the compilation path for WICED SDK. is there an alternative?
Show LessI am using WICED SDK 3.5.2 and was trying out the shadow demo app. However when I provide the certificate and the private key for AWS IOT from the browser (device_settings.html), the browser never completes the second upload. I have tried uploading the certificate and the key in different order and I always face issues with the upload of the second file.
I am using dev kit BCM943362WCD8.
On further investigation I discovered that the browser doesn't get a response back for the second chunk of the second file. I looked at the demo code and upon some debugging I have narrowed down the problem to writing the security section to DCT. The code never returns from that call. Therefore the response code which is immediately after the DCT write code never gets executed and the browser never gets a response.
Has anyone faced the above issue? How did you solve it?
I have tried erasing the flash (see flash erase result below) with no success in running the shadow app.
> sam4s_flash erase_sector 0 2 5
sam4 does not auto-erase while programming (Erasing relevant sectors)
sam4 First: 0x00000002 Last: 0x00000005
Erasing sector: 0x00000002
Erasing sector: 0x00000003
Erasing sector: 0x00000004
Erasing sector: 0x00000005
erased sectors 2 through 5 on flash bank 0 in 0.214057s
Thanks

Show LessHi,
I'm trying to enlarging the SRAM usage of my application by replacing STM32F417 to STM32F437.
Is there any modification required for utilizing the full SRAM space (256 kbytes) of STM32F437? Except modification on the file 'platforms/BCM943341WCD1/BCM943341WCD1.mk'?
HOST_MCU_VARIANT := STM32F437
HOST_MCU_PART_NUMBER := STM32F437IGH6
From the platform linker configuration /platform/MCU/STM32F4xx/GCC/*, I don't see the difference between STM32F417 and STM32F437.
Show LessIt would be great if I could stop anyone with a JTAG device from reading the firmware off my BCM943362WCD4.
How do I protect my firmware from being read off the device?
Show LessHi,
As WICED platform released along with BESL (uSSL package from cypherbridge, I would like to know if BESL utilize the hardware crypto ability (if available) provided from STM32 series chip?
I found remarkable performance dropping while doing 'wiced_tcp_start_tls', it costs around 1.5s to complete its initialization.
And any options for replacing BESL with other SSL/TLS solutions?
Show LessHi, I want to provide a USB host interface based on WICED design. I will use the USB OTG of STM32F205 to provide it. But I can't find WICED SDK provide the USB driver. Does WICED provide the usb OTG API for STM32F205? Thank you.
Best Regards,
Jerry
