Wi-Fi Combo Forum Discussions
I am trying to get the GCI interface working between the 43907 based 1gc and the 20707 based cybt353027-02. I have flipped the low bit in the board flags for the 1gc nvram.txt and I can see the gci messages being sent out. I have also called wiced_bt_coex_enable() in the bt firmware.
I have j6:38 and j6:39 (rf_sw_ctrl_8, and rf_sw_ctrl_9) of the 43907 dev board connected to gpio_5 and gpio_6 (of the cybt353027-02.
The bluetooth board doesn't seem to be enabled for gci as there is nothing coming out of the bluetooth seci_out.
Am I missing something?
Show LessHi.
I found next combos for CYW43907: ThreadX-NetX, ThreadX-NetX_Duo and FreeRTOS-LwIP. Which combo has best performance?
I worked with FreeRTOS and LwIP on STM32 uC before. Is there reason switch to ThreadX and NetX combo for me?
Thanks.
Show LessI am using the AES-BCM4343W which includes the STM32F411 MCU (512KB FLASH and 128KB SRAM).
My application is utilizing both Bluetooth and WiFi and I am running up against the SRAM limit. I tried suggestions I have found in the forums, but these have not had any success in reducing SRAM usage. I am using WICED Studio 6.1. Any suggestions would be appreciated.

Just a simple question. Should the WL_REG_ON pin of CYW4343W be driven to VDDIO or VBAT to enable WiFi? I think its VDDIO, however its not 100% clear to me from the data sheet that this is correct. Just looking for confirmation on that. Thanks.
Show LessWhat specific examples and lessons learned are available for setting up secure WiFi enterprise connections using BLE?
Are there issues trying to pass certificate via BLE applications?

Show LessHi,
Test with sdk-6.1:
Using wiced_bt_ble_observe() API always get scan response even with
setting scan_mode =BTM_BLE_SCAN_MODE_PASSIVE in ble_scan_cfg.
It was working in sdk-6.0.1. So this is a regression in sdk-6.1.
ps. I remember I had reported such issue a long time ago and it's fixed.
No idea why this happen again in sdk-6.1.
Show LessHi,
I want to use the buffer pool statistics API based on the documentation in "Application Buffer Pools". This function doesn't seem to be generic as it is only defined in the include directory for BCM devices. Is there a way to monitor these pools otherwise? I need to monitor a peculiar GKI exception behavior[ out of buffer] I have observed in run time! I am using WICED 6.1.
Show LessHi. With new board design we can connect to CYW43907 mcu with J-Link)
What options need configurate in make file for custom board?
What platform need specify in build target name? For example "User.MyProject-CYW943907AEVAL1F JTAG=jlink download run".
Thanks.
Show LessI have an application I have written that has 2 simple functions taken from snips and samples in the wiced SDK 6,2. I am running the code on the BCM94343W_AVN.
A link to my application is included at the bottom of this post.
After connecting to the network there are 2 function calls in the application_start()
sendMessage(); // This function does a SSL Post of a message using the http_client
sensor_application_init( ); // This function Initializes the BT Stack and then observes for beacons.
If these lines above are commented out one at a time, the application and each function independently works fine.
However, If they are both enabled then the http_client will break and not connect and the bluetooth will no longer observe?
I have tried increasing the application stack, but I am stuck as to why these will not work together. The purpose of using a combo chipset was so that I could use both BT and an http client at the same time.
You can either use my code below and add your wifi info or take the snip.httpbin_org and initialize the BT Stack with something like wiced_bt_stack_init(). Of course you need to include the necessary dependencies.
