Wi-Fi Combo Forum Discussions

I am trying to implement a USB 2.0 host for a custom class on a CYW54907 wireless SoC (CYW943907AEVAL1F dev board). I would like to connect the host to a custom class on a USB device running on an FX3 module (CYUSB3KIT-003 EZ-USB® FX3™ SuperSpeed Explorer Kit).

I am using USBX dpump to create a custom class on the host (see attached code). I also added dpump to the event handler in wiced_usb.c (attached). On the FX3 device, I am running the default BulkLoopAutoCpp example. I have also tried running the MouseDemo on FX3.

I cannot get the custom DPUMP class to work. I notice that when I plug the device in, the event callback function (wiced_usb_host_usbx_host_evt_callback) in wiced_usb.c does not trigger. I suspect the reason is that the UX_HOST_CLASS class instance NULL? I get the same result when I test with default USBBulkSourceSinkLED example on FX3 (the LED doesn't even light up). Here is the terminal debug terminal output from this test:

+-------------------------------------------------+ + USB20 Host DPUMP Custom Class Application       + +-------------------------------------------------+ > USB20 Host init starting... Detected board strapping is in USB-PHY mode!! Detected board is in USB Host mode!! USB Host support 2 HCI resource USB20 Host init completed!!! #UX#: Device: . State: 1 . Address: 1 .

Max Power: 250 loopback +++START: DPUMP custom class loopback started *** Please input any key from your terminal program *** DPUMP == NULL ---END: DPUMP test

I also checked the MouseDemo with the same host – it enumerates as an HID device, and successfully executes the event callback function (see red). (It also prints data successfully when run with hid_keyboard host app). Here is the terminal output:

+-------------------------------------------------+ + USB20 Host DPUMP Custom Class Application       + +-------------------------------------------------+ > USB20 Host init starting...

State: 3 . Address: 1 . HCD name: ux_hcd_ohci . Class name: (null) . Speed: 0 (LOW) . Port Index: 0 . Max Power: 250

Could you please assist me in getting a custom class to work?

Many thanks in advance.

Hi,

Currently using Neb1DX and I am trying to update BT UART speed from 115200 to 3000000 .

After some searching and reading I found the function bt_host_update_baudrate in bt_firmware.c file.

When I trying to call this function I get Error 85 and 86.

I have some questions:

1. This funtion works?

2 When I need to update the baudrate update command? after wiced_init ? before?

3. is there another working function ?

When I call after wiced init but before BLE init : [setBaudRate 85] VERIFY FAILED

When I call after BLE init: [setBaudRate 86] VERIFY FAILED

Thanks,
David

respected sir/mam

now, i'm using CYW54907 and initialize WiFi Access-point in this board. and i'm able to analysis WiFi beacon frame in wire-shark software.

now, i need to add my own Tag(IE = information element) in my WiFi.. so, i want to know that is there any kind of API function or any suggestion from you.. like how can i add my tag.

i used custom_ie Example already but it's for specific Vendor IE.. like there is element ID = 0xDD.. we cant change it form function change in wiced. it's not for custom IE exectly..

how can i add my own IE tag..

thank you

I am using two bcm 43438A, the two devices are putted into a shield box, then I  tested them in wifi mfg mode. One device sends 1000 package, the other one only receives around 960 packages.

Below is the  wl version

# wl ver                                                                                                                        

6.37 RC32.0

THE SENDER COMMANDS

1. ifconfig wlan0 up

2. wl down

3. wl mpc 0

4. wl country ALL

5. wl up

6. wl scansuppress 1

7. wl band b

8. wl channel 7

9. wl nrate -r 11

10. wl txpwr1 -o -d 30

11. wl pkteng_start <MAC> tx 100 1000 1000

12. wl phy_forcecal

THEN RECEIVER COMMANDS

1. ifconfig wlan0 up

2. wl down

3. wl mpc 0

4. wl country ALL

5. wl up

6. wl scansuppress 1

7. wl band b

8. wl channel 7

9. wl nrate -r 11

10. wl frameburst 1

11. wl phy_watchdog 0

12. wl pkteng_start <MAC> rx

13. wl reset_cnts.

wait 1000 packages are transmitted.

14. wl counters | grep pktengrxdmcast

The result: only around 960 packages received. What may cause this problem.

Hi - I got cypress board with STM32 mcu. I read OTA pdf and it has memory map two option: External or internal+external

How to know what combination used by my application?? I want to know memory map of my current application. For example where is bootlaoder and size, DCT and size, application and size, factory app and size etc. Also I want to know where it is stored (internal or external). How to trace it?

I dont know currently what configuration used by my app. I do OTA successfully but don't know where application got stored???
