Wi-Fi Combo Forum Discussions

When running FreeRTOS with powersave disabled, what clock source provides the tick through platform_tick_isr? Is it the external 32.768 KHz crystal, LPO, or is it derived from the oscillator that is internal to the 1GC module?

Out of thousands of devices shipped we are seeing one that has about 17% error and another that has about 10% error in a periodic scheduled event triggered through a FreeRTOS timer.

Hi, all.

I'm testing the Murata's BT/WLAN combo chip.
The dhd driver I apply is provied by Cypress, and supplicant and hostapd use the one provided by Linux.
I'm setting it up in two ways.
The first method is provided by Murata, and the second is provided by Cypress.

<AP>
killall wpa_supplicant
hostapd -B /etc/hostapd.conf

* IP is dynamically allocated through dhcp-server.
* udhcpd is not used because IP allocation uses dhcp-server.

<STA>
./wl join TEST_AP (: ssid name)
./wl assoc

If I set it to 5GHz band, the setting result is 802.11ac with BW 80MHz and NSS = 2 (Max T-put 867Mbps).
If I set it to 2.4GHz band, the setting result is 802.11n with BW 20MHz and NSS = 1 (Max T-put 72Mbps).

For 5GHz band, there is no problem as it is the maximum T-put setting.
The 2.4GHz band requires additional setting for max T-put (40MHz BW and NSS=2, 300Mbps??) but I don't know how.

I looked for setting in wpa_cli and chaning the hostapd.conf option, but it did not work.
(i.e wpa_cli -iwlan0 set_net 0 frequency 2437/40 @ for manual setting ,
option hw_mode, channel, 80211n, 80211ac option @ hostapd.conf)

Please can someone tell me how to set up to achieve max T-put at 2.4GHz band?

Best regards.

Hello,

I create a new topic as my previous one has been locked for an unknown reason.

Initial topic:

How to use GPIO external interrupt

My response to ZhengbaoZ_96

So what you propose is the same thing as the option 1 of my initial first message, except the fact you use SPI2 and I use SPI5. Could it impact anything to use SPI5 instead of SPI2 ?

I still don't have any interrupt with my code "option 1".

Thanks

Hello.

The Bluetooth Internet Gateway code example mentions that it supports CY8CKIT-062S2-43012 featuring CYW43012 radio (GitHub - cypresssemiconductorco/mbed-os-example-bluetooth-mesh-gateway: This code example demonstrates how to use Cypres… )

is it possible to use the above code example with CY8CPROTO-062-4343W featuring the CY4343W radio? since both radios support BLE mesh (43012 support B5 while 4343w support B4.1)

what do I need to modify in code example in these cases?

Regards

Karim

When the device itself is connected to "Central" and the other side (BLE module) is connected to "Peripheral", "BLE connection ⇒ pairing registration" is performed every time, even though there is connection experience.

It is likely that the bonding process has not been successful, so please investigate.

Please refer to the attached file "Report_03172020.xlsx" for details.

Hi,

I store network credential in the device, but it is plain text. Can you suggest alternative methods to store(not plain text). can it use same wifi dct structure?

Hi all,

I want to use internal uECC library, which I have enabled by including in the MakeFile : ota2_bootloader.mk, by adding: GLOBAL_INCLUDES  += ..\..\..\WICED\security\BESL\mbedtls_open\include\mbedtls.

I want to know how to enable the internal SHA256 library to be able to use the files: sha256.h and sha256.c. (location: 43xxx_Wi-Fi/WICED/security/BESL/mbedtls_open/include/mbedtls)

TIA!
