Hi all.
I am trying to setup AP mode for 5GHz with channel 40MHz. Module 2BC from Murata
My config hostapd.conf:
interface=wlan0
ssid=CYW_4373
beacon_int=50
#ctrl_interface=/var/run/hostapd
driver=nl80211
max_num_sta=5
channel=36
wpa=2
wpa_pairwise=CCMP
wpa_passphrase=12345678
wpa_key_mgmt=WPA-PSK
hw_mode=a
ieee80211ac=1
ieee80211n=1
### IEEE 802.11ac
# VHT (Very High Throughput) 40
ht_capab=[HT40+][SHORT-GI-20][SHORT-GI-40]
vht_oper_chwidth=0
wmm_enabled=1
when I try to start hostapd, the point does not rise
What could be the reason?

How many stations or connections can each WiFi silicon family support without major modifications?
What physical features may affect the number of stations or connections?
- Based on a previous post, available memory plays a role.
- https://community.infineon.com/t5/Wi-Fi-Combo/Looking-for-details-regarding-CYW43455-concurrent-Station-and-AP-operation/td-p/122651
Does Infineon have a table that lists individual capabilities of each WiFi silicon?
- When selecting the base silicon in a radio, understanding I'll be using a partner module, it would be helpful to know any limitations to the number of potential stations or connections.

Show LessHi Sir
as the page , Infineon has many solution for Nvidia .
https://www.infineon.com/cms/en/partners/partner-news/nvidia/
May I know any WIFI6/WIFI6E solution that in Nvidia AVL?

When i jsut connect cyw43439.
I'm check for pinout using osiloscope
Sleep Clock, VDDIO, WL_REG_ON, BT_REG_ON all is okay.
stm32 chip on cts(connecting to cyw43439(rts pin)) it LOW
but stm32 chip on rts(conneting to cyw43439(cts pin)) it is high.
How to solved problem?

const uint8_t reset_buff[] = {0x01, 0x03, 0x0C, 0x00};
const uint8_t minidriver_buff[] = {0x01, 0x2E, 0xFC, 0x00};

HAL_Delay(100);
HAL_UART_Transmit_IT(&huart2, (uint8_t *)minidriver_buff, sizeof(minidriver_buff));
I'm tired reset, download_minidriver.
When i check osilioscope, maybe it was worked.
So Can i firmware intall w_bt_firmware_controller.c for opcode?
Hi Sir,
please provide CYW43439 pcb stack info.
thanks.
Best Regards,

If i create cy_rtos_create_thread. My all rtos thread broken.
Hello. I am wondering if the CYW55573 can be used with the stm32 according https://github.com/Infineon/AIROC-Wi-Fi-Bluetooth-STM32. And if yes, which stm32 series would be best and which development board? Also, should the CYW55573 be used in a module such as the Sona IF573
Show LessWhen i run ble_hello_sensor, I'm falled HardFault_Handler.
I think cy_rtos_create_thread(cybt_platform_task.c) for TX task, RX task.
I think stop point.
This time not called hardfault_handler but can't init bt_start_fw_download.
help me...
