Hi, 

I am using CYW20706 in BLE mesh project "Mesh_Snip_On-Off_Server", 

The below is BSP version.

I have some efficient issue about mesh data transmit .

When devices are provisioned.

There are very high frequence data can't reach target device.

I want to config :

1. advertising interval

2. scan interval

3. TTL (Time to Live)

But I can't find the correct place to config these parameter.

Could you teach me where to config parameter and any suggestion to improve transmit efficiency.

Thanks a lot.

Hi Infineon team,

Would you be having any SPICE model for CYBT-343026-01?

The module is to be used in an Intrinsically Safe application, and the internal capacitance/inductance needs to be known.

Kind regards,

Remo

When we debug HCI interface for implemnt BT function, and when we met abnormal, we may always want a golden sample for reference. So I provide sunch a example for reference.

I use CY8CKIT-062S2-43012 run below code example. btstack-integration 4.6.0.2331; btstack 3.8.0.18197

https://github.com/Infineon/mtb-example-btstack-freertos-hello-sensor

I use Saleas Logic8 to captcure the HCI signal. See attachment. I also attach the WICED HCI UART Protocol for reference.

From the log, you can see CYW43012 receive command sequence like below:

1.HCI_SESET

2.DOWN_MINIDRIVER

3.WRITE_RAM...repeat many times

4.LAUNCH_RAM

5.HCI_SESET

come here, now the BT FW start run in the BT MCU. The following HCI command from stack you can parser it according HCI SPEC

0x01 0x01 0x10 0x00,   HCI_Read_local_version_Information

....

Hello

I am using the PUART on a CYBT-343026 (CYW20706) to send/receive data to a Host MCU with CTS/RTS flow control. The Host MCU sometimes blocks the flow of data from the CYBT to the Host MCU by pulling the CYBT's CTS pin high for extended periods of time.

This behavior is expected and is simply how the Host MCU operates.

However, when the CYBT's CTS pin is pulled high by the Host (thus preventing the CYBT from sending PUART data) the CYBT freezes and becomes completely unresponsive. After 4 seconds of its CTS pin being pulled high, the system watchdog timer causes it to reboot. While disabling the system watchdog timer prevents the CYBT from rebooting, it does not resolve the underlying issue.

My question is:
Is it accurate to say that the BTSDK PUART driver on the CYW20706 blocks the entire system as long as the CTS pin is held high?

best regards,
Niels Sparre

Hi.

I am currently using Laird LWB+ CYW43439 with WHD successfully in AP and STA modes.

But now I would like to use it in WiFi Direct/P2P mode.

Is it possible to use Laird LWB+ CYW43439 and WHD for WiFi Direct/P2P mode? If so, what would I need? are there any examples?

Thanks in advance.

Tool: modustoolbox 3.1
Platform: CYW920719B2Q40EVB-01
HID device role.

1. Issue
I connected to Win10. HID worked well. I let it last weekend.
Today morning I found that HID is not working (No data is transferred to Win 10) even it is connected.
So I had to restart.

2. Log
Last message was WICED_BT_HIDD_EVT_PM_FAILED. I think it is related with sleep control.
I have no idea how I avoid this situation. Can you help me with this?

wiced_sleep_config_t hidd_link_sleep_config = {
. sleep_mode = WICED_SLEEP_MODE_NO_TRANSPORT, //sleep_mode
.host_wake_mode = 0, //host_wake_mode
.device_wake_mode = 0, //device_wake_mode
.device_wake_source = WICED_SLEEP_WAKE_SOURCE_GPIO | WICED_SLEEP_WAKE_SOURCE_KEYSCAN | WICED_SLEEP_WAKE_SOURCE_QUAD, //device_wake_source
.device_wake_gpio_num = 255, //must set device_wake_gpio_num to 255 for WICED_SLEEP_MODE_NO_TRANSPORT
.sleep_permit_handler = APP_sleep_handler, //sleep_permit_handler
#if defined(CYW20819A1) || defined(CYW20820A1)
.post_sleep_cback_handler=NULL, //post_sleep_handler
#endif
};
SLEEP_ALLOWED = 1

Thanks.

Hello all,

I am using CYBLE212020-1 module https://www.infineon.com/cms/en/product/wireless-connectivity/airoc-bluetooth-le-bluetooth-multiprotocol/airoc-bluetooth-modules/cyble-212020-01/ .

I am using CYBLE stack 3.30 and my application is used to detect beacons. I would like to understand if there is a limit from the BLE stack regarding the maximum number of beacons that can be detected. 

Thanks,

Anusha

Hi Sir

 I would like to  set the ED (energy detect) threshold of adaptivity?
* How to activate ED?

Thank you
