Hi Sir
May I know how to disable/enable internal/external lpo of CYW55573?
Customer use PCIE interface to HOST, and the LPO_IN is NC .
we knew that some of product can use internal RTC clock for LPO , but we want to know more about it of CYW55573 .
We would like to know to disable/enable internal/external lpo of CYW55573? what clock is for internal LPO ?

Hi Team,
We are using CYW43439(AW-NM512) in our design, here we are using Linux 5.10. Here we are able up and configure WiFi, which is up and running properly.
But, Bluetooth is not getting up we are getting below error for few command.

Also Find DTS entry as below:-

pinctrl-names = "default";
uart-has-rtscts;
/* resets = <&bt_reset>;*/

bluetooth {

shutdown-gpios = <&exp2 10 GPIO_ACTIVE_HIGH>;
clocks = <&osc_32k>;
clock-names = "extclk";
max-speed = <2000000>;
};
};
Let me know if we are missing any thing.
Show LessTo connect a set of sensors wirelessly, without a Gateway/Server, what solutions does Infineon recommend?
I'm interested in Wireless Mesh Networks that Infineon provides support for - such as WiFi Mesh, IBSS, Ad Hoc
I'm also interested in Wireless Mesh Networks that Infineon directly supports with examples - such as BLE Mesh
Show LessHello,
I cannot find the CLM power templates guided by AN225347.
It used to be available for download as a zip file.
Could you please direct me to where I can download the CLM power templates?

Dear Infineon,
We tried to use the command to enable BLE and 2.4GHz Wi-Fi signals at the same time, but we can only see the 2.4GHz Wi-Fi signal in the spectrum analyzer. If we disable 2.4G WIFI (wl down), the spectrum shows the BLE signal.
How to enable BLE and 2.4GHz WIFI signals at the same time in the spectrum? Thanks.

Hello,
We are doing Bluetooth regulatory tests for our product based on CYW43353 chip. We would like to start a transmission test on a fixed channel with a given modulation and pattern. Reading other discussions on this topic I've noticed the Set_Tx_Carrier_Frequency_ARM command that seems to be a possible solution.
We would like to understand if this command is only a "configurator" command or if this command actually starts a transmission.
Moreover, I'm experiencing some difficulties on understanding how to get an hcitool "CLI command version" from CyBluetool. I would like to understand how to transform the output in the log console to a command that I can issue on a bash console in the SOM that is using the CYW43353 chip.
Could you please give us some guidance on this? Thank you.
Show LessHi,
I can't reply to the thread below, so I'm creating a new question.
https://community.infineon.com/t5/AIROC-Wi-Fi-and-Wi-Fi-Bluetooth/CYW4373E-Hang-up-of-farmware/m-p/393706/emcs_t/S2h8ZW1haWx8dG9waWNfc3Vic2NyaXB0aW9ufExDWlpUU1BYVkNJMEZCfDM5MzcwNnxTVUJTQ1JJUFRJT05TfGhL#M1912
Am I correct in understanding that if the firmware hangs, there is no way to know and initialize the LSI?

Hi,
I am using Wiced 6.6 for one of our BLE based application. I am implementing new Custom GATT services and characteristics. I am using nRF connect mobile app as client and our device as server . I have created a GATT service and its characteristics with read, write, notify, indicate properties.
I could perform read , write command and notify operation. However, for the write request client is not receiving the response from server i.e. our device. Using wiced_bt_gatt_send_response API in Gatt_Write_Attribute_remote to send response for write request.
I have also observed below are available GATT Attribute Request Type in wiced BLE stack library.However, callback functions are available only for read, write, MTU, Confirmation. Callback functions are missing for WRITE_EXEC, PREP_WRITE request type.
/** GATT Attribute Request Type */
enum wiced_bt_gatt_request_type_e
{
GATTS_REQ_TYPE_READ = 1, /**< Attribute read notification (attribute value internally read from GATT database) */
GATTS_REQ_TYPE_WRITE, /**< Attribute write notification (attribute value internally written to GATT database) */
GATTS_REQ_TYPE_PREP_WRITE, /**< Attribute Prepare Write Notification (Suspending write request before triggering actual execute write ) */
GATTS_REQ_TYPE_WRITE_EXEC, /**< Execute write request */
GATTS_REQ_TYPE_MTU, /**< MTU exchange information */
GATTS_REQ_TYPE_CONF, /**< Value confirmation */
};
Looking for insights on this topic.
I know , it is recommended to use Modus Tool Box for new designs, However this exiting device where already wiced6.6 had used.
Regards,
Lokraj
