AIROC™ Bluetooth Forum Discussions

Hi,

We are using a CYBT-343026-01 (with CYW20706) for a customer project and use ModusToolbox V2.4.0 with BTSDK Release V3.2.0 to develop our own module software. 

One of the customer requirements requests to enable adjustment of the TX Output Power setting of the Link and/or Advertisment. We use the functions as described on page "Configuring Transmit (Tx) Power on CYW20706 Chip -... - Infineon Developer Community" to do that. However, the functions are only executed after the value used for TX output power value was previously set by a custom command and sequentially stored in the NVRAM. After this one time procedure, the value in the NVRAM will be read out and used after each boot up sequence of the module.

Due to a mistake, we did not particularly set the "max_pwr_db_val" in "wiced_bt_cfg_settings_t". We also didn't get any errors or warnings so it would pop in the eye during the build process. So for us it is not defined, what the value of "max_pwr_db_val" is.

As the customer already did some measurements and he wants to evaluate the impact on the measurements, we would like to know what is the default setting of the CYW20706 if no "max_pwr_db_val" was set. If there is no "default" value in the SDK , maybe due to configuration dependency (cgs or hdf-file), where can i identify the correct setting in the files to read out the default setting of the TX power settings.

Thanks in advance!

Hello Infineon Support team

We have developed an application for CYW920721M2EVK-02(Chip:CYW20721B2KWB9G) using ModusToolBox.
However our actual adoption chip is CYW20721B2KUMLG. In this case, we should do porting our application from CYW20721B2KWB9G to CYW20721B2KUMLG.
Please tell us the way to the porting using ModusToolBox? (I guess Makefile needs any modification.)

Thanks,
Tayo

The "Basic device firmware upgrade (dfu)" example ( https://github.com/Infineon/mtb-example-psoc6-dfu-basic ) does not work when compiled in Release mode.

Steps to repro:

- use ModusToolbox 2.4 (does not appear on 3.0)

- Create "New Application" -> "CY8CPROTO-062-4343W" -> "Basic device firmware..."

- Modify Makefile: "CONFIG=Release"

- Modify Makefile: "TRANSPORT_OPT=USB_CDC"

- make erase

- make -j program

Expected behavior:

- After programming the device, the device should enter into Bootloader mode.

Actual behavior:

- Device does not leave "reset" state... not sure what's happening TBH.

- But if I press the "reset" button, then the device will boot, and this time it will enter into Bootloader mode.

Observations:

- When compiled in Debug mode it works Ok.

And you'll notice that the 

Hi,

I am working with PSoC6 (CYBLE-416045), I want to use the Bluetooth functionality. I have a running code, which I want to test with the CySmart app - I tried the Cypress BLE Beacon which is  available on google play– but I can’t connect to the PSoC6. The PSoC6 bluetooth is visible on my smartphone, but not on the app. 

Is the app out of function, if so, is there any alternative?

HW: just get CYW920820M2EVB-01

SW: install ModusToolbox-2.4

lightblue on phone can find this device.--- the board works properly.

question:

Do i have to set  mode to "kp3-daplink"?

I fail to set mode to "kp3-daplink" and can set to other mode with no problem.

Hello,

Can someone please explain how wiced_memory_allocate() allocates the memory? 

I tried wiced_bt_create_pool() to create some pools and then checked using wiced_bt_get_buffer_usage(), but the pools stats don't change no matter how much I allocate or free using wiced_memory_allocate().. Where does the memory come from and where can I check how much memory I have left? Can I modify the size of the "dynamic memory"? And/or how I am supposed to use the wiced_memory_allocate()?

Thanks,

Jakub.

Hi all,

     I use function "wiced_bt_gatt_send_discover" to discovery characteristic_declaration of a service, but no event "GATT_DISCOVERY_RESULT_EVT" hanppened，No matter how the parameters change；

 Please help.   

type = GATT_DISCOVER_CHARACTERISTICS;

memset(&param, 0, sizeof(param));
if (uuid != 0)
{
param.uuid.len = LEN_UUID_16;
param.uuid.uu.uuid16 = uuid;
}
param.s_handle = 0;
param.e_handle = 0xffff;

status = wiced_bt_gatt_send_discover(conn_id, type, &param);
return status;

Please guide me how to use it correctly ，thanks！

Hi,

We are using the cybt-353027-02 module to build a headset. When listening to music from some phones there is a regular crackling sound. It is about once every four seconds. 

Most phones work ok and if I use another headset the "bad" phones sound ok too.

This post seems to have a similar problem, https://community.infineon.com/t5/Studio-Bluetooth/a2dp-periodic-audio-click-with-ios/td-p/332342   
The suggested solution there is to call a function called BTM_SetAfhChannelAssessment, but that function is not available for me.

Hello,

I cannot find any project files nor dev tools for Cypress CYW20730.

There is also written in the datasheet, that it "CYW20730 is a Bluetooth 5.1-compliant".

Was that an update in the series of the previous, Bluetooth 3.0 version?

Kind regards
