Hi~

Our customer has to download Mass F/W download for each chips.

But, they are struggling with download speed consumption.

Their current download method is like as below

 Method :

                    1. Using 'cgs.exe' to combilne f/w and own BD Address. and then, make hex file.

                    2. After that, download firmware with chiploader.

                     3. Download in same time with CYW20719 as maximum count 15

They have to find a more efficient way.

Please let me know the proper way to solve that issue above.

Thanks alot

Hi, 
I am trying to add the Insulin Delivery Service ( UUID: 0x183A) which is one of the standard primary service as defined by Bluetooth organization. But I am unable to find the support for it in the Bluetooth configurator.

Is there a way to include a primary service which is not shown here ? Or the only way to add is to create a custom service and add the characteristics manually ?
Thanks!

Hi there,

I just had CYBLE-343072-EVAL-M2B evaluation kit and I'm wondering if there's a UART example program available similar to the nRF5 SDK UART example program. I just need CYBLE-343072/CYBLE-333074-02 to pass on data coming via Bluetooth to UART, and vice versa.

Thanks.

Hi,

I use the CYBT-343026 chip in HCI command mode.

I send WICED Hci commands to control it.

Whenever I send a random character BEFORE I send a valid HCI command, the whole communication is not working anymore and I need to reset the device.

E.g. when I send a HCI Reset command  (HEX) 19 01 00 00 00  everything works fine and I receive a "Device started event" (HEX) 19 05 00 00 00

However, when I send a (ASCII) 'v' before sending a reset command, I will not receive any answer. Sending a valid command afterwards also does not fix this issue.

Is there any special setting that I need to setup to make the parser robust to "invalid bytes"?

Best regards

Alex

Hi, 

I am using CYW20706 as BLE peripheral, 

and using nRF connect App to connect 4 mobile phones as central, 

connect interval: 200ms, slave latency: 0, timeout 4800ms.

There did not do anything but only keep under connection.

Few hour later, there will happen disconnect and get the reason 0x08 supervision timeout.

After 2 devices disconnect with 0x08 and ohters 2 device still under connection.

I have read this https://community.infineon.com/t5/Studio-Bluetooth/Maximizing-number-of-connections-with-CYW20706/m-p/133129#M3267

He seems to can stable connect 4 devices.

Is there any suggestion?

Hello,

I am using a PSoC 6 and I would like to create a BLE connection and send data via BLE(GATT). Can anyone help please?

Thank you

Hi all,

I am developing an audio sink application for the CYBT-423060-02 module with ModusToolbox 3.0.0.

Since there was no sample program available in the "New application" wizard, I started from an empty app and worked my way from there adapting code from earlier modules and similar samples.

I am currently trying to store and restore Identity Resolving Keys.

I included the header  with
#include "wiced_hal_nvram.h"

And I am reading and storing the key with respectively :

wiced_hal_read_nvram(WICED_NVRAM_VSID_START+1, 65, &local_irk, irk_result)

and

wiced_hal_write_nvram(WICED_NVRAM_VSID_START+1,65,&local_irk, irk_result)

This should work as I can find the prototypes of the functions and the macros in 

mtb_shared\wiced_btsdk\dev-kit\baselib\20721B2\release-v4.0.0\COMPONENT_20721B2\include\hal

But when I try to build the app, I get :

'WICED_NVRAM_VSID_START' undeclared

and

implicit declaration of function 'wiced_hal_read_nvram'

I must be missing something obvious here...

Can someone point me in the right direction?

Best Regards

Hello Infineon support team.

This issue is similar to following case.
https://community.infineon.com/t5/Bluetooth-SDK/About-I2C-Master-SCL-frequency-on-CYBT-343026-01-CYBT-353027-02/m-p/286602

We are evaluating I2C behavior on CYW920721B2EVK-02 board. We implement following code to configure the I2C frequency 400kHz.
wiced_hal_i2c_set_speed(I2CM_SPEED_400KHZ);

However, the actual I2C clock frequency 356kHz is observed on our oscilloscope. Do you have any idea to see the actual frequency 400kHz?

Thanks,
Tayo

I was wondering which products in your company support the TBFC(Triggered Broadcom [Bluetooth] Fast Connect) function?

Could you please provide the relevant product models under production, as well as the access to these chip evaluation boards or download links?

I need the relevant IDE,SDK and hardware to develop these functions;
