Studio Bluetooth Forum Discussions

Hi all:

   as we know, the wiced studio can download the firmware for CYW20735 by the uart., however  this way to download  firmware is not applicable to the Factory firmware burning. so we should develop a Host computer for firmware burning. firstly ,I need

to know how the wiced studio download the firmware, the console output messages is below when I use wiced studio to download firmware:

Detecting device...
Device found

Downloading application...
Download complete

Application running

where I can get the code of firmware downloading！

thanks！

Hi,

I am looking for a way to get the randomized Access Address for BLE data packets (LE piconet physical channel).
Is there any way to extract the randomized Access Address from Cypress's API?

Thank you

Hello!

Would you mind answering the following questions about the module?
1. Does the chip support Dual BLE sending and receiving at the same time?
2. How long can we buy this module?
3. Is there functionality for production testing?
4. is there a built-in DSP for sound processing?

5. Power consumption?

Thank you!

First query:-
  1. I am using CYBT-413034-EVAL evaluation board. I have programmed with hello_client application present in 
20719-B1_Bluetooth/apps/demo. When I reconnected the board to the PC after programming, initially some unknown (junk) characters are 
visible on PUART (Peripheral UART).  I do not want these characters to appear, please help.  
2. Same thing has happened when I loaded with 20719-B1_Bluetooth/apps/demo/hello_sensor application.  

I have WICED-Studio-6.2.1.2-IDE installed.  

Second query:-  

I have one doubt. When I program hello_client or hello_sensor or any other application to say, I see unknown characters 
on HCI UART. I know that HCI UART is used for programming. Just wanted to know what these characters are meant for. 

Thanks in advance for the reply.

This question follow my last one which has been marked as solved by someone else :

WICED HCI Download firmware to ram using client control

I successfuly download to RAM my own software using ModulToolBox ClientControl on windows and a .hcd file build from Windows

I am also able to download to RAM the same ".hcd" file build from windows on a client control running on linux.

I use sdk v1.4 on both setup.

I have compare my .hcd build from linux to the one from Windows,

Has i understand my Client Control error "10-30-2019 17:58:24.756: Wrong HCD file format trying to read the command information" came from the linux generated .hcd file which as the following issue :

Most of the third byte of the WRITE_RAM command have for value 0x18 on the ".hcd" file generated from linux

The ".hcd" file generated from widows have for the same third byte most of the time value 0x14

What is wrong with my setup on linux ?

I also try to compile my own version of Client Control on linux but the build fail since the source code does not include the following file "protobuf_rpc.h" :

client_control/source/nanopb/protobuf_rpc.c:3: error : 'protobuf_rpc.h' file not found

Thanks

In ubuntu 16.04, the hard disk space has about 10G free space, but the installer issue there is only 1G free space.

From the documentation snapshots, it appears there are headset example apps for the CYW920719 board in WICED. I am not finding them in my file structure -- have they been removed from the distribution?

how can i do this? may i use ez serial firmware on SLAVE module and create an application on MASTER to manage the connection with them ? could suggest me some examples to start, or other ways to solve this issue?

Thanks in advance

I set the module to the observe mode and receive the contents of the packet on the BLE.
However, the number of data collected is very different from the current number of BLE.

In fact, there may be 1000 BLE packets in 10 seconds, but my UART only shows 5~6 packets.
Does anyone know how this is going to happen?

Is there a filter function in the API that isolates some of the packets?
The picture is that I use the APP on my mobile phone to retrieve it.

The sending period of the BLE device is about 100ms, but I don't seem to receive the content.

I platform is WICED_STUDIO 6.4.
