Studio Bluetooth Forum Discussions

Hi,

I have a MCU to connect Cybt-343026-01 via puart. I want to upgrade bt modul’s FW. For example, puart receive a defined command, then transmit the needed fw data via puart. Is it Ok? I know I can use HCI uart command, but now I just connect mcu to bt via puart. and I see “wicked-hci-protocol” and “hci-uar-spi-bridge“ exampl, need SPI? I’m confuse.just connect mcu to bt via puart ok or no? or need other hardware pin needed?

Hi,

We have developed a medical device with cyw20719 bluetooth chip. we want to go for FCC compliance certification testing.

In FCC testing we want to change some Bluetooth settings like TX POWER and HOPPING SEQUENCE.

Kindly provide any tool or documents useful for this testing.

Thanks,

Hello,

I tested the A2DP sink function using "snip.bt.a2dp_sink" in WICED-Studio-6.4.

Program to CYBT-343026-01, connect the I2S output to the DAC (NXP UDA1334A), and output to the headset for playback.

The sound output has a noise, once every four seconds, pronounced like "po".

I have tried programming to CYW920706WCDEVAL and the situation is the same.

Is there any experience in solving this? What parameters can be improved?

Hi,

I have a requriement want to have a confirm. There are bluetooth A and B C D. BT A searched B, then create communication with B and transfer data with B. Then can BT A still search other devices such as C, D simultaneously?(which means A communication with B and at the same time , A search tag C and D).

I now have cybt343026-01 module, other module will be OK for above function.

Hi

     I am using the CYW920719Q40EVB-01 evaluation kit

     I already finish the following items.

     1. Create a new project in WICED with just one file which is empty:

     #include "sparcommon.h"

     APPLICATION_START() {}

     2. Download this project from WICED onto your board.

     I could sending commands with CyBluetool, and received the correct event.

     11/28/19 18:09:19.115  com8 <c Reset

       HCI Command Complete Event

     com8@115200

     [0E 04 ]: 01 03 0C 00

     event = 0x0E (14,"Command Complete")

     Num_HCI_Command_Packets = 0x1 (1)

     Command_Opcode = 0xC03 (3075, "Reset")

     Status = 0x0 (0, "Success", "Success")

     But if i use other UART console AP, sending the command "01 03 0c 00"

     Why i can't receive any feedback by UART console AP?

     Have any other setting or initial command to do?

Hi :

   today I meet a strange question that my CYW920735Q6EVB-01 board can't print debug message. I have verified the Uart hardware is good, and the Baud rate is correct.

I use the SDK version is 6.4.61

I use the  WICED_BT_TRACE("XXXXXXXXXXXXXX", )  to  print the debug message , but it can't print the message

but I can use the  HCI UART to download firmware

thanks!

During the loading of an application to the CYBT-343026 module (20706 based), are there any parameters that can be given to Chipload.exe to set the BDADDR of the module?  The application is based on the headset demo app.

Is there any way in the headset application (on a CYBT-343026) to determine the cause of a disconnect from a phone.  There are 2 things we'd like to determine:

1) did the disconnect come from the phone actually terminating the connection by shutting down a music app or disconnecting in the Bluetooth settings?

2) did the disconnect occur because the phone went out of range and cannot be "seen" anymore.

Based on the type of disconnect, I need to determine if I should accept the disconnect or try to reestablish the connection.
