Hi,Communites, I have a question about Company-ID part of Bluetooth Device Address

According to the KBA211407 as below,
https://community.infineon.com/t5/Knowledge-Base-Articles/Setting-Bluetooth-Device-Address-KBA211407/ta-p/248632

my customer got their Company-ID form the Bluetooth SIG, but that has only 2-byte(16-bit) value.
I think Company-ID should be 3-byte(24-bit) value.
Is it OK that they add "00" to the upper side of the value?

Hi,

I'm using psoc6 with bless and mtb2.4.

I want my devices in peripheral mode to accept connection from public device adress and Random device adress.

I'm now able to do this in my code if i know before wich device will try to connect ( public or RPA)

In case of public address I set  Cy_BLE_SetAddressResolutionEnable to false and it works.

In case of RPA i set Cy_BLE_SetAddressResolutionEnable to true and it works.

My question is the following : I need to allow connection from all kind of devices (public and RPA). Do I need to set Cy_BLE_SetAddressResolutionEnable to true? How can i add Public device address to Resolving List ? (that's what I do but it's not working...)

Thank you for your support,

Regards

Hello, I am using the CYBLE-333074-EVAL-M2B AND CYBLE-343072-EVAL-M2B boards in mpodus tool box v3.0,
the problem is that these boards do not have the RFCOMM Serial Port example,
I need to use the RFCOMM Serial Port example on these boards CYBLE-333074-EVAL-M2B AND CYBLE-343072-EVAL-M2B,
can you help me?
it is urgent

Dear supporters,

I am designing an IOT product using CYBLE-014008-00.

I have some questions.

1.BEL module placement

Is the A-2 configuration preferable to A-1 when placing a BLEmodule down below?

Or,Are the characteristics of radio wave the same for both A-1 and A-2?

2.Effect on capsensing

If a sensors for capsense are placed near the antenna on the BLE module, will capsensing be affected by BLE radio waves?

Is it better to place sensors as far apart as B-2?

If B-1 and B-2 are not recommended , could you give me some advice about recommended sensor placement?

I am using a CYBT343026 module, controlling it via EZ-Serial.

I use bt_start_inquiry to find BT/EDR devices. I see that some devices return both bt_inquiry_result and bt_name_result while some return only the former, providing no device name.

When I enumerate the same devices with my PC/Phone I see their names. I suppose that the PC/Phone sends LMP_name_req requests for those devices.

How can I do the same via Ez-Serial?

I tried bt_query_name, but this seem to work only for devices that already return a valid name.

Is there a way to retrieve device names for BT/EDR devices that don't expose it in their inquiry reply but just on request?

Thank you in advance for your support.

I tested with FW 1.2.27 and 1.2.29.

Hi Team

I am looking for an alternative to a Bluetooth module (PN: BT121 @ Silicon Labs). 

Our Requirements are: 

1. It should support both BLE and Bluetooth Classic. 

Kindly suggest to us if any part is available in Infineon. 

Hi, 

Because of the standard Serial Port Profile (SPP) is not supported by BLE, i need to create a BLE custom service to be able to send/receive UART data over Bluetooth.  I want to transfer uart data over bluetooth(psoc6 to PC Serial Comport). Is there a reference project to do so.

Thank you.

Hi again,

Dont't knwo why but I can't reply in my own thread (https://community.infineon.com/t5/AIROC-Bluetooth/CYW20719-Core-Dump/m-p/394497#M2966) because it is some how locked.

Well, the answer is not the expected answer...I know how to use a core-dump using GDB or other tools. The initial question is that the 'core dump' (term wich is used in the topic https://community.infineon.com/t5/Resource-Library/CYW20719-and-CYW20735-Clocks-RTC-WatchDog-Timer-Application-Timer-and-PWM/ta-p/246352) is send using some Vendor HCI events (0x04 = HCI Event, 0xFF = Vendor Specific event, 0xF4 = event length)...This is NOT a 'common' core-dump as we all know. It's a Cypress/Infineon specific core dump generated by the ROM usinga function like dbfw_coredump_exception_cm3 or dbfw_coredump_exception_cm4.

I've been able to find the meaning of some events content by both looking at the 'headers' and also by exploring the internalblue tool code (https://github.com/seemoo-lab/internalblue) and build a tool which is almost complete. The only missing part is the CPU registers which I was able to dump because the addresses are common to me (the ARM Cortex-M series registers addresses).

I'd like to know if there's an official tool which would properly decode the received Cypress/Infineon specific core-dump send over the HCI uart, and would help us debugging what is happening. 

Regards,

I am using Creator since the new BLE stack and OTA for MTB is not yet available. My project uses an upgradable stack and a minimal bootloader app. Is there anything that will keep me from updating my Creator based project to a MTB based project using BLE OTA? If it can be done, is there anything that needs to be accounted for on the bootloader app to make sure it will load the BLE stack app and main application app? 

Thanks for the help!
