Hi,

I am using a CYBT-343026 Bluetooth module connected to a MCU for wireless communication.

First step, the connection is Bluetooth serial port link only. The device can be found and paired. But we have a couple of questions to ask.

1. The friendly name is given by the MCU, most time the module does the advertisement with it no problem. However, I did see sometimes the friendly name is somehow seeing corrupted when a mobile scanned it. 

2. The module can be paired and connected. The connection seems not very stable and on mobile side, I can see it shows connection lost, and when tried to reconnect, it shows connection failed: read failed, socket might closed or timeout, read ret:-1

3. When connection is good, if I typed into the module from mobile side, it seems that the outgoing stream is affected, or even stopped. Is there any buffer issue there?

Thanks in advance for any help

Hello,

I am working on updating the EZ-Serial Module Firmware over OTA for the CYBT-343026 device. I'm using the image from CYBT-343026-01-EZ-Serial_v1.2.38.0.zip. I noticed that there are both .bin and .hex files available. While I was able to use the .bin file, I couldn't use the .hex file. Could you please explain the purpose of the .hex file?

Thank you in advance for your assistance.

Best regards,

Kazuki

We are using the EZ-serial firmware V1.2.36 of the CYBT-343026-01 module. After power on of the module I use an android device to connect to the BLE peripheral interface for Unacknowledged data. Connection succeeds, but serial data is not forwarded to the BLE connection unless ~50 seconds has passed or a full 20 characters are sent. The packetization mode is Anticipate (1) with default parameters (5 ms, 20 characters). What could be causing this 50 second delay? Its almost as if the 5 ms timer is not expiring.

I can send data on the BLE connection and it is transmitted on the serial interface immediately.

After waiting the 50 seconds after power on then serial data is transferred over BLE without delay.

If I change the packetization mode to Immediate (0) then the serial data is passed to the BLE connection with no delay.

Hello Infineon support team.

We would like to refer to a schematic of CYW920721M2EVB-03.

Could you provide the schematic?

Thanks,

Hi~

I'm considering about the CYW20736 chip for suggesting for my custonmer.

But, I've found there  is no internal flash. So I need to double-check for confirming that whether it can use without external memory or not.

It's is very important for me, because my customer want to know that he can upload the custom binray without external memory.

I know there is internal ROM sized 320Kb. But as my thinking,  I cannot write my application data on the ROM.

Please clarify that cunfusing.

Many thanks

I have used the code examples to build a mesh network. The examples are 'Mesh Demo Embedded Provisioner' and 'Mesh Demo Dimmer Self Config.' When I press the button in the 'Mesh Demo Embedded Provisioner' to configure the Target as a Provisioner, it creates a network. When the other target with the 'Mesh Demo Dimmer Self Config' example is provisioned, it must save the network data. However, I want to know where it is saved and which function is responsible for saving the data. I have searched for it, but I can't find it. It's the same when a 'Mesh Demo Embedded Provisioner' connects to the network; I don't know where the network data is saved.

Hi,

when Im using HFP handsree example code,  we are facing issues

1.In the handsfree_connection_event_handler function , we commented status  as I mentioned in below snippet as we observed that clip event is not happening (when we connected Bluetooth headset clip event is happening)and audio is going to connected mobile device 

2. In the handsfree_connection_event_handler function ,Without commenting status as I mentioned in below snippet as we observed clip_event event is happening(connect or without connect bluetooth headset) but the audio is going to our cypress module(cybt 413061).

we require both clip event (without connecting Bluetooth headset)and audio has to go to connected mobile device , what changes can I do to achieve this functionality.

Regards and thanks

Hi Infineon team,

I just had a few queries. I am going to purchase CYW920706WCDEVAL for my project.

1. With the CYW920706WCDEVAL evaluation kit, what would be a suitable external antenna?

2. Which Revision of Arduino would be compatible with CYW920706WCDEVAL?

Kind regards,

Remo

Hi,

I need an example with a Central role with bonding list that can be stored and deleted on a specific event ( receiving parameter on uart).

Thanks

Hello

I am using the PUART on a CYBT-343026 (CYW20706) to send/receive data to a Host MCU with CTS/RTS flow control. The Host MCU sometimes blocks the flow of data from the CYBT to the Host MCU by pulling the CYBT's CTS pin high for extended periods of time.

This behavior is expected and is simply how the Host MCU operates.

However, when the CYBT's CTS pin is pulled high by the Host (thus preventing the CYBT from sending PUART data) the CYBT freezes and becomes completely unresponsive. After 4 seconds of its CTS pin being pulled high, the system watchdog timer causes it to reboot. While disabling the system watchdog timer prevents the CYBT from rebooting, it does not resolve the underlying issue.

My question is:
Is it accurate to say that the BTSDK PUART driver on the CYW20706 blocks the entire system as long as the CTS pin is held high?
