Hi Communities,

We are planning to use CYBT-343026-01 for making an application using HFP and AVRCP.
Is it possible to make an application using HFP and AVRCP with CYBT-343026-01?

According to the QDID, I checked the launchstudio as below, but I could not find HFP and AVRCP in the supported layers.

If CYBT-343026-01 is not appropriate for the application, are there any other suitable devices?

Best Regards,

Is the CYW89820 module designed to perform HCI_RESET at the stack level when a hardware error occurs? Also, what does Hardware Error code 0 mean? Could you please explain the structure?

#1 Event from HCI. Name: HCI_Hardware_Error (Hex Code: 0x10 Param Len: 1)
#2 Hardware Error Code : 0 (0x00)
#3 HCI CMD SENT [0] Command to HCI. Name: HCI_Reset (Hex Code: 0x0c03 Param Len: 0)

Hi.

I use the CYBT-413061 module (CYW20721B2) on a custom board and try to run the RFCOMM_Serial_Port SPP demo in ModusToolbox 3.2. The code seems to load OK, but when starting the Client Control App and open the serial port, nothing happens - the controls are all greyed out. I then also run BTSpy and connects from a Windows 10 PC as suggested in the instructions - the Client Control App then seems to connect (not greyed out anymore), but nothing happens when pressing any buttons. BTSpy however, seems to display everything, like when hitting a key on Windows/TeraTerm BTSpy, it displays the messages - but nothing shows up on the Client Control App SPP tab or message window.

What could be wrong?

Regards, Roger

Hi~

I recently update MTB 3.2 from 2.4

I added some example for the 343026 BSP

But I cannot find client control application in tools category.

How can I solve the problem?

Many thanks

We are using CYW20704UA2KFFB1G BT device on the VIP6102 Android platform (with BCM SoC 7271) . When the BLE devices (example BT remote controller , headphone , mouse ) are in discoverable mode they are not getting added to visible list .  We could see the MAC address of the device. we see the error "no link key or ble key found" . 

Could you please suggest when we could get such error and if there is any possible way to solve it .
