I would like to know how to use HID and voice mike devices on CYW20735?

Hi

Currently, Customer has encountered a problem that no response was given to

RESET_Command before writing FW in Pre-production.

They tried 11pcs module and 2pcs were failed by no respons.
And 9pcs have successfully recieved response.

Could you give us the reason for the failure and
the way to solve the problem?
BTW, this issue was happened in the customer MP line
so we can not test such complex test ,
such as "recovery mode" ,unfortunately.

Please refer to the following link for related details.

Hello,

We need to use the RSSI value of BLE signals sent from the Smartphone to estimate the distance between the Smartphone and the Reader Device. Unfortunately in some cases with the same environment we got higher value in a higher distance. We are actually using Samsung 8. Besides the influence of fading and interferance, our assumption is that the controller in the BLE chipset integrated BCM4361 is changing the Tx Power Level.

Is the Controller of the BLE chipset indeed changing this value? What are the conditions? 

Thank you for your support,

Hi,

I use CYBT-343026-01 module with ezserial_343026-CYBT_343026_EVAL-rom-ram-Wiced-release FW. I tested it via uart send API command to it. But find two problems.

1. Command's response is not always back.

For example, I send many times of "/QFV\r\n", but the reponse is not back 100%. And I check the uart data via oscilloscope of the BT module RX, recieve completely OK, but module TX no data. I don't know why? Need I set ".CYSPPSP,E=0"? Or do something for CYSPP pin?Below is the screenshot for RX data.

2. If I send "/QFV" and "GAD" many times, commans no response(as 1 descriped). Then "GAD" been sent again, but "/QFV" response come back. It is strange.

Hi,

I want to custome uart protocol to modify advertisement data when uart recieve "SAD,D=0102" command.

But once I set "SAD,D=0102" command from uart with new FW, modeule restart. I don't know where is the problem.

I use CYBT-343026-01 EVAL board to do the testing.

Please check my code.

Hi,

I get CYBT-343026-01 module. I want to download new image to CYBT343026-01 module. I have tested CYBT343026-01 EVAL board and use WICED-Studio tool to download new image to EVAL board, it is OK. But I don't know how to download new image to CYBT343026-01 module.

1. Now I use uart line to connect RX, TX and GND to module respectively.

2. Use WICED-Studio's "Make Target" which is "iBeacon-CYBT_343026_EVAL UART=COM3 download" to do dowloanding.(PC port is COM3)

But it is not OK.

I doubt maybe "iBeacon-CYBT_343026_EVAL UART=COM3 download" is wrong?

Hi,

I want to use ezserial_343026-CYBT_343026_EVAL-rom-ram-Wiced-release FW in CYBT-343026-01.  Is the hardware design OK for this officail release?

UART3_TX shoud be GPIO3 or P4/p24? Could you give me a confirmation?

Is  CYPRESS planning to release a +10 dBm EIRP (or more)  BT 5 module implementing Coded PHY modulation, in the near future? Thanks

Hi,

We are using the 20719 board and we are wondering if it is possible to have an audio input from a bluetooth device and have that audio data transferred to a computer. I saw that Hands-free profile and A2DP sink are not supported, but we still want to know if there is a way to do that.

Thanks!
