Studio Bluetooth Forum Discussions

Hi, I'm developing CYW20706 Bluetooth chip.

I have some questions.

The CYW20706 is connected to android smartphone.

There are installed VoIP applications such as Skype, Whatsapp and Viber in android smartphone. (except iPhone)

I would like to receive incoming call via VoIP using CYW20706.

When a call is incoming via VoIP, the call state of CYW20706 is displayed outgoing call.

I can't understand this situation.

The incoming call is good in general call situation.

But the incoming call via VoIP is problem.

When the call via VoIP using CYW20706 or general Bluetooth chip is incoming, Why does the outgoing call displayed?

How do I change the outgoing call status to incoming call?

Can I change the call status using AT command?

I attach the log about this situation.

I am using handsfree application from the WICED SDK. As soon the application starts running, there are 35 bytes of HCI event data sent of the HCI UART. How to avoid these bytes being sent ?

Hi yssu​

Per your comments here: programming CYW20706​

If I download my application code to external flash, how do I protect my code?

Regards

     Hi：

          Problem one：

          After version 5.0，There is no "wiced_hal_lpm.h" file,Enter and exit the sleep mode of the original has been unable to achieve,Now the 6 set sleep mode of API is where?

          Problem two：

          in addition,Set the sleep in "mesh_application.c" this C file,"#define _DEB_SLEEP ", but open compiler error.why?

                              thanks~

Following screenshot：

I want to use a CYW20706 soc for a embedded Bluetooth application and could not find information how to flash my compiled program to the chips memory.

Do i need a extra programmer device, like for atmels atmega, or just USB to uart transmitter and the program is transmitted via the uart interface ? 

I found a .zip file for cybt-343026-eval but I cannot find the directory mentioned in studio 5.2 on linux. I looked in WICED-5.2, Cypress, /usr/share/applications and /opt/cypress directories but I cannot find the Platforms directory anywhere.

Also I have a more fundamental question: what code comes loaded on the cybt-343026-eval bluetooth module? HCI? EZ-serial? Nothing? I plugged in the board and it created the /dev/ttyACM0 and /dev/ttyACM1 uart devices, but I've tried sending lots of stuff to them and the do not respond with even a single byte. I didn't change any of the default switches or jumpers on the board. I do see one red light blink on the board when I send lots of charaters. I'm using 115200 bps.

How can I load EZ-serial and HCI or whatever code I want without having to use the studio software? Also, where do I get the .hex (or whatever) firmware images to download. I want to do this all in linux.

Finally, should I be using smart instead of studio? and how do I get studio to probe the board to validate that I have everything working?
