Studio Bluetooth Forum Discussions
I am not able to find the I2S library. I was expecting to find an I2S driver in HAL folder ... but it isn't. Checking the files the closest one (to I2S) is "wiced_hal_pcm.h"
Can you tell me where to find the I2S drivers/API in WICED for the CYW20719?
Show LessHello,
I am working on SPP example from the Wiced studio. This example is responsible to receive data and it sends the huge amount of data on the interrupt button.
But I would like to send the data as user input not as interrupt button, I tired to change the code and did some experiments but still I am not able to achieve it.
Could anyone please help me with this?
Thanks in advance.
Show LessI am in a senior design team at Mississippi State University. We are creating a heart rate monitor that can be used on the ankle. We have used the dev board up to this point but we are now in the second phase of the project in which we need to place the MCU on other needed components onto a PCB. We need a wiring schematic for the dev board so that we can see what components are needed and how that should be configured. We need the schematic as soon as possible so that we can continue our project.
Show LessCYBT-413034-02, I want to use the module. I got six. Is it possible to transfer sound with this? How can I do that ? Can I get the circuit diagram and software support?
Show LessHi,
I assume that the CYBT-343026 module has a ready made image embedded inside the module. If I connect this Bluetooth Module to my host MCU through a UART, I can directly use the Wiced HCI API to control the module. it means that I only need to develop an application on the host MCU side. Is it right?
I want the module plays central and peripheral role at the same time, BLE/Classic at the same time.
Thanks in advance.
Show LessHello,
I want to use the CYBT-333032-02 with linux via HCI UART inteface.Do i need to install a driver or linux will autodetect the module ?
I found that the CySmart is only supported on windows pc and also the ModusToolbox™ Software Environment is available on windows and linux but doesn't support the CYBT-333032-02.
Many thanks for help
Show LessHello,
Testing A2DP source functionality using 'watch' demo app and Client control on PC, using CYBT-343026.
In our actual application, we will be streaming audio data over I2S bus.
While using serial HCI uart to communicate with host microcontroller.
We would like to know, at 115200 baud rate, do we need to implement Hardware handshake using RTS/CTS lines?
Can we enter the HCI mode on CYBT-343016, (as mentioned in blog by Owen_Z in https://community.cypress.com/community/wiced-studio-blueooth/wiced-studio-bluetooth-forums/blog/2019/06/27/run-cyw20706-in-hci-mode) by just pulling high, CTS pin at reset then maintaining it low, and then simply leaving CTS, RTS line in fixed conditions. Host microcontroller UART will communicate without hardware handshake, while maintaining a serial buffer in it's firmware.
What could be the perceived issues using above approach.
Any insight will be appreciated.
Best Regards,
Vinay
Show LessHello,
I am using a CYW20719 MCU in a custom design, most of my design is based on the CYW920719Q40EVB reference design. I have attached my schematic below. I am programming the device using a 3.3V FTDI USB-to-UART cable, which I have successfully done before on the development kit attaching it to the serial jumpers.
First, I have probed each test point pictured and verified that they behave as expected. The internal buck converter and voltage regulator is operating correctly, and the reset circuit operates as expected. The RESET and RECOVER buttons (not pictured) connect the RST_N or BT_UART_CTS nets, respectively, to ground. After powering up the device, I have verified with an oscilloscope that the 24.000 MHz oscillator waveform is good. The 32.768 kHz oscillator does not oscillate in the default (unprogrammed) state, it appears.
This is the antenna circuit being used, utilizing the Johanson Technologies 2450AT42B100E, which I have used successfully before with the CYW20719, following all of the appropriate design guidelines.
My problem is:
The device will not program, I have swapped out several components including the CYW20719 itself, on each iteration, all operating parameters seem fine (CBUCK voltage, oscillators, etc.). One strange behavior (which I have not verified if the development kit also behaves this way), is that the 24.000 MHz waveform nearly doubles in amplitude and looks distorted (but is still on frequency and roughly sinusoidal), only when the device is put into RECOVER mode, but will return to normal (1.0 Vpk-pk) when reset into non-RECOVER mode. I had a device program once randomly (without changing anything from before when it would not program) and then never again. I have since swapped out the chip and have not been able to see any successful programming again. Are there any obvious errors or concerns with my design? Or any tips or things I should check for?
Thanks,
Show LessWhen the BLE device is advertising, it can be found normally by Android and iOS phones with apps such as CySmart and Lightblue. However, when I use the Bluetooth on the phone without these apps, only Android devices discover the device; iOS devices do not. How do I make the BLE device discoverable by iOS devices?
