Bluetooth SDK Forum Discussions

I am using the EZ-Serial Host API Protocol Library with the CYBT-343026-01.

App: 1.2.29 build 29
Stack: 5.2.0 build 22
Protocol: 1.3
HW: CYBT-343026-01

I have found other posts asking about this same issue but none that lead to a solution.

Sometimes the module shows up (broadcasts) as type 2 (BLE) and sometimes as type 3 (Dual Mode). When it shows up as dual mode, I can connect with BT Classic but when it shows up as BLE, I cannot connect in classic mode.

I only require BT Classic. Is there a way to setup for BR/EDR only or force Dual Mode every time? Once connected, I am only using SPP.

Thank you.

Hello,

I would like to use Quad SPI Master with CYBT-413061-02 (CYW20721).

I plan to use the Modus Tool Box / Bluetooth SDK.

However, in the 20719/20721 Hardware Driver's SPI peripheral API, I can only find the Standard SPI setting.

I recognize that the 20719/20721 supports Quad SPI.

Why isn't there an API?

Thanks

Hi

It is about Bluetooth SDK. What I got at my disposal is Simplicity Studio 4 with a wireless starter kit if that even matters. What I want to accomplish is to gain all information available from another Bluetooth device that I don’t have physical access to by using wireless preferably Bluetooth. I have logs from it that I gained from Wireshark using hcitools lescan. (It is using a random mac-address that changes every five ten minutes, broadcasting two different advertisement packets one after another.) It is most certainly connected to a microcontroller

I am having trouble with this since I am a complete beginner. Need a complete how-to guide.

Can you point me to an application note or some other documentation that provides recommendations on performing a Factory Calibration routine for the CYW20719B2 ADC?  We are using the ADC in Static mode (to monitor Battery voltage), but the observed unit-to-unit variation seems to indicate that we need to add a calibration routine.  

Apart from recommendations on how to best perform the calibration (number and type of measurements),  we're also looking for recommendations for how to store the Cal values (I suppose in NVRAM) and retrieve them during normal operation.

Dear Sir,

请问20719B2 如何读取TX FIFO状态？

另外: wiced_hal_puart_synchronous_write和wiced_hal_puart_write都是阻塞发送吗？

Best Regards,

I am evaluating the CYW20706 and the AIROC solutions as a replacement for our existing IoT Bluetooth functionality. It is essential for the operation of our system that we have access to the Bluetooth clock. We do that currently using the HCI command HCI_READ_CLOCK because we have a 2 chip solution with an HCI bus in between. I do not see any API support for this functionality in AIROC and wondered if you had any advice or suggestions.

We are using the HCI UART of the CYW20719B2 chip in Raw Mode.   We have the communication working , but have noticed that there is a delay of ~ 50ms from when data is placed on the CYW20719's RX Pin to when the RX Interrupt is registered with the Application-Level code (i.e. the callback handler registered at: wiced_transport_cfg_t.p_data_handler ).  This amount of delay seems excessive and is impacting the responsiveness of our system.

What controls the delay from the Hardware Block to the Application Level, ... and can this delay be reduced?

These are our configurations for the HCI UART:

wiced_transport_init(&(wiced_transport_cfg_t) {
.type = WICED_TRANSPORT_UART,
.cfg = {
.uart_cfg = {
.mode = WICED_TRANSPORT_UART_RAW_MODE,
.baud_rate = M_HCI_UART_BAUD_RATE (230400),
},
},
.rx_buff_pool_cfg = {
.buffer_size = RX_BUFFER_SIZE (2000),
.buffer_count = RX_BUFFER_COUNT (2)
},
.p_data_handler = m_hci_uart_rx_handler__,
.p_status_handler = m_hci_uart_status_handler__,
.p_tx_complete_cback = m_hci_uart_tx_complete__,
});
