I am using a CySmart BLE 4.2 dongle to detect and connect to my CVBT-42302802 module. I am using BTSpy.exe and ClientControl.exe with the appropriate trace messaging in my WICED application configured for WICED_ROUTE_DEBUG_TO_WICED_UART. When the CySmart dongle requests pairing, I get the following messages at the end of the pairing process.

What is command 0x204e? I can't seem to find any documentation on this command.
Show Less20706ble功能验证中,广播的时候可以进入低功耗,此时功耗为0.4ma,连接上的时候进不了低功耗了,此时功耗为4ma,
客户这边测试情况是加入进入低功耗wiced_sleep_config(WICED_TRUE,WICED_WAKE_GPIO_ACTIVE_LOW,WICED_WAKE_GPIO_ACTIVE_LOW);广播功耗由3ma降到了0.3ma,
而连接状态时功耗几乎没有任何变化,这个是什么原因?
Show LessHi
I'm having an issue with Bluetooth transmission where my program is erroring out after the 20th iteration. I found out the setting max_attr_len in the file wiced_app_cfg.c.
The default value is 20. when changing this setting, there is no change in the behavior of my code. on the 20th iteration the system is throwing WICED_BT_GATT_CONGESTED once followed by WICED_BT_GATT_INTERNAL_ERROR for the rest of the loop.
I noticed that in the comment section there is a reference to gki_cfg which I am not able to locate in any of the files.
Has anyone had to deal with this issue before?
Thank you for your time and assistance.

I have a problem with my code where it gives me this event BTM_BLE_CONNECTION_PARAM_UPDATE and this is when I use the rtcClock1.reg32map.rtc32[2];
can anyone give me a hint as to why and what should I do?
this is part of my code:
int i = 4000;
int f = 1;
int dt = 500;
volatile uint16_t voltage_val_adc_in_mv[2*(i+1)];
volatile uint16_t Time[2*(i+1)]; //initializing the time here
volatile uint16_t vddio_mv = 0;
volatile uint16_t temperature;
vddio_mv = wiced_hal_adc_read_voltage(ADC_INPUT_VDDIO); /* Input channel to measure Reference voltage for Voltage divider calculation for Thermistor */
WICED_BT_TRACE("\r\nVDDIO_mV\t%d \r\n", vddio_mv);
// Initialize Time
tRTC_REAL_TIME_CLOCK rtcClock1;
rtcConfig.oscillatorFrequencykHz = 32;
rtc_init();
void wiced_hal_gpio_disable_all_inputs();
wiced_hal_adc_set_input_range(ADC_RANGE_0_3P6V);
for (int j=0 ; j <= i ; j++)
{
voltage_val_adc_in_mv
rtc_getRTCRawClock(&rtcClock1);
Time
}
Show LessHello,
I am looking at the WICED 6.2.1 [20706-A2_Bluetooth] apps/snip/bt/hci_handsfree.
I have the following questions:
For example, if the FW that has not made any changes to this snip is downloaded to CYW920706WCDEVAL, does it work with only the PCM pin and codec IC connected?
When I look at the code, it looks like there is no assignment to the PCM pin.
In order to build only handsfree profile, please tell me about that method.
Also, what kind of CODEC IC is recommended?
Best regards,
Kenji Takahashi
Show LessHi All.
I am testing a CYBT-483039-02 module and something brings my attention. Does this module (as is the case with BLE modules from other manufacturers I´ve tested) need a host PCB ground plane to achieve the expected Tx power? When I review the available antenna design documentation, all I find is recommended clearance space details but nothing about the need of a ground plane to bust the RF transmitted power. Is maybe this antenna chip it includes different from traditional trace antenna solutions in which a ground plane on the host PCB is mandatory? Thanks

How do I clear the BLE stack during transfer loops?
Hello, I cannot find any sample code for the a2dp source code from wiced stack. Can anybody point me to any sample/demo source code?
thanks in advance,
Show LessHi Cypress:
How to set the pairing mode of CYW20706 to require PIN CODE?
set p_event_data->pairing_io_capabilities_br_edr_request.auth_req.
But it didn't work
Show Less硬件问题1、
master only是指这个脚只能做master? 请帮忙找4个能做SPI slave的管脚给到我们。
硬件问题2、
89820 RF能不能采用之前如下2070X的方案,即用LFB212G45CG2D013 即可。
硬件问题3
需要帮忙看一下关于程序下载和在线debug的问题!
软件问题1
1:89820demo板,2:需要烧入的蓝牙协议栈demo工程(要源码的)(还有如何烧入), 3:手机端(安卓程序)简单的测试demo(要源码的)
