Studio Bluetooth Forum Discussions
Hi ,
We are using CYW920721B2EVK-02 as a bluetooth device. We want to enter in to shutdown mode when there is no activity.
In callback sleep handle we are giving WICED_SLEEP_ALLOWED_WITH_SHUTDOWN. But from the traces we see it is not going to shutdown mode.
Can anyone help us how to enter shut down mode .
Thanks for your help in advance.
Thanks & Regards,
Krishna.
Show LessHello,
I found the following description in the datasheet of CYBT-3330xx-02.
Is the MIC-JAPAN regulation for CYBT-333032-02 approved for the antenna listed in Table 6?
Only FCC is listed here, but can I use without additional application and testing for MIC-JAPAN regulation ?

I am using CYBT-343026-01. I have tested 2-3 randomly from 400 devices. I have written a new code. to test sleep functionality.
I believe wiced_sleep_config( WICED_TRUE, NULL, NULL ) PMU will determine when it should sleep and wake up. In short, it will sleep whenever it will get the time, and there no user control over it.
Code:
wiced_sleep_config( WICED_TRUE, NULL, NULL );
There is 1 timer (execute at every 1 second) which keeps the printing current count++. Apart from this, there is nothing written. and I can see current consumption is less than 1 mA for 1st 20-30 minutes. but some time (approximately after 20-30 minutes) current suddenly increases to 8mA and when I am trying to forcefully execute wiced_sleep_config( WICED_TRUE, NULL, NULL ); it is not working. I have to hard reset every time to make it consume low. Why So?
I have also tried to use wiced_allow_sleep(TRUE);
First of all, it should not take this much high current when I am doing nothing.
Why wiced_sleep_config( WICED_TRUE, NULL, NULL ) is stopping its working after some time?

Show LessHi,
We are using CYW920721B2EVK for our bluetooth application.
In this device will there be any difference in these sleep modes 1) WICED_SLEEP_MODE_NO_TRANSPORT
2) WICED_SLEEP_MODE_TRANSPORT

I am doing repeated BLE scan/stop scan and after around 10 times I will stop getting the sleep callback. I am not doing any more BLE actions at this time. What is preventing this from happening? This is my sleep config:
sleep_config.sleep_mode = WICED_SLEEP_MODE_NO_TRANSPORT;
sleep_config.device_wake_gpio_num = WICED_P07;
sleep_config.device_wake_mode = WICED_SLEEP_WAKE_ACTIVE_HIGH;
sleep_config.device_wake_source = WICED_SLEEP_WAKE_SOURCE_GPIO;
sleep_config.host_wake_mode = WICED_SLEEP_WAKE_ACTIVE_HIGH;
This is my sleep handler. I check 2 pins are low before I allow sleep:
uint32_t sleep_handler(wiced_sleep_poll_type_t type )
{
uint32_t ret = WICED_SLEEP_NOT_ALLOWED;
switch(type)
{
case WICED_SLEEP_POLL_SLEEP_PERMISSION:
if ((wiced_hal_gpio_get_pin_input_status(WICED_P07) == 0) &&
(wiced_hal_gpio_get_pin_input_status(WICED_P08) == 0))
{
ret = WICED_SLEEP_ALLOWED_WITHOUT_SHUTDOWN;
}
break;
case WICED_SLEEP_POLL_TIME_TO_SLEEP:
if ((wiced_hal_gpio_get_pin_input_status(WICED_P07) == 0) &&
(wiced_hal_gpio_get_pin_input_status(WICED_P08) == 0))
{
ret = WICED_SLEEP_MAX_TIME_TO_SLEEP;
}
else
ret = 0;
break;
}
return ret;
}
If I don't get the sleep callback, does it mean it is not going to sleep anymore? I still get GPIO interrupts but no sleep callback after processing is done.
Show LessHi,
I have testing HID Device . But, i can not connected to bluetooth of my notebook on firstly connection.
its connection is down after 30 second when it connection is established.
in case of my cellphone, connection is working normally without cut off.
i have used default example hid source in SDK 6.2, trying connection in ClientControl.exe.
please, anybody help me.
thanks.
Show LessI've been looking through these forums for a suitable bluetooth module:
1. I2S audio output (48kHz/16 bit minimum)
2. SPP communications
3. Use UART or similar to change bluetooth name, activate pairing, etc.
I'd like to avoid having to learn the details of a new development platform - is there a module available that does this? Or sample software that comes very close for modules such as the CYBT-343026-01?
Thanks!
Show LessI am using CYBT-343026-01. I have used find me example and added wiced_sleep_config( WICED_TRUE, NULL, NULL ); API to make sure it should consume minimum current. And its average current consumption is 320mAh. I have given firmware in production for 400 nos. after testing 2-4 days. But its almost 1 month, now the problem is beacons whos battery is still sufficient (2.9-3.0v) but it has stopped broadcasting. We need to reset by replug-in to make it broadcast.
Is this because we have used wiced_sleep_config( WICED_TRUE, NULL, NULL ); API?

Show LessHi, we are using CYW20706+Wiced6.4 for an important project, after days of pressure test, we found a tricky problem:
In a fast booting senario (power on/off hundreds times ), part of SS section (2~3KBytes from address 0x0000) might be written to 0 , so the chip will boot to HCI mode as it think the SPI flash is invalid, although the application area (start from 0x4000) is still there.
This is a huge risk for us as when SS corrupted , the chip can not work at all !
Can anyone help me ?
HELP!
THANKS!

Hi
How is the situation regarding EN 300 328 V2.2.2 support of CYBT-343026-01?
If so, the customer wants the evidence (PDF, Web site, etc.).
Could you provide it for them?
Thanks
Yang
