ModusToolbox Bluetooth SDK

大佬们好！

我在使用CYW 20706模块调试AVRCP协议时（IDE ModusToolbox, bt_sdk 2.5），调用avrc_app_pass_through(uint16_t handle, uint8_t op_id,uint8_t state)函数控制音量，函数反馈“WICED_SUCCESS”，但手机端音量无变化，更换多个手机测试无果。调试过程AVRCP协议连接正常，上/下曲、播放/暂停等功能都正常。

手机端关键LOG：

D Avrcp_ext: Avrcp current play state: 2 isMusicActive: false A2dp state: 11 Cached passthrough command: 0

W Avrcp_ext: Passthrough non-media key 65 (code 24) state 0

D Avrcp_ext: cached passthrough: 0current passthrough: 24

W MediaSessionService: Attempted to dispatch null or non-media key event.

V Avrcp_ext: Exit handleMessage

我查看了Android的KEYCODE定义，KeyEvent.KEYCODE_VOLUME_UP = 24.

请问导致这个问题的原因可能有那些？是否存在解决的方法？

Hi,

I am using the CYW20819EVB-02 board and I am trying to enable notifications with web ble 

https://googlechrome.github.io/samples/web-bluetooth/notifications.html

https://googlechrome.github.io/samples/web-bluetooth/read-characteristic-value-changed.html

I keep getting errors, even though enabling notifications work fine with the cypress app on mobile.

Is there something I am missing? (do i need to respond to the start notification?) 

Any help would be greatly appreciated

Thanks in advance!

I'm using a CY8CPROTO-063-BLE board. When I try to initialize the BLE ECO clock, Cy_BLE_EcoConfigure() returns CY_BLE_ECO_HARDWARE_ERROR. The proximate cause is a time-out waiting for the  BLE_BLESS_MT_STATUS.BLESS_STATE bit to be set, at line 409 in cy_ble_clk.c.

I have previously had BLE working in both Central Device and Peripheral roles, on two different copies of the board, and both boards now display the same behavior, so it's unlikely actually to be a hardware error. It's almost certainly a configuration problem, but I have no idea where to start looking.

    /* Wait for BLESS in ACTIVE state */
    while(((BLE_BLESS_MT_STATUS & BLE_BLESS_MT_STATUS_BLESS_STATE_Msk) == 0U) && (timeout > 0U))
    {
        timeout--;
        Cy_SysLib_DelayUs(CY_BLE_DELAY_TIME);
    }
    if(timeout == 0U)
    {
        status = CY_BLE_ECO_HARDWARE_ERROR;
    }

Any suggestions would be appreciated.

Thanks,

I have been facing the problem that spp_scb.flow_control_on never revert back to FALSE on high-load operation.
It occurs in rare cases when receiving and transmitting are performed at same time.
In this case I cannot transmits data any more.

I'd like to get the information about how to fix it or how to poll flow status.

spp_scb.flow_control_on is set in the following callback.
Is there a possibility that the callback vanishes into nothing?

void spp_port_event_cback(wiced_bt_rfcomm_port_event_t event, uint16_t handle){

if(event & PORT_EV_RXCHAR){
<*snip*>
}
if(event & PORT_EV_FC){
spp_scb.flow_control_on = !(event & PORT_EV_FCS) ? WICED_TRUE : WICED_FALSE;
}
if(event & PORT_EV_TXEMPTY){
spp_scb.flow_control_on = WICED_FALSE;
}

spp_scb.event_error = (event & PORT_EV_ERR) ? 1 : 0;

return;
}

Can someone modify the Handsfree or headset snip in Modus 2.2 to demonstrate PCM out and PCM in for the 353027-EVAL board?

I've been trying but unsuccessfully to get this to work.

Hello guys,

I have a custom board with cyw20719b2, with a build setup using modus toolboox 2.1 and wiced bt sdk v2.7.1 fdb3982. As this is a custom board for embedded environment, the host is not really connected.

I have sleep configuration like this:

wiced_sleep_configure(
    &(wiced_sleep_config_t) {
        .sleep_mode                   = WICED_SLEEP_MODE_TRANSPORT,
        .device_wake_gpio_num         = WICED_P28,
        .device_wake_mode             = WICED_SLEEP_WAKE_ACTIVE_HIGH,
        .device_wake_source           = WICED_SLEEP_WAKE_SOURCE_GPIO,
        .host_wake_mode               = WICED_SLEEP_WAKE_ACTIVE_HIGH,
        .sleep_permit_handler         = m_shutdown_handler,
    }
);

Here in the sleep configuration WICED_P28 is connected to interrupt pin coming from PMIC (Which gives push button / charger connect etc interrupts coming from PMIC).

So my problem is that, I also need the WICED_P28 pin for GPIO interrupt to handle various interrupts coming from PMIC.

When I tried to configure WICED_P28 for both (wiced_sleep_configure() & wiced_hal_gpio_register_pin_for_interrupt()), the gpio interrupt never gets called.

My question is, if it is possible to use same gpio pin for wiced_sleep_configure() & wiced_hal_gpio_register_pin_for_interrupt() ?

Thanks,
