On_ble_powered（）回调

我们有一个应用程序，主机MCU每〜6.3秒通过SPI接口向DA14585发送4K页数据。然后DA14585通过通知将该数据继承到无线电。页面之间，我们进入扩展睡眠模式，主MCU使用唤醒定时器唤醒DA14585。通过DMA接收SPI数据，DMA完成的IRQ处理程序将自定义消息发布到内核以启动内核并返回延长睡眠。除了如下所示，所有这些似乎都良好：

It appears that the kernel message is only getting through if the BLE core is active when the DMA IRQ handler (actually callback) executes and the message gets sent. Reading section 7.1.2 of the SW Platform Reference suggests that messages need to be synced with the BLE core. I am inferring that this is the purpose of the on_ble_powered() callback. I modified the code to set a flag in the DMA IRQ handler, then check the flag in an on_ble_powered() callback function. If the flag is set, I send the message to initiate the notifications/characteristic value updates and clear the flag.

但是，通过该代码到位，DA14585无法甚至不再宣传。为什么添加一个on_ble_powered（）回调中断代码？当异步事件需要发送消息时，是否有更好的方法“与BLE核心同步”？

以下是相关功能：

DMA完成的回调函数：
静态void epilog_spi_dma_done（void * userdata，uint16_t len）
{
/* Prep data for Bluetooth */
EEG_RT.DATA = RTEEG_BUFFER;
memcpy（＆eeg_rt.pageaddr，spi.parmbuf，btspi_parm_len）;

/ *重置SPI状态* /
spi_reset_state（）;
spi_int_bit_clear（）;
nvic_clearpendingirq（spi_irqn）;
spi_enable_irq（）;

RTPARTEADY = TRUE;
// epilog_spi_send_page_done_msg（＆eeg_rt，rteeg_buffer + eeg_page_size）;
}

on_ble_powered（）回调：
ARCH_MAIN_LOOP_CALLBACK_RET_T SEND_PAGE_ON_BLE_POWERED（void）
{
if（rtpageready）{
epilog_spi_send_page_done_msg（＆eeg_rt，rteeg_buffer + eeg_page_size）;
rtpArteady = false;
}

返回keep_powered;
}

页面发送功能：
静态void epilog_spi_send_page_done_msg（struct eegdata * eeg，uint8_t * evt）
{
struct msg_page_done * msg_param;

msg_param = KE_MSG_ALLOC(APPMSG_PAGE_RECEIVED, TASK_APP, TASK_APP,
msg_page_done）;

msg_param-> eeg = eeg;
msg_param-> evt = evt;

KE_MSG_SEND（MSG_PARAM）;
}

最后，从user_catch_rest_hndl（）函数剪辑以处理appmsg_page_received msg：
案例appmsg_page_received：
{
struct msg_page_done *msg_param = (struct msg_page_done *)param;
uint8_t state = ke_state_get（task_app）;

if（state == app_connected）{
eegdata_start_notify（msg_param-> eeg）;
EEGEVENT_START_NOTIFY（MSG_PARAM-> EEG，MSG_PARAM-> EVT）;
}

/ *重新启用睡眠模式* /
app_enable_wakeup（）;/ *设置wkupct * /
ARCH_SET_EXTENDED_SLEEP（FALSE）;

}
休息;
