用UART配置BLE

你好，

我正在尝试将UART与BLE并行使用。就我的项目而言，无代码和DSP不适用，不可能进行充分的修改。因此，我决定将示例项目中演示的UART功能与ble\u app\u外围示例结合使用。

也就是说，在导入一些所需的库并在ble示例中启用dma模式之后，我遵循以下过程：

• 订阅adc值1后，我希望每5秒读取一次数据。

void user \u svc1 \u adc \u val \u 1 \u cfg \u ind \u handler（ke \u msg \u id \u t const msgid，struct custs1 \u val \u write \u ind const*param，ke \u task \u id \u const dest \u id，ke \u task \u id \u const src \u id）{//如果（param->value[0]）{printf u string（UART2），“用户已订阅adc特征，则在中央订阅时生成指示！”！\n\r“；SendRecSM_op（）；}}

• I tried using different interupt modes:

ke_msg_id_t timer_used_SendRec_SM __SECTION_ZERO(“retention_mem_area0"); //@RETENTION MEMORY uart_t * uart = UART2; const int READ_CHAR_COUNT = 5; static char buffer_BLE[READ_CHAR_COUNT + 1]; volatile bool uart_receive_finished = false; volatile uint16_t data_received_cnt = 0; //Function Definitions void SendRecSM_op() { //blocking_receive_uart(); intr_receive_uart(); //dma_receive_uart(); app_easy_timer(500,uart_chk_buffer_cb); } static void uart_receive_cb(uint16_t length){ data_received_cnt = length; uart_receive_finished = true; } void dma_receive_uart(){ uart_receive_finished = false; data_received_cnt = 0; uart_register_rx_cb(uart, uart_receive_cb); //Time to ask for data! uart_receive(uart, (uint8_t *)buffer_BLE, READ_CHAR_COUNT, UART_OP_DMA); } void uart_chk_buffer_cb() { arch_printf("\n\rChecking the buffer!\n\r"); if (uart_receive_finished){ buffer_BLE[READ_CHAR_COUNT] = 0; // make it a null terminated string printf_string(uart,buffer_BLE); } } void intr_receive_uart(){ uart_receive_finished = false; data_received_cnt = 0; uart_register_rx_cb(uart, uart_receive_cb); //Time to ask for data! arch_printf("UART is in Interrupt mode!\n\r"); arch_printf("Please input the data!"); uart_receive(uart, (uint8_t *)buffer_BLE, READ_CHAR_COUNT, UART_OP_INTR); } void blocking_receive_uart(){ printf_string(uart,"UART is in Blocking mode!\n\r"); printf_string(uart,"Please input the data!"); uart_receive(uart, (uint8_t *)buffer_BLE, READ_CHAR_COUNT, UART_OP_BLOCKING); buffer_BLE[READ_CHAR_COUNT] = 0; // make it a null terminated string printf_string(uart,buffer_BLE); }

在阻止接收的情况下，我没有使用计时器。但是，如果我不立即输入数据，程序会因为“而（！uart_data_ready_getf（uart_id））；“命令输入“uart读取字节（）”.

In case of interrupted receives, I use the said timer. However, the program runs only once. In other words, it only prints“正在检查缓冲区！”and regardless of what I would do, everything would freeze.

• 如果我坚持使用原始代码“而（！接收（已完成）；“程序将由于同一行代码而崩溃。

我想知道，我能做些什么来解决这些问题？有没有我没有为UART配置的东西？有没有更好的办法？（除了使用无代码或DSP之外，因为它们似乎很难修改）
