使用UART配置BLE

你好呀，

我正在尝试使用UART与BLE并行。出于我的项目目的，无附庸术和DSP不适用，不可能做出足够的修改。因此，我决定在与BLE_APP_PERITIELALAL示例中使用示例项目中演示的UART功能。

据说，在导入所需的一些库之后并在BLE示例中启用DMA模式;我跟着这个powccess：

• 订阅ADC值1时，我想每5秒开始读取数据。

void user_svc1_adc_val_1_cfg_ind_handler（ke_msg_id_t const msgs，struct custs1_val_write_ind const * param，ke_task_id_t const dest_id，ke_task_id_t const src_id）{//在中央订阅时生成指示（param-> value [0]）{printf_string（UART2，“用户已经订阅了ADC特征！\ 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); }

在阻止收到的情况下，我不使用计时器。但是，如果我不立即输入数据，则计划崩溃“而（！Uart_data_ready_getf（Uart_id））;”命令in.“UART_READ_BYTE（）”。

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

• 如果我坚持原始代码和使用“虽然（！recept_uart_finished）;”由于代码相同的代码，程序管理程序将崩溃。

我想知道，我能做什么来解决这些问题？是否有一些我没有为UART配置的东西？有一个更好的方法吗？（除了使用无附带或DSP外，因为它们看起来非常难以修改）
