No tos_hal_uart_read() function in /net/at/src/tos_at.c about tobudos HOT 4 CLOSED

Thanks for your question. We use tos_at_uart_input_byte() to read char data in uart interrupt，this function will push data into fifo. So you can do it like this https://github.com/Tencent/TencentOS-tiny/blob/master/board/TencentOS_tiny_EVB_MX_Plus/BSP/Src/stm32l4xx_it_module.c
#include "tos_at.h"
...

/* USER CODE BEGIN 1 */
void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart)
{
extern uint8_t data;
if (huart->Instance == LPUART1) {
HAL_UART_Receive_IT(&hlpuart1, &data, 1);
tos_at_uart_input_byte(data);
}
}

Thank you so much for your guidance! I have modified my program and it can work properly now.
By the way, I noticed that if I use the configuration in the example above, I have to call HAL_UART_Receive_IT() once after MX_USARTx_UART_Init(), perhaps in tos_hal_uart_init() in /kernel/hal/tos_hal_uart.c. (I am using stm32f103 MCU)

Yes we must call HAL_UART_Receive_IT() once after MX_USARTx_UART_Init()， This is determined by the use of the STM32 HAL library. We will not merge your PR, because we will update the code of the AT framework in the next month to improve the overall performance.

Well noticed with thanks~
