CC2541 UART發送問題

在event 中用HalUARTWrite(HAL_UART_PORT_0,"a",1);發送後, cc2541 的電流保持8.xmA.如果沒有這句,能自動進入pm2和pm3.

program 為keyfobdemo.後加_hal_uart_dma.c.

defined如下:

INT_HEAP_LEN=3000
HALNODEBUG
OSAL_CBTIMER_NUM_TASKS=1
HAL_AES_DMA=TRUE
POWER_SAVING
xPLUS_BROADCASTER
HAL_LCD=FALSE
HAL_LED=TRUE
CC2540_MINIDK
ACC_BMA250
DC_DC_P0_7
HAL_UART=TRUE
HAL_DMA=TRUE

uartConfig如下:

halUARTCfg_t uartConfig;
uartConfig.configured = TRUE;
uartConfig.baudRate = HAL_UART_BR_9600;
uartConfig.flowControl = HAL_UART_FLOW_OFF;
uartConfig.flowControlThreshold = 48;
uartConfig.idleTimeout = 6;
uartConfig.rx.maxBufSize = 128;
uartConfig.tx.maxBufSize = 128;
uartConfig.intEnable = TRUE;
// uartConfig.rxChRvdTime =
uartConfig.callBackFunc = NULL;

HalUARTOpen (HAL_UART_PORT_0, &uartConfig)

另將CTS 腳踫一下GND,CC2541 就可以進入pm3.

請問如何將cc2541 在event 中發送uart 通過dma後, 又可以自動進入pm2或pm3?

使用串口前，调用osal_pwrmgr_device( PWRMGR_ALWAYS_ON );

使用完毕后，调用osal_pwrmgr_device( PWRMGR_BATTERY ); 恢复省电模式
