does UART will stop working while receiving remote Msg （or Under in PM2）

The Seven

Hi all，

i initial a UART by mysel （do not using MT） like below ：

ps:HAL_UART_DMA == 1

void SerialInit(void)
{
  halUARTCfg_t uartconfig;
  uartconfig.configured = TRUE;
  uartconfig.baudRate = FS_UART_DEFAULT_BAUDRATE;//57600
  uartconfig.flowControl = FALSE;

  uartconfig.flowControlThreshold = 5;
  uartconfig.rx.maxBufSize        = 128;
  uartconfig.tx.maxBufSize        = 128;
  uartconfig.idleTimeout          = 6;
  uartconfig.intEnable            = TRUE;
  
  uartconfig.callBackFunc =FS_UartProcessZToolData;//SerialCallBackFunc;   
  
  HalUARTOpen(0,&uartconfig);
}

when the device do not joined the network， the UART was worked. there is not any problem with TX and RX。

when the device joined the network ，and working under PM2 mode which Poll Rate was set as 20s.

and i found that the UART Tx was not working well, when i using HalUARTWrite() to sending a array , it seems that it was interrupted

by "someone"

TX array :0xEF 01 ff ff ff ff 01 03 01 00 05

Codeing:

uint8 AttachData[12]={0xEF,0x01,0xFF,0xFF,0xFF,0xFF,0x01,0x00,0x03,0x01,0x00,0x05};

HalUARTWrite(0,AttachData, 12 );

what is matter of the UART ?

If you think it is interrupted by others, you can do HalUARTWrite in a critical section.

Hi Yikai

i remember that you had tell me the HAL part will shut down while the device going into sleep mode.

and i had disable the HAL_LED part sleep mode .(but sorry i forget where to set it)

is that same the UART will shut down while device woring under PM2 and going into sleep mode?

because i have test several times, there is noting happen in Uart TX sometimes .
and sometimes it was split by two part.

BR!

Yes, you can't do UART function under PM2. Where do you use HalUARTWrite in your application?

0 The Seven over 10 years ago in reply to YiKai Chen

Guru 11440 points

oh no!

the device was powered by battery , and it must using UART to communicate with other device.

it was like that ：

i detect a the key press signal ， and sending an array by UART0 to other devices， and then wait for UART RX data ，judging whether need to sending another array or not .

sometimes other devices was broken and do not feedback， and the local device will resent the UART data several times by a timer time out .

How could i make a critical section？

0 YiKai Chen over 10 years ago in reply to The Seven

Guru 735695 points

I have similar application and I don't think you have to use critical section for this. Do you put your HalUARTWrite in xxx_HandleKey function?

En ， the detail is like below：

if ( keys & HAL_KEY_SW_5 )//touch sensor
{

if(FS_STATE == NOC)
{
if(OpenDoor_Match == FALSE)
{
OpenDoor_Match = TRUE;

FS_PowerOn(); // remote device power on
FS_STATE = AddUser;
GetImTimes = FriGet;
osal_start_timerEx( zclDoorLock_TaskID,FS_STATECHG_EVT,WaitFSReady); // WaitFSReady ==300 ms

OP_TimeOut = FALSE; // operation time out
osal_start_timerEx( zclDoorLock_TaskID,FS_OP_TIMEOUT_EVT,ODMacthTout);// ODMacthTout ==5000ms
}
}
}

and when 300ms time out i will using HalUARTWrite （） to send the data.

I would suggest you to do the following simple test and see if UART TX can be sent correctly.

if ( keys & HAL_KEY_SW_5 )//touch sensor
{
//Only do HalUARTWrite here.
}

i have disabled all the MT task.
and the UART initial and call back function was designed by myself.

0 YiKai Chen over 10 years ago in reply to The Seven

Guru 735695 points

I always do UART init/RX callback and see no problem with this.

0 The Seven over 10 years ago in reply to YiKai Chen

Guru 11440 points

It was same ， if the device joined network，

if ( keys & HAL_KEY_SW_5 )//touch sensor
{
//Only do HalUARTWrite here.
}

this function did not working， the data will be splited by two part 。

but if devices do not joined network， it was OK。

What's your polling rate?

0 The Seven over 10 years ago in reply to YiKai Chen

Guru 11440 points

i have close the POWER_SAVING , and it was OK。

but as i said befor ， the device was powered by battery ， it should not be disable POWER_SAVING ，

Hi yikai ，

my poll rate is 2s

and when i change my code as like that

if（key press）
{
osal_pwrmgr_device( PWRMGR_ALWAYS_ON );
osal_pwrmgr_task_state( Test_TaskID, PWRMGR_HOLD );

HalUARTWrite（）
...
}

and when time out ， i adding

osal_pwrmgr_device( PWRMGR_BATTERY );
osal_pwrmgr_task_state( zclDoorLock_TaskID, PWRMGR_CONSERVE );

and then it was working nomatter it joined the network.

do you think is that OK?

BR!

0 YiKai Chen over 10 years ago in reply to The Seven

Guru 735695 points

Yes, this is OK if it solves your issue. However, it consumes more power.

0 The Seven over 10 years ago in reply to YiKai Chen

Guru 11440 points

if the device was always being POWER_SAVING， does the HalUARTWrite（）working？

you said your code was working.

does your devices working under PM2 ?

What is your POLL RATE？

did you using MT UART or private function？

0 YiKai Chen over 10 years ago in reply to The Seven

Guru 735695 points

Yes, my ZED application works with PM2 and I use my own UART init/RX callback. The polling rate is 3 or 5 seconds.

Guru 11440 points

when your device being sleep, does it could receive the UART data and send the osal msg to xxxapp.c ?

0 YiKai Chen over 10 years ago in reply to The Seven

Guru 735695 points

When device is in sleeping, it cannot receive UART data.
