Protocol stack 1.3.0 version
Where
1. Add call DHT11 acquisition events (SimpleBLEPeripheral. C of SimpleBLEPeripheral_ProcessEvent SBP_START_DEVICE_EVT events)

 if (events & amp; SBP_START_DEVICE_EVT) 
{
//Start the Device 
VOID GAPRole_StartDevice (& amp; SimpleBLEPeripheral_PeripheralCBs); 

//Start Bond Manager 
VOID GAPBondMgr_Register (& amp; SimpleBLEPeripheral_BondMgrCBs); 

//Set the timer for the first periodic event 
Osal_start_timerEx (simpleBLEPeripheral_TaskID SBP_PERIODIC_EVT, SBP_PERIODIC_EVT_PERIOD); 

//add 
//start the timer event execution cycle collection DHT11 temperature and humidity 
Osal_start_timerEx (simpleBLEPeripheral_TaskID SBP_DHT11_READ_HUMITURE_EVT, SBP_DHT11_READ_HUMITURE_EVT_PERIOD); 
//add 

Return (events ^ SBP_START_DEVICE_EVT); 
} 

2. Define DHT11 acquisition event, DHT11 a serial port to send events (SimpleBLEPeripheral. C) in the SimpleBLEPeripheral_ProcessEvent
Add

////cycle acquisition DHT11 temperature and humidity event 
If (events & amp; SBP_DHT11_READ_HUMITURE_EVT) 
{
//off always interrupt, none will be 0 data 
EA=0; 

//acquisition DHT11 temperature and humidity 
DHT11_Read_Humiture (sbDHT11_data); 

//always interrupt 
EA=1; 

//start the timer event execute serial print DHT11 temperature and humidity 
Osal_start_timerEx (simpleBLEPeripheral_TaskID SBP_DHT11_USART_EVT, SBP_DHT11_USART_EVT_PERIOD); 

//start the timer event execution cycle collection DHT11 temperature and humidity 
Osal_start_timerEx (simpleBLEPeripheral_TaskID SBP_DHT11_READ_HUMITURE_EVT, SBP_DHT11_READ_HUMITURE_EVT_PERIOD); 

Return (events ^ SBP_DHT11_READ_HUMITURE_EVT); 
} 

//serial print DHT11 temperature and humidity event 
If (events & amp; SBP_DHT11_USART_EVT) 
{
Uint8 nString [15]={0}; 

//temperature 
Sprintf (nString (char *), "DHT11 temp: % d, % d", sbDHT11_data [2], sbDHT11_data [3]). 
NPI_PrintString (nString); 
NPI_PrintString (" "); 

//humidity 
Sprintf (nString (char *), "DHT11 humi: % d, % d", sbDHT11_data [0], sbDHT11_data [1]). 
NPI_PrintString (nString); 
NPI_PrintString (" \ r \ n "); 

Return (events ^ SBP_DHT11_USART_EVT); 
} 
//add 

Results using serial debugging assistant, print data, found that the print format of a period of chaos, as shown, where is the problem? How to solve?
