Part Number: CC2541
I have tried to perform a Simple Peripherial example with power saving but it has a big comsumption (around 6mA) I have enabled POWER_SAVING definition on preprocessor option. but it still doesn't work.
In general I what to use UART just with RX and TX wire. I have seen that this is imposible to do with POWER_SAVING but I have a personal way to make it. I have this function:
static void BlueWave_ChangeState(void)
{
bool Advertising_Enable;
uint8 new_state;
osal_stop_timerEx( timerBluetooth_TaskID, CHANGE_STATE_EVT );
GAPRole_GetParameter(GAPROLE_STATE, &new_state);
switch(new_state)
{
case GAPROLE_ADVERTISING:
{
Advertising_Enable = FALSE;
sleepModecount++;
if(sleepModecount == MAX_COUNT_ADV)
{
sleepModecount = 0;
GAPRole_SetParameter( GAPROLE_ADVERT_ENABLED, sizeof( uint8 ), &Advertising_Enable );
osal_start_timerEx( timerBluetooth_TaskID, CHANGE_STATE_EVT, WAITING_LONG_PERIOD );
halSleep(WAITING_LONG_PERIOD-1);
break;
}
else
{
GAPRole_SetParameter( GAPROLE_ADVERT_ENABLED, sizeof( uint8 ), &Advertising_Enable );
osal_start_timerEx( timerBluetooth_TaskID, CHANGE_STATE_EVT, WAITING_PERIOD );
halSleep(WAITING_PERIOD-1);
break;
}
}
break;
case GAPROLE_WAITING:
{
Advertising_Enable = TRUE;
GAPRole_SetParameter( GAPROLE_ADVERT_ENABLED, sizeof( uint8 ), &Advertising_Enable );
osal_start_timerEx( timerBluetooth_TaskID, CHANGE_STATE_EVT, ADVERTISING_PERIOD );
}
break;
}
}
How you can see. I use halSleep function. It works very well if I active the just 135 ms adv and then put the MCU in sleep mode once(MAX_COUNT_ADV) but when this is diferent it doesn't works
WAITING_LONG_PERIOD = 4000 ms
WAITING_PERIOD = 800 ms
ADVERTISING_PERIOD = 135 ms
I have though that UART could work making this: while advertising
osal_pwrmgr_device( PWRMGR_BATTERY );
then when connected
osal_pwrmgr_device( PWRMGR_ALWAYS_ON );
which is when I need UART comunicaion. but I can't perform Power Saving with empty project.
When I use my own metod the batery live go around 8 mounths but I need 1 year
Please could you help me? Im really stock on this project.
