DA16200 Abnormal DPM and timer wake ups

HanKo 2 months ago

Hello,

my application needs periodic wake ups at the exact time. I have set up a periodic timer through the DPM manager config callback. The problem is that while there is no wi-fi connection(Abnoraml DPM) the timer stops working. There are no wake-ups by the timer anymore. Is there any solution to make it run even in the Abnormal DPM mode?

rtc_timeout (tid:5)
 [timer1_callback] Called by timer1...
!!! No selected network !!!

rtc_timeout (tid:5)
 [timer1_callback] Called by timer1...
!!! No selected network !!!
>> Abnormal DPM(1) operation after 1 second.

Wakeup source is 0x82

Hi HanKo,

Thank you for posting your question online and for your interest in our Wi-Fi products.
Yes, you can configure the DPM Manager to wake you up in abnormal sleep mode as well.
You can set the sleep time in abnormal DPM by configuring the _user_defined_wakeup_interval.
You must make sure you have defined the __USER_DPM_ABNORM_WU_INTERVAL__ macro on the config_generic_sdk.h file:

//-----------------------
// DPM Features
//-----------------------

    //
    // Enable/Disable DPM Abnormal wakeup User-timer
    //  This values are used to define DPM abnormal wakeup interval time.
    //
    //  Default values are defined in ~/library/libdpm.a
    //   : const unsigned long long dpm_monitor_retry_interval[DPM_MON_RETRY_CNT] = {
    //         ULLONG_MAX,    // Initial value : ULLONG_MAX
    //         60,            // 1st Wakeup
    //         60,            // 2nd Wakeup    : 0xdeadbeaf for no-wakeup
    //         60,            // 3rd Wakeup    : 0xdeadbeaf for no-wakeup
    //         60 * 30,       // 4th Wakeup    : 0xdeadbeaf for no-wakeup
    //         60 * 30,       // 5th Wakeup    : 0xdeadbeaf for no-wakeup
    //         60 * 30,       // 6th Wakeup    : 0xdeadbeaf for no-wakeup
    //         60 * 60,       // 7th Wakeup    : 0xdeadbeaf for no-wakeup
    //         60 * 60,       // 8th Wakeup    : 0xdeadbeaf for no-wakeup
    //         0xDEADBEAF     // 9th Wakeup    : 0xdeadbeaf for no-wakeup
    //     };
    //
    //  When enable this feature,
    //   user can set these values to any value they want
    //   in ~/apps/da16200/get_started/src/user_main/system_start.c :
    //
    //   : unsigned long long _user_defined_wakeup_interval[DPM_MON_RETRY_CNT] = {
    //         ULLONG_MAX,    // Initial value : ULLONG_MAX
    //         60,            // 1st Wakeup
    //         60,            // 2nd Wakeup    : 0xdeadbeaf for no-wakeup
    //         60,            // 3rd Wakeup    : 0xdeadbeaf for no-wakeup
    //         60 * 30,       // 4th Wakeup    : 0xdeadbeaf for no-wakeup
    //         60 * 30,       // 5th Wakeup    : 0xdeadbeaf for no-wakeup
    //         60 * 30,       // 6th Wakeup    : 0xdeadbeaf for no-wakeup
    //         60 * 60,       // 7th Wakeup    : 0xdeadbeaf for no-wakeup
    //         60 * 60,       // 8th Wakeup    : 0xdeadbeaf for no-wakeup
    //         0xDEADBEAF     // 9th Wakeup    : 0xdeadbeaf for no-wakeup
    //     };
    #define __USER_DPM_ABNORM_WU_INTERVAL__

Then you can find the appropriate function to configure this variable on the system_start.c file:

/*
 * Format of dpm abnormal wakeup interval
 *
 *  value allowed for wakeup interval
 *                 1 : mininum
 *          0x1FFFFF : maximum, 24 days
 *        0xDEADBEAF : no wakeup
 *       wrong value : < 1 or > 0x1FFFFF, set to 3600 sec (default)
 *
 *  Example:
 *     unsigned long long _user_defined_wakeup_interval[];
 *     {
 *         ULLONG_MAX,            // Initial value : ULLONG_MAX
 *         10, 10, 10, 10, 10,
 *         60,
 *         3600,
 *         3600,
 *         3600 * 24
 *     }
 */
unsigned long long _user_defined_wakeup_interval[DPM_MON_RETRY_CNT] = {
    ULLONG_MAX,            // Initial value : ULLONG_MAX
    60,                    // 1st Wakeup
    60,                    // 2nd Wakeup    : 0xdeadbeaf for no-wakeup
    60,                    // 3rd Wakeup    : 0xdeadbeaf for no-wakeup
    60 * 30,               // 4th Wakeup    : 0xdeadbeaf for no-wakeup
    60 * 30,               // 5th Wakeup    : 0xdeadbeaf for no-wakeup
    60 * 30,               // 6th Wakeup    : 0xdeadbeaf for no-wakeup
    60 * 60,               // 7th Wakeup    : 0xdeadbeaf for no-wakeup
    60 * 60,               // 8th Wakeup    : 0xdeadbeaf for no-wakeup
    0xDEADBEAF             // 9th Wakeup    : 0xdeadbeaf for no-wakeup
};

static void set_dpm_abnorm_user_wakeup_interval(void)
{
#if defined ( __USER_DPM_ABNORM_WU_INTERVAL__ )
    dpm_abnorm_user_wakeup_interval = (unsigned long long *)_user_defined_wakeup_interval;
#endif // __USER_DPM_ABNORM_WU_INTERVAL__
}

Which SDK version are you using?
