Softdevice - app_timer_start() cannot start for APP_TIMER_TICKS(3600000) or more than 1023000

Hello

I am using nRF52833 based BE33 (Celium Devices) and using nRF52SDK17.0. Recently I have encountered the below issue:

err_code = app_timer_start(m_loadcell_timer_id, APP_TIMER_TICKS(1024*1000), NULL);

app_timer_start works only for  APP_TIMER_TICKS() less than 1023000 milliseconds. If I try to give 1024000 milliseconds it throws below error:

<error> app: ERROR 7 [NRF_ERROR_INVALID_PARAM] at :0
PC at: 0x00000000
<error> app: End of error report

If I want APP_TIMER_TICKS after every 3600000 milliseconds how can I do that?

Thanks in advance.

Thanks and regards,

Not possible otherwise int32_t variable will get overflowed. Instead, we can have a counter variable in the handler function, increment it to the required value.
