nrf52810 sleep problem

esb_ptx_V1_6_E_1_7S_PowerSupply_SleepProblem.rar

We are using powerdown() function to put the procesor in sleep mode for the said time

We are facing following difficulties

1. It does not work if we use nrf_delay_ms() function in the code

2. If we use the tmer2 interrupt to get the required dealy, and we using the variable g_u16Timer0ISRCount, it works correc but if we make this variable 0 in the code again the sleep fails
We checked if the powedown works by using a ld toggle in the ISR for a led
So please let us know the conditions in which it will work and condition in which it will not work.

The Power down , the tx_send_packet get initialzed correct as per powerdown timing. So we feel it just shuts the Rf services for given time

So its confusing how the powerdown works

Finally we want

1. to execte some of our code along with timer and other peripheral like ADC. And also propriety RF

So when we power down, the processor should go to sleep and wake up at the said time. again perform operations and go to sleep

Below is the reference code we are using and above code is the final code in which we want all the mentioned changes ..

Thank you

Please help

Hi,

The WFE( Wait For Event) instruction will suspend the processors execution until a IRQ interrupt. Which means that if you observe that the processor "wakes up" immediately then it's properly due to a Interrupt firing most probably from either the RTC or the Timer peripheral.
