Ok, I will close the case then.

I left the problem.

Sorry for the slow response, somehow this case dropped out of my list....

Did you ever figure this out, or are you still struggling with the current consumption of the nRF24LE1 device?

Best regards

This is fixed now. Thanks a lot.

Here is my code.

#include <Nordic\reg24le1.h>
#include"hal_clk.h"

void wakeup_irq() interrupt INTERRUPT_WUOPIRQ
{
// Turn on LED
//P22 = 1;
}

void main(void)
{
		hal_clk_set_freq(HAL_CLK_125KHZ);
	// Wake up on pin P2.1 active-high
WUOPC0 = 0x02;

P0 = 0x00;
P1 = 0x00;
P2 = 0x00;
P3 = 0x00;

P0DIR = 0x02;
P1DIR = 0x00;
P2DIR = 0x00;
P3DIR = 0x00;

IEN1 = 0x08;
EA = 1;

while(1)
{
		
// Push button to go to power down mode, release button to wakeup
while(P01==1)
{

}
// Register retention mode
PWRDWN = 0x04;
// Clear power down
PWRDWN = 0x00;

}
}

In this code as long as P0.1 is tied to ground, the module is in register retention mode consuming about 0.002mA of current. Now the moment I release P0.1 pin from ground it goes into high power mode.

Now what I need is that the nrf24le1 should be in low power mode to start with and when ever there is high voltage at the P0.1 pin then it should exit power saving and resume to normal mode. I tried changing the code several ways but not able to achieve the functionality.

Sorry I am using 32 pin LE1. I will confirm this and post you the code here.

Hi Sriranjan

The issue should be fixed by now, and you should be able to open new cases.

If this is not the case please let me know 🙂

Best regards

Hi Sriranjan

Nordic support is staffed during standard office hours in Europe, not during weekends. To allow room for time zone differences we aim to provide a reply within 24 hours, not counting Saturday and Sunday.

As discussed in the other case, WUOPC0 = 0x02 corresponds to wakeup on pin on P0.1 if you use the 24-pin LE1. If the pin is high when you try to enter sleep it will wake up again immediately, which could explain why the current consumption is higher before you disable the wake up on pin functionality.

Could you double check this?

Best regards
Torbjørn

I am unable to add a new question or raise a private support ticket because there is a bug in your website and the form options wont load. Even I am unable to edit the experience the edit experience field in my profile to raise a private support ticket because the experience menu wont load. Looks like there are many bugs in the Nordic Dev zone website.
