notification not receivied with timer

[mobi]

uint8_t ntime=0;
while(ntime<10)
{
	nrf_timer_delay_ms(TIMER2, (110UL));
	pin_read = nrf_gpio_pin_read(25);
	if(pin_read==0) send_debug_message("PIN=0");
	if(pin_read==1) send_debug_message("PIN=1");
	ntime++;
}

But I only receive notifications 6 times... why I miss the reset of 4 ? Connection remains connected and I can still talk to the BLE via nrf tool

BTW, send_debug_message, sends a characteristic notification to android device or nrf master control panel.

Maybe the connection interval you are using is much slower than the timer delay. Maybe some of the notifications are overlapping with each other during one connection interval, causing some notifications to be discarded.

now that is interesting point... "Maybe some of the notifications are overlapping with each other during one connection interval, causing some notifications to be discarded." any topic ? I would like to know this in detail. As I'm looking into reliable data transmissions.

I tested and now I send the message number a long as well... Now I see, index 0,1,2,3,4,5 But I don't see 7,8,9 being sent.... That is strange.

in total I receive only 9 notifications... and then I don't receive any notification even If I loop for 20 or 30 times...

I think I know the problem. I think you are sending all 10 notifications in a single connection interval. I think a single connection interval can only send 4 to 6 packets/notifications. The rest are discarded. Try using a faster connection interval, an interval time that is smaller than your timer delay.
