uC sleeping BUT Not Waking off RDYN issue?

[Nishant Sood]

I'm right now getting uC to sleep WHEN THERE ARE NO ACI EVENTS I think I'm doing right, the uC sleeps but I'm not able to wake up despite the fact that RDYN is connceted to pin 2 and as I use ATmega328 its the lowest level hardware interrupt that should make the uC wake up but it is not happning ,I have the issue covered here >> forums.adafruit.com/viewtopic.php

I have tried both external interrupt using attachInterrupt(0, funcNAME, CHANGE); and PCintPort::attachInterrupt(2, funcNAME, CHANGE/FALLING/RISING);

IN connections the RDYN is very finely soldered to pin2 of ATmega or else the nrf8001 wouldn't work at all so its the problem somewhere in the library or my methodology/way of getting the uC to sleep!

What method are you using in the nRF8001 library , polling or interrupt ? Can you check with polling, you would want to have the RDYN line LOW as a wakeup source so the mcu will not be able to go to sleep when RDYN is low. This will be easier to verify and then we can address the interrupt.

In the hal_aci_tl.cpp file ,I encountered one ISR function named: m_rdy_line_handle() and which was handling the external interrupt on pin 3! ,I changed that interrupt addressal to pin2 but then things jammed further.

There's another bool function I encountered nameed: toggle_eimsk(true) which I think is swtiching the interrupt on pin2 :

if (m_aci_q_is_full(&aci_rx_q)) { /* Disable RDY line interrupt. Will latch any pending RDY lines, so when enabled it again this routine should be taken again */ toggle_eimsk(false); }

What you think?
