Hi !

I have network(with coordinaotr, Rs nad EDs) in which EDs(are sleeping) send messages to each other.

I use acknowledge transmission (BitCloud v13).

What happens if one ED sends message to another and doesn't receive ACK? Is message dropped after a APS_NO_ACK_STATUS is received on sending ED?

Is is good to start timer and when it elapses repeat this message?

What happens when one ED sends message to another and immediately goes to sleep and receiving ED receives message and sends ACK to sending ED?
Or to make it simple : does sending ED have to wait for ACK (APS_SUCCESS_STATUS or APS_NO_ACK_STATUS) and then can go to sleep?

Thank you !

You have to always wait for APS_DataConf() before going to sleep.

OK.

When does callback functions rise?

For example, I'm writing data in flash memory and ZDO_MgmtNwkUpdateNotf() rise to interrupt my application. Can this happen?

Or ZDO_MgmtNwkUpdateNotf() will rise after I complete all jobs and BitCloud stack takes over everything?

Thanks, again !

No, callbacks can't interrupt application execution, they are called from main task scheduler.

And one more question just to be sure:

Can external interrupt(which is enabled) interrupt callback functions like ZDO_MgmtNwkUpdateNotf()?

I suppose the answer is yes.

Thanks Alexru !

Yes, hardware interrupts can interrupt any function.
