hi,
I have an question about the zigbee module. I wouldlike to use the rx interrupt. But, when a data is recive, it does not work. If i add a "reciveChar" into my main part it work. I think it's that beacause the zigbee have an buffer.
Have you an solution to bypass the buffer ? (when a data is recive it be directly send at the pic )
I work on an ecio40 and 2 zigbee module (1 coordinator 1 end node)
Thanks

Hello,

Are you using Flow Control with the Zigbee module? If you are then you need to drive the RTS pin low to signify you are ok to receive data and this should then allow the interrupt to work.

Hi, Thanks for this answer, but I don't know what is the flow control. Can you explain me and show somes docs or datasheet ?

Hello,

Here are the Zigbee component properties. I've highlighted the Flow control option and the associated pins.
In my case the RTS pin is C0 so here is an option icon to set the pin low when we want to be able to receive data. You probably have to do this before the first and then again after receiving each byte.
Here is more info on flow control.

Hope this helps.

Well, it work ! Thanks !

Hi, I have an other question :

NodeConfigureSleep

Sets the Zigbee device sleep mode (only applicable for end node type devices) ,

Parameters
BYTE Mode 1=Hibernate, 2=Doze, 4=Cyclic Sleep, 5=Cyclic Doze UINT Timeout Time to sleep in milli seconds (ms)

Return value
This call does not return a value

I don't understand the differents type of sleep.

It's possible to wake the end device withe the "NodeWake" component ?
How it's work on the code ? It's stop ? or no ? I have an interrupt to check if the "sleep signal" is send

I hope it's clear

Nothing ? :'(
