Hi again!
I've tested your suggestions but still not work.
The first attempt was to "reset" the char array setting it to '\0' in the function where I get the message:
void handle_T(RF24NetworkHeader& header)
{
// The 'T' message is just a ulong, containing the time
unsigned long message;
radioMessage[0] = '\0'; ///////// <------------------------------------- HERE
network.read(header,radioMessage,sizeof(radioMessage));
printf_P(PSTR("[%lu] >> APP Received '%s' from 0%o <--------\n\r"),millis(),radioMessage,header.from_node);
// If this message is from ourselves or the base, don't bother adding it to the active nodes.
if ( header.from_node != this_node || header.from_node > 00 )
add_node(header.from_node);
}
But I still get these values:
Slave sends:
5;0;1;5100;1700;0;0;0;10;50;
Master receives:
5;0;1;5100;1700;0;0;0;0;;50;
It happens randomly. Somewhere there is a reason.
Then, I've tried a different approach. I've defined a new char array to handle incoming messages different from those I send, also, from the sketch I've added at the beginning:
char radioBuffer[40];
and then the function looks like this:
/**
* Handle a 'T' message
*
* Add the node to the list of active nodes
*/
void handle_T(RF24NetworkHeader& header)
{
// The 'T' message is just a ulong, containing the time
unsigned long message;
radioBuffer[0] = '\0';
network.read(header,radioBuffer,sizeof(radioBuffer));
printf_P(PSTR("[%lu] >> APP Received '%s' from 0%o <--------\n\r"),millis(),radioBuffer,header.from_node);
// If this message is from ourselves or the base, don't bother adding it to the active nodes.
if ( header.from_node != this_node || header.from_node > 00 )
add_node(header.from_node);
}
Well, now seems radioBuffer is always populated not more than a defined size of characters. Look here:
NODE0:
[12723631] >> APP Sending 0;0;1;4600;2100;0;0;0;10;50; to 00...
----------
12723635: APP Send ok
[12725639] >> APP Received '0;0;1;4600;2100;0;0;0;10' from 00 <--------
this on the same node.
And from other node, NODE5:
[12781575] >> APP Sending 5;0;1;5300;1700;0;0;0;0;4; to 00...
To NODE0
[12877550] >> APP Received '5;0;1;5300;1700;0;0;0;0;' from 05 <--------
This makes me crazy, what's wrong?
Please help
