Hello,

Is someone know how to send only one data ? Because when i send common page, i receive two of them instead of one.
I didn't forget to put a 0x00 message between my two datas.
For example, when i send in a common loop : p80 (x1) and then p7 (x64)
I received : p80 p80 p7 p7 p7 => p80 x2 ??
=> p7 about x120 ??


Thanks for your help      

Hello,

Could you please clarify exactly what the problem is? Is it that you can't get your application to send only one page 80 at a time?

I'm not quire sure what you mean by 'I didn't forget to put a 0x00 message between my two datas'.

Hello,

Here is my problem : I'd send two datas (for example p80 and p7)
In a loop I'd like to send in first p80 one time and then p7 64 times
and then p80 one time and then p7 64 times ...

But i received with antwareII : p80 two times instead of one time and p7 about 120 times instead of 64 times
In spite of the fact that I sent zero pad byte (0x00) between my differents datas to be sure ANT hahave enough time to process my previous data.

Thanks for your help.      

It seems as though you are updating the transmission buffer too slow.

What do you mean by sending a 0 pad byte between your data? Try not sending a 0 pad byte, and see if that changes anything.

I've already try to don't send the 0 pad byte but the problem is still present...

How could I improve my setting to update my transmission buffer to be faster?
Here is my code :

while(1)
{
send(p80)
send(p7)
send(p7)
send(p7)
send(p7)
send(p7)
send(p7)
send(p7)
}

send( var)
{
wait RTS ready
for( i = 0 to 12)
{
send byte[ i ]
}
}

Thanks for your support.      

You should be timing your transmissions off of the EVENT_TX, not just randomly looping them.

Try updating the transmission buffer after every EVENT_TX, and see what that does for you.
