Goodmorning,
i've a problem to connect my software (slave) to the hardware, it needs around 30s to find a connection,that's too much for us. 
I tried with message period at 31814 (around 1,03Hz) and 8286 (around 4Hz) but the problem persists.
The channel used is 71.
The network key is set to 0.
If connect I use the same software to connect to a ANT+ channel,  for speed and cadence, it  connects immediately.
I don't understand why the connection time is so different
 between these channels.
Can  someone help me? 
Thank you.
