Syncing time for an nrf2460 tx/rx pair

[David]

The sync time for my nrf2460 seems to be about 4 seconds. Is this normal? Secondly, once the pair is synced at close distance, one or two feet, as I move away sync is lost and it again takes sometime four seconds or sometimes more to resync. Is there anyway to shorten the sync time to the range of 50 ms?

Seems to me you may have some hardware issue, because the range should be much better than one or two feet. I recommend to setup a single channel test mode and measure on the carrier, to verify the frequency accuracy and output power. Also you may want to check that the antenna is properly tuned, this is something we may help you with through MyPage account. But to answer your question, the link up time depends mainly on the configuration of number of link channels (NLCH), you may use the value 3 on both ARX and ATX for short link up time.
