enable TX notification of NUS service with bonded iOS (iPhone), iOS constantly sends TX_READY command until disconnect

We enable TX notification of NUS service with bonded iOS (iPhone), iPhone constantly sends TX_READY command until disconnect.

Can you confirm this is correct behavior.

We can ignore the constant messages in firmware, but want insure there is not something we're missing.

Hi Dave, 

Could you give more information about the TX_READY command ? On which side of the connection do you see that command ? 
Could you capture a sniffer trace of the communication ?
