I2C using processor expert

I'm trying to use I2C routines created by processor expert.  I am trying to read temperature from an I2C device and when using code similar to the examples and I see the following problem on a scope.


When I transmit the address that I need to read and the program waits for the OnTransmitData interrupt to set a flag.  The program sees the OnTransmitData interrupt flag before the Close.  The program then continues to try to receive data  and I get a "Bus not available" error.


Do I need to insert a delay?  None are shown in the sample code.


Thanks for your help.
