Each 32 seconds and during 4 seconds, i have a blank on the communication between 2 S2B modules. An idea ? ?

I am using 2 XBEE DIGI 62B modules which are communicating, one in STA mode, the other in AP mode.
The one in STA mode send data to the one “AP mode” continuously.
The communication is working, but each 32 second (approximately) and during approximately 4 seconds, i have no communication with the controller.
Seems that the Xbee module is doing another thing and cannot send to the microController the received frame from the one in STA mode .
Have you an idea of the problem? Perhaps a parameter to be changed into the Xbee module …
