I'm trying to communicate between my apm2 and the mission planner, using XBee telemetry, and I always get the error "No heartbeat packets received".
When I connect the apm2 through usb the connection succeeds.
I'm using the Xbee XBP24-DM modem, and the baud rate is set on 115200.

Reflash your digimesh modules with a different firmware, I think it will be called XBP24-DP. DigiMesh is great stuff, but it will not work with the streaming telemetry, the duty cycle does not work for what you need. Fortunately, every time I have tried, the DP firmware is accepted by the DM modules.
Set your serial interface for both modules to 56k, not 115200.
Make sure both modules are set for the same network ID.
