Xbee - API commands without response

Hey guys,

I’m facing a problem using a XBee module with a mBED LPC1768 + Application Board where the module seems to not answer API commands.

All other simple AT commands work (ATMM2, ATAP1 and ATAC), receiving “OK” from the configured UART device.

I’m using “UART_0_DEV->DLL = 156” to obtain a 9600 baudrate (the XBee default) and I managed to improve LPC1768 GPIO driver to enable RESET and STATUS pins.

Could you see something I forgot to do?

Thanks in advance.
