How to use CC2540DK-MINI with Enfora GSM2358

Is this (http://www.simplesolutions-uk.com/files/GSM2338-00_datasheet.pdf) the device that you are refering to? The device's datasheet does not have any mention of Bluetooth or Bluetooth low energy support. The keyfob and dongle in the CC2540DK-MINI can only communicate with each other, or with other Bluetooth low energy devices.

Excuse me for an incorrect question.
I know that Enfora GSM2358 does not support Bluetooth.
My question not about it.
Enfora GSM2358 has a serial port for connection to the computer.
Module CC2540 has UART and SPI for connection to external devices.
Module CC2540-Keyfob which is included into complete set SDK CC2540DK-MINI has connector for connection to programmer.
My question is: whether I can connect CC2540-Keyfob through this socket to modem's Enfora GSM2358 serial port?

 I  will be very happy to have description for interface's connector of
  CC2540-fob.  There  is not in documentation for CC2540DK.  Could you
  please to help me.

The reference design for the keyfob, including schematics, is available here: http://focus.ti.com/docs/toolsw/folders/print/cc2540keyfob-rd.html. That should give you the information you need.
