Stephen Dickey / Mbed 2 deprecated C027_ModemTransparentSerial_revb

This example establishes a transparent link between the mbed serial port and the modem (LISA or SARA) on the C027. You can use it to use the standard u-blox tools such as m-center or any terminal program. These tools can then connect to the serial port and talk directly to the modem. Baudrate should be set to 115200 baud and is fixed. m-center can be downloaded from u-blox website following this link: http://www.u-blox.com/en/evaluation-tools-a-software/u-center/m-center.html

Dependencies:   C027-REVB mbed
