I have the evaluation kit EK-WT12 for Bluegiga WT12 module being controlled by a TI Launchpad. I have used the evaluation kit to communicate to a computer with SPP profile and I have sent and received data between RS232 input of the board and the PC connected via Bluetooth.
I have also used the TI Launchpad to communicate via RS232 to a computer for my desired functions. Works well. I am using a MAX232 circuit in order to convert its UART ports to RS232.
My problem is that, when I connect this microcontroller's UART ports through MAX232 circuit to the RS232 pins of EK-WT12, I see no data received in the data mode. I am not using flow control, so as told in the data sheet I grounded CTS and kept RTS floating. I connect only the GND, Rx and Tx pins to the output of MAX232.
Any ideas as to what may be causing the problem.
