I am having the same problem. Using a SmartRF05 EVB with the CC2540 module. I've compiled and uploaded the "CC2540EM" configuration of the HostTestRelease project. The LCD screen says "TI BLEv1.2 HostTestApp All" I have turned the RS232enable switch to enable. However, BTool is unable to get a response from the board!
I have tried 115200 and 57600 baud, but no difference.
Furthermore, I've looked through the code APP code to see if it ever calls the HAL UART functions, but it appears that it does not.
Is the CC2540EM config correct? I have also tried the CC2540EM-SBL but no love there either.
Any help is appreciated!
EDIT: a crossover RS232 cable was required. DOh it's working fine now :)
