At first, the original CC2530EM module is removed from SmartRF05EB. Then, third party CC2530 module is connected to External SoC debug of SmartRF05EB. To supply 3.3V to the external module from SmartRF05EB, R30 near the debug connector is short circuited with 0 ohm resistor. Voltage for IO pins of external module is to supply from pin 2 of debug connector. For that one, you might need to connect pin 9 back to pin 2.
To change the baud rate of UART bridge program from 9600 to 115200, smpl_nwk_config.dat or uart.c file in IAR EW is modified as shown below.
Cutecom can be launched as follow.
