According to this example, the device should be advertising RX and TX Characteristics. I also believe that when I connect to the UART app using my iphone, I should be able to transmit characters which should appear in my Realterm Serial Capture program on my PC>
I know I am running the right program. My REalterm Serial capture program is displaying the appropriate start message which I changed to "ble_app_uartStart". However, when I try to transmit a character after connecting, nothing shows up in my realterm window. Furthermore, when I connect to LightBlue app on my iphone, I do not see the Rx or TX characteristics. Instead I see the Heart Rate and Battery Service Services.
I am using Keil. I seem to be having another problem as well. In my main.c, when I try to set a breakpoint at services_init(), I am seeing a round circle with an exclamation point. However, I am able to set a breakpoint at ble_stack_init.
