BLE Link Receive Data over UART

Just got the BLE Link board up and running and am able to send data and notifications as a peripheral to a connected iphone configured as a central device using the default service/characteristics in transparent mode. Since my iphone has the ability to WRITE to the characteristic itself, how do I get the updated value over UART to my connected microcontroller? It seems there is some debug mode to deliver updates over USB to a BLUNO device, but I'm using a different microcontroller and can only receive over UART. Is there a way to poll the value of the DFB1? An AT Command for reading the characteristic would be most useful.

kulivontot 2015-06-24 00:41:28 Looks like this guy was sending a command from the BTLE central of "led_on" or "led_off" which would then be then be echoed over the UART. I'm not seeing this behavior when I write to the characteristic using LightBlue iOS app to debug. Maybe I need to write to DFB2? kulivontot
