This is the example code under ble_peripheral/ble_uart...I hope this does both sending as well as receiving..we have not changed any code...let me know where do we need to change for seeing this..

also we want ble to be on once it is powered on..currently it is on for few seconds and ble goes off...any flag or any code where we need to enable to run ble all the time...kindly let me know.

The ble_app_uart peripheral example in the SDK acts as a "bridge" between a serial device and a wireless device, in that it receives data over serial and transports it wireless over BLE to the wireless device, and vice versa. It does not supports having two devices connected over serial without modifications. 

The example starts advertising after the initialization routine at the start of main.c. It does not turn it off.

Hi Jared,

we were able to change advertising value which is default set at 18000 to 0 ,then you will have the BLE connected as long it is on...also we were abel to get the Tx and Rx using the App...we will ping you if you further need any help from your side.

Good,

I'll close this case then, since it seems that the orginal issue has been resolved. Please create a new ticket for any future issues.
