BLE_app_uart example with SAADC (with timer) not working

Hi all,

I am using SDK = 15, softdevice = v6, chipset:nrf52810

I have used ble_app_uart and SAADC example code for one of my application, its working fine, and next i have changed the SAADC config with timer only, by commenting PPI configaration, normally(as peripheral not with BLE) this also works fine, when i added this to ble_app_uart example then it is not working, i have followed the below link for timer ADC,

I want to develop a application based on timer ADC,Kindly check and suggest me for the same, thanks in advance.
