iOS NRF Connect App cannot show TX and RX characteristics when connected to nrf52840-DKflashed with ble_app_uart

Hi Devzone,

I am a beginner in BLE development. I have a nrf52840-dk and want to test the ble-app-uart example in SDK-16.0.0.

I firstly use NRF connect desktop programmer to erase all. Then I open \...\nRF5_SDK_16.0.0_98a08e2\examples\ble_peripheral\ble_app_uart\pca10056\s140\arm5_no_packs with Keil uVision 5. I firstly program the softdevice flash_s140_nrf52_7.0.1_softdevice, then download the compiled UART application. Everything is straight forward. 

But when I open the NRF Connect App on my iPhone and connect to the DK, I could not find the TX and RX characteristics in the UART service. Thus I cannot communicate with the DK by writing string in the serial channel.
