Nordic UART service

[Nour_l]

Hi , I'm intrested in using the BLE UART apllication provided by Nordic for the nRF51 422 developpement kit and I have a little question to ask and please forgive its simplicity : if jump the RX pin to the TX pin will I be receiving the msg sent by the android app provided as an RX ? Thank you in advance

Hi

The ble_app_uart example in the nRF5 SDK 11.0.0 is TX and RX both over UART hardware and over the BLE NUS (Nordic UART Service) service. This means that when you write something from UART peer device, it is fowarded to the BLE peer device. Similarly, when you transfer data from the BLE peer device, the data is forwarded to the UART peer device. So if you connect RX and TX pin together the result is that if you write data to the RX characteristic from the BLE peer device it will appear in the TX characteristic on the BLE peer device.

hi , well first thank u for having time to answer my question ... well I expected that too but i got no response from the DK ... to be more precise I tried to run the ble_app_uart example on the DK I have so i load it with IAR but it didn't work (no advertizing) so i've copied th .hex file so I got the DK connected to the android app but yet no respond in the way you explained
