'Device doesn't support uart' error on ble_app_uart_s110_pca10028

[FormerMember]

I followed the instruction here to write the program to nrf51822 and scan it with nRF UART v2.0 on Android. The nrf51822 can be connected, however, it shows 'Device doesn't support uart' when I tried to send some text. The serial port debug tool has been running on Windows and receive nothing. Then I tried nRF Master Control Panel, it can find the device but never connect successfully. Anyone meet the same problem?

Hi

If you flash the ble_app_uart example in the nRF51 SDK 8.0.1 then it will work with the nRF UART 2.0 app on Android.

I think there is a mismatch in either UUID or device name. The nRF UART app throws this error when UUID and/or device name of the ble_app_uart is different from what the nRF UART app expects. You can find the source code for the nRF UART app here. I think it was developed with Eclipse.

I would recommend to look at the ble_app_uart example and check if the UUID and the device name are the same as in your UART program.
