Problem with "UART/Serial Port Emulation over BLE" Example

Hello,

I've done this steps:

  • I erased the whole chip: nRFgo Studio/ DeviceManager/nRF5x Programming/Erase all
  • I programmed the Softdevice s132_nrf52_5.0.0_softdevice.hex: nRFgo Studio/DeviceManager/nRF5x Programming/Program SoftDevice
  • nRFgo Studio closed, IAR Workbench started
  • Started Termite and selected COM-Port and 115200 Baud
  • I loaded C:\Nordic\nRF5_SDK_14.1.0\examples\ble_peripheral\ble_app_uart\ble_app_uart.eww
  • I pressed "Download and Debug" in IAR, then "GO" in Debugger
  • LED1 indicates ADVERTISING
  • Termite shows "UART Start!"

Ok, until here everything looks fine.

But then

  • I start nRF UART v2.0 on my smartphone (Android)
  • I press connect see and select "Nordic_UART"
  • my smartphone shows error message "Device doesn't support UART. Disconnected"

I also tested the wireless UART from Android nRF Toolbox, same result.

Any help is appreciated,

Mark
