Adafruit BLE UART problem

[Kutyus]

Hi!

I would like to communicate between rpi3 and adafruit nrf51822 ble devices, i followed this example: link text.
The RX (rpi to adafruit module) is working fine, but the TX characteristic and notification is invalid. The QLowEnergyservice::characteristics() list is contained the 6e400003-b5a3-f393-e0a9-e50e24dcca9e uuid, what could be the problem?

I use the Qt version 5.10.1, and i compiling on the rpi.

Thanks in advance: Kutyus

I tested it with Qt 5.11.0, but more deficiency detected.
The General Attribute also undetected and characteristic write is not working :(
