Lost Connection with nRF52 DK after connecting with BMD101 sensor

I am still newbie in nRF52 dk . For my project , i am trying to send data from my sensor to the mobile phone through BLE App UART. Therefore first I have flash nRf52 with the Ble App UART example. After i flash the code, i was able to communicate with via mobile phone and also pc. However after I have connect my sensor to nRF52 board, the board send  two signal to BLE App UART and after that i cannot detect my board anymore except after i have disconnect back my sensor which is connected to TX and RX. What is the problem related to this ? is it because of the buffer size ?

Below is my detail of sensor that I used and example of result shown on BLE App UART. For your information i am using nova 2i with android 7 (Nouget) 

Sensor used : BMD101

  • it just says gatt error 0x85 .. I then try to use UART example to check the whether the board are capable to read the sensor value and suddenly termite(serial monitor ) that i used suddenly not responding.. However when i try to send simple data from arduino such as the value=AAAAABBBBB with a delay every data that was send to the board by connect it to the rx of the nrf52832 board, Termite are capable to display the data continuously without any problem. After that i try to send the data without delay  from arduino, then the same problem occur. So what do you think ?
