My set-up contains a 1D107 HR fitness tracker (nrf51822 based) and I am flashing it using a BMP. It runs with your nRF-Arduino core. I am trying to use the BLE serial library. It works very well for some time, say 5-6 hours. After that MCU completely stops working. It doesn't connect to nRF UART app nor shows any values on the OLED screen. But when I wait until the battery in the fitness tracker is completely discharged and power the device again, it starts working. Could you please help me to troubleshoot this problem.
So far, I have tried the following.
1) I have tried to delete the Bleserial lines and see if the FITNESS tracker is working fine without BleSerial. It worked perfectly.
2) I removed all the lines corresponds to Serial Print, to see if there are any conflicts. I didn't change the behavior.
3) I removed all lines with delay, but it didn't help.

Looking forward to hearing from you.
