nRF8001 stop showing up on scan after long period of time

nRF8001_BLE_UART.txt

I am using an NRF8001 with the ble_uart_project_with_dfu_template and programmed an ATMEGA328P with it. The code works great and I can scan and communicate with the ATMEGA328P via bluetooth using the Nordic Semi nRF UART v2.0 app for Android.

I leave the device on and notice that after a long period of time, hours, the unit stops showing up on the Scans and the only way to fix this is to power cycle the device. There's other code on the ATMEGA328P, reading a button, LEDs and those behavior are still working properly, it's just the bluetooth portion that seem to stop working properly.

Thank you for your time and help.

Edit 8/2 to add code attachment.

What ACI traffic do you see when this happens? What are you doing when bluetooth stops working?

I do not see any ACI traffic, the routine that is running in loop() is:

aci_loop(); and polling 2 buttons.

Can you check if you get any hits in case ACI_EVT_HW_ERROR:? That is could you create a log that shows if you receive this event? What peer device are you communicating with?
