<![CDATA[FR8003A Unwanted Wake-up at 64 seconds]]>When I put the FR8003A in sleep mode with Bluetooth stack initialized and all wake-up mechanisms disabled, the MCU wakes up after 64 seconds. How can I prevent this unwanted wake-up? I want to wake it up only via a button and this part works properly.

I also have another issue. When I put the MCU to sleep and enable the wake-up by a push button, the wake-up occurs but the Bluetooth stack does not work! I do the wake-up mechanism just like the sample projects, What am I missing here?

I want the microcontroller (MCU) to wake up only when a specific event occurs (one that is not time-based).

All PMU domains can wake up

The issue is that the Bluetooth Stack wakes the MCU up every 64 seconds (periodically ). Why is this happening?
