HW PWM with BLE

I am using Da14699 development kit with sdk version 10.0.10.118

I want to use hw pwm (HW_TIMER or HW_TIMER2) with PIO1.1 or 1.6 and BLE.

The PWM freq will set 1MHz or 2MHz. (must be act when Extended sleep)

After modify PXP_Reporter Demo source code, and PWM works fine, but can't connect BLE.

Is any limitation BLE with HW PWM?

Thank you.
