BlueNRG-LP Virtual Timer Blocking Radio Activity

[JLee.46]

Hi,

I'm trying to setup a virtual timer, which fires every 400us, for triggering a ADC conversion.

I found that when this timer is running, even if i comment all the code inside the callback, it would block the BLE radio activity, for example advertising.

If i reduce the firing period to ~15ms, the SoC would start advertising again that i can scan it using another BlueNRG-LP.

I would like to know what is causing this blocking? Any suggestions to make my code work?

Thanks for your attention.
