Guru Meditation Error in Callback

Hi!
I’m trying to get RSSI and SNR in a calback function, and recieve an error with reboot
What am I doing wrong?
I’m using LoRa.packetRssi() and LoRa.packetSnr() functions
and Wireless Stick Lite dev board

Thanx.

Update.
LoRa.packetSnr() in a callback function causes a reboot.
Case closed.
