WiFi LoRa 32 (v2) LoRaWAN TxNextPacketTimer

Hi all,

For a project i am using some of the interrupt timers. Now i like to combine my project with LoRaWAN.
While reading the ESP32_lorawan.cpp file is see that a TxNextPacketTimer is connected to an interrupt timer. But it is not documented which timer is used.

My question is which of four timers is used by the LoRaWAN class?



For EPS32 LoRaWAN, the timer0 is used.
