LoPy LoRaWAN "Co-MCU"?

[Eric24]

I'm just curious, but does anyone know if the LoPy runs the LoRaWAN stack on one of the ESP32 cores, or if it treats the LoRa radio as a "modem" with its own MCU?

The LoRa chip (SX1272) is simply a transceiver, the protocol itself runs on the ESP32 core.

Currently the Pycom boards just use one ESP32 core for everything, I believe the plan is to move the network stacks to one core and leave the other free for user code.
