RF + LoRa + Bluetooth +

I’d like to clarify a core idea.

Reading the second sentence of the doc (“This reduces the need for multiple physical bridges”), I was under the impression that a board with the OpenMQTTGateway firmware would bridge several protocols to MQTT but that’s not the case, is it?

If you want RF and LoRa and Bluetooth and IR, you need four ESP32s, right?

But I’ve seen random mentions on GitHub of the possibility to add Bluetooth to a LoRa gateway or something like that. Is there a list of which protocols could be made to work in a single device?

For instance, I have a Heltec V2…could I add a CC1101 and have LoRa and RF one the same board?
