LoRa 433Mhz vs RTL 433Mhz

[Alex_Poulgrain]

Hey everyone, This may be a silly question but I could not find the answer:

My understanding is that RTL433 and LoRa433 are not the same thing, both operate on 433Mhz band but different modulation. Therefore, if I flash my TTGO 433Mhz LoRa board with the TTGO RTL433Mhz OMG firmware, I will not be able to pickup other Lora devices on the 433Mhz band, correct?

Some other devices I wish to communicate with:

If this is all correct, is there an OMG firmware, like the ones for LoRa 868/915Mhz for my TTGO 433Mhz board that can convert 433 LoRa to MQTT?

The new release will enable to change the frequency with the WebUI, you will have to upload a LoRa firmware , onboard and connect to the WebUI to switch it to 433mhz.
