@robert-hh said in Lopy4 LoRa 433mhz how to: @lennyz1988 In Raw Lora mode (LoRa.LORA), you can use region EU868 and set the frequency to 433MHz. For Lora WAN, I have adapted the repository to include region EU433. This is the link to the Pull Request: https://github.com/robert-hh/pycom-micropython-sigfox/tree/development Until that is eventually included in the standard images, you have to make you own build to include that. P.S.: You may also use that branch https://github.com/robert-hh/pycom-micropython-sigfox/commits/ctrlf-fix, which in addition includes code allowing to disable reboot on Ctrl-F Thank you for the reply. I am going to test the links you posted! :)
