I’m trying to transmit from a node made from an LPRS era-lora and and LoPy4 nano-gateway.
Same frequency, SF, preamble and so on.
The only strange parameter in LPRS module is Group ID, which seems to be something like classical SyncWord.
Nevertheless while my RF analyser see LoRa signal, the LoPy4 see no incoming frames.
PS: The LoPy4 nanogateway run perfectly with other end devices.
