I am using dragino LG308, and install the gateway bridge successfully. I change the .toml configuration file to use JSON integration and not protobuf then try to listen to the MQTT using paho python and decode using UTF-8 and basically get some gibberish:
@�GS � ��B�rI?���������� }4/5G
�@A �AQ����й�
(���������1 #@z7c���p�F"���l1o �
The encoding doesn’t seem to be any consistent encoding, and users have had similar issues:
However this was fixed by changing the configuration, but this hasnt worked for me. I have reset the gateway entirely and re-installed the bridge and tried everything and it won’t use JSON. Is there something i am missing?
When I subscribe gateway topics I saw a bad format like you faced. But when I subscribe the MQTT topic described in Application Server I can easily get device events.
